6-1. What materials are used for Hydro Flask?

We still use a Question-and-Answer format to answer these questions.

Q: Is Hydro Flask stainless steel?

A: Yes its material is High-quality Food grade stainless steel.

There are over 150 grades of stainless steel, and there are around 15 grades that are commonly used that are suitable for an outdoor or kitchen environment.

It does not easily corrode or rust except in low-oxygen, high-salinity environments.

Q: What type of Stainless Steel Hydro Flask uses?

A: Normal Raw material is Cold rolled Steel coil. Before 2000, lots of raw materials are imported Stainless Steel from South Korea.

With the Technology and Strength development of the China Iron Industry, the China domestic Stainless Steel replaced most of the imported stainless steel raw material.

Some brands raw steel are more suitable for drinkware manufacturing and more reliable, like ZPSS, SKS, Hydro Flask uses ZPSS till now.

A quality Inspection report is a must to ensure the stainless steel is of correct element ratio and suitable for producing stainless steel water bottles.

Q: Can a Hydro Flask rust?

A: No, it does not easily corrode or rust in Conventional use except being continuously used in low-oxygen, high-salinity environments.

Q: Is there any lead in steel?

A: No, it is lead-free in such 18/8 stainless steel.

Q: 304 Stainless Steel Vs 201 Stainless Steel

A: Yes there is Steel 304 behaves much better than Steel 201, in both Processing and Surface Finishing. Hydro Flask uses Steel 304 instead of Steel 201.

304 stainless steel is one of the most desired and widely used grades of stainless for the tableware area. Durability and beauty have made this 304 the hottest grade on the market.

Type 304 stainless steel is a T 300 Series Austenitic Stainless Steel. It has a minimum of 18% chromium and 8% nickel, combined with a maximum of 0.08% carbon.

This alloy is extremely durable, as well as favorable for creating a beautiful finish.  The welding is excellent without affecting the appearance or corrosion resistance in the joints. Under regular environmental conditions, the 304 has lifetime durability

201 stainless steel is not very corrosion-resistant, but the low cost has made it more and more commonly used. Austenitic alloys, like 304, these alloys are not comparable to 304 in terms of durability and resistance to corrosion.

They were created to cut the cost of Austenitic alloys by replacing most of the Nickel with Manganese or Nitrogen.

The problem with this is that neither Manganese nor Nitrogen is nearly as resistant to corrosion as Nickel. These alloys do not stand up to the elements nearly as well as 304.

Q: Are Hydro flask bottles BPA-free?

A: Hydro Flask bottle body is in the material of Aviation Grade Stainless Steel, Matched with Virgin Raw material plastic lid and medical grade Silicone seals, these Hydro Flask bottles are BPA free, Lead-Free and Phthalate Free, safe to load water and beverage for drinking.

6-4. What’s the common way to brand Hydro Flask Stainless Steel Water Bottle?

Technology develops so quickly that so many Surface furnishing options and LOGO WAYs are there for choice.

The most economic surface finish is Brushed Stainless Steel Native Silver. The logo could be realized by Silkscreen printing, Laser engraving /Eroding, Debossing or Embossing, Water Transfer Printing, adding directly onto this finish.

Colorful Spray painting is also popular to use.

It could be transparent painting, semi-matt painting, or matt paint. For this finish, the logo could be added by Heat transfer printing, Air Gas printing, Laser Engraving, UV printing.

Gradient painting is available.

Lead-Free Powder coating is the latest finishing way.

Compared with Spray painting, Powder coating has the advantages of being much durable and stable of the coating layer.

The logo could be made by One-color Silkscreen printing, UV printing (multi colors logo is available). Gradient coating is a hot seller since 2018.

Glowing bottles/flasks/mugs could be completed perfectly by powder coating.

Electroplating: most deluxe and amazing surface finish way.

It is so shiny, the bottle/flask/mug surface looks like a real mirror, lots of colors could be realized there.

Single color or mixed color could both be produced. Electroplating is really magic and amazing. For multi-color electroplating, each product is of unique design, no exact same color display could be found in mass printing. The surface could be semi-matt, shiny, crack.

Different logo ways have their own advantages and disadvantages.

Silk printing: most reliable printing way in durable, but limited by logo color quantity, the flatness of the printing area.

Heat transfer: could print multi-color logo in one time, but limit by bottle shape, cannot fully cover the outer surface.

Water transfer printing: could print different colors at one time. Disadvantages: The logo will be some shape changed, unavoidable pollution.

Air Gas printing: could print different colors all together, could fully cover even the round bottle surface. The only disadvantage is there is slight fading for patterns with special dark colors and ship in the hot season.

UV printing: Have 3 dimensions logo, attractive hand feeling, could add a different color logo onto Powder coating surface.

Disadvantage: The cost is expensive, the logo could be scratched by nails intentionally on the dark powder coating surface, special painting needs to be added to ensure durability.

Chapter 7: How to maintain a Hydro Flask?

Complete care instructions / Maintaining of Hydro Flask

The Hydro Flask is made from durable, 18/8 (#304) stainless steel,

And well designed to be lightweight yet extremely strong and break-proof.

If this flask is well taken care of, it may very well last your lifetime, and keep your Hydro Flask Stainless Steel water bottles Fresh.

Here are a few tips to enhance the enjoyment of your using your favorite drinkware.

For safety and hygiene, wash your BOTTLES, CUPS, and CAPS prior to initial use.

Hand washes only. We recommend handwashing Powder coated and all vacuum insulated Hydro Flasks stainless steel water bottles.

Clean Hydro Flask using warm water and detergent after use. Rinse thoroughly with hot water. Do not immerse in water. Dry thoroughly after leaving it to drain.

If your bottle or cap seems to be retaining flavors or smells, use diluted vinegar and soak them in it overnight.

To achieve the best result from your Hydro Flask (or Coffee travel mug), pre-fill before use with hot water for hot drinks and ice water for chilled drinks for several minutes.

Do not overfill, hot liquids can burn users.

After filling, ensure the lid is tightly closed. Do not over-tighter the lid.

Do not put your Hydro Flask (or Coffee travel mug) in a dishwasher.

If your Hydro Flask (or Coffee travel mug) has not been used for some time, rinse with warm water to remove any residual odors.

Store with the lid off.

Keep away from children when filled with hot liquids.

Do not microwave or use a conventional oven.

Don’t heat or freeze Hydro Flask or Double wall stainless steel bottle. Doing so could damage it.

Do not store any carbonated drinks as they may cause the lid to eject forcefully.

Avoid abrasives, solvent and bleach products.

After closing, please pour out the residue fluid inside the lid.

O-rings, gaskets extend the life of your bottle so it’s running as long as you are. Leakage may be found after frequently using your Hydro Flask, it is normal, what you need to do is to replace the watertight O-rings or silicone gaskets which are Available upon request.

For hygiene, before filling your Hydro Flask or using it to drink, wash your hands after using the washroom, change diapers, blow your nose, coughing or sneeze, and after touching pets.

Protecting UV/3D Printing on Powder Coating Flask/Bottles

When we debuted our UV/3D Printed bottles, the most important thing to us was to find a safe and durable Painting that also looked attractive.

We reviewed and tested dozens of different paints and selected domestic solid ink and imported ink for UV printing, both contain no toxins or lead.

Kindly NOTE that the edge of the powder-coated Flask/Bottle will leave the color line when being scratched onto white paper, acting like a Painting Brush. This is the character of Powder coating, it does not matter with Issue in Coating Quality!

Just like anything that’s painted, it is possible to chip or scratch the small bit of paint on your Hydro Flask stainless steel bottle.

To prolong the life of your paint, hand wash your Hydro Flask stainless steel water bottle and don’t use abrasive agents to clean it.

DENTS and SCRATCHES will accompany you throughout your travel

Under normal use, your bottle should last forever. The colored Hydro Flask stainless steel water bottles are powder coated so they’re pretty resistant to scratches but still scuffles with rocks or metal are likely going to scratch it.

You might pick up some scratches and small dings along the way, but I think these battle scratches are cool, they are a memorable history of your travel journey.

Fortunately, the latest designed Silicone Sleeve helps so much in protecting the bottom of Hydro Flask from dents and scratches in dropping to the ground.

DO NOT DO these with Hydro Flasks stainless steel water bottles:

Put in the Fridge (put in Freezer to Freeze a Steel bottle), because Liquid expands when frozen, the bottle will get deformed and will lose insulation properties, affecting normal use. Thus it is prohibited to put it in the fridge except for a short period pre-chill.

Put in microwave

The steel will block the drink from heating up and metal can catch fire., thus Do not Put in the microwave.

Cooking or heating up in the fire

For Hydro Flask and other double-wall insulated bottles, this is prohibited.

Don’t put an insulated or double-wall bottle in the fire. The heat won’t pass through properly, and the bottle will likely explode.

Stainless steel is pretty tough, but if you leave your Flask / Bottle in high heat (in a hot vehicle, for instance) for too long, the shape could warp and distort. Thus Keep your Flask / Bottle out of the heat.

More detailed answers and reasons are listed below.

More FAQ:

Q: Can you put ice in a Hydro Flask?

Q: Can Hydro flasks hold hot water?

Q: Is a stainless steel water bottle used for hot and cold water?

Q: How long does a Hydro Flask keep your drink cold?

A: For all the above 4 questions, Hydro Flask and Stainless Steel Water Bottle are environment friendly, as it is made from natural elements, they can be recycled easily.

Stainless steel is the healthiest for holding hot water as well as cold beverages too, Same as other Stainless Steel double wall insulated vacuum water bottles, Hydro Flask is a perfect container for both hot water and iced cold beverages.

It keeps hot drink hot for up to 12 hours and cold drink cold for up to 20 hours.

Q: Is it safe to put lemon water in stainless steel water bottles?

A: Safe is not a stagnant condition: lemon juice is highly corrosive and extensive contact w/metal—even stainless steel quality—containers –same to Hydro Flask, could cause micro-particle metal leaching which could result in a consumer also inadvertently ingesting micro-metal particle corrosion.

If lemon water is only temporarily stored in a stainless steel container—such as poured into an iced stainless steel cup for immediate consumption—it’s most likely safe for drinking right then

It is not recommended to put carbonated beverages in the Hydro Flask since the pressure can cause the liquid to spurt out of the lid.

Alcohol, some juices, and dairy-based beverages can spoil and may cause excessive pressure buildup in your beverage container, which can lead to lid failure or injury.

Remember if you are using your Hydro Flask to enjoy a fizzy soda, some bubbly, or other carbonated beverages, please use special caution when opening.

Q: What Else can we use Hydro Flask to drink?

A: Any drinkable liquids with lists:



Workout drank (amino, energy, etc.)




Iced coffee

Beer should be fine, just be very careful when opening the lid!


Q: Is Hydro Flask machine washable? / Is it dishwasher safe?

A: There are no known safety issues; stainless steel is non-reactive so the Flasks do not leach and do not have to be lined.

Stainless steel generally is less dishwasher safe and probably not a good bet in hot climates since the metal will heat up more quickly than its plastic counterpart.

Hand wash is requested to maintain the normal vacuum thermos function thanks to the double-walled insulation structure.

Q: How to clean a hydro flask water bottle

Q1: How do you get rid of a Hydro Flask smell?

Q2: How to Deep Clean a Hydro Flask

A: All the above 3 questions are on Hydro Flask Clearance.

Hydro Flask Stainless steel water bottles are becoming more and more popular. These bottles are break-proof, durable, and easy to keep clean.

Hydro Flask’s Durable 18/8 pro-grade stainless steel construction won’t retain or transfer any flavor.

While some flavor and scent can randomly occur in improperly cleaned Hydro Flask stainless steel bottles, it is easy to remove.

You can keep your Hydro Flask stainless steel water bottle clean, fresh, and odor-free by using the following methods.

Method 1: Bleach and Water

  1. Fill the flask to almost the top with hot water
  2. Add a teaspoon of bleach
  3. Fasten on the lid and leave the mixture to stand for 5-10 minutes
  4. Rinse the vacuum flask out with hot water and leave upside down on a dish drainer to drain completely.

Method 2: Baking Soda

This method will take a little longer but should still deliver good results.

  1. Fill the flask with hot water.
  2. Add 2 teaspoons of baking soda.
  3. Leave to stand overnight
  4. Rinse out thoroughly the next morning and dry as above

Method 3: Lemon Juice

This method gets rid of a smelly odor in the thermos flask and cleans

  1. Squeeze the juice out of a lemon
  2. Fill the thermos flask with boiling water, Pour the lemon juice in with it
  3. Let Flask stand for half an hour.
  4. Tip the water out. Allow to air dry with the lid off.

Q: How often should you wash your bottle?

A: Clean your water bottle at the end of each day. If you’ve used your bottle at all during the day, clean it.

The experts suggest reusable water bottles –including Hydro Flask- should be washed each time after use. You can rinse your bottle with hot water over 71 degrees Celsius.

With temperatures of about 55 degrees Celsius, use soap with some kind of cloth or sponge and make sure you’re giving your bottle a thorough rinse. Dry your water bottle after that.

If you’re just drinking water out of your bottle, you barely even have to clean it. You could Regularly go weeks without cleaning the bottle, other than a quick wash of the mouth part every week or so.

The only time to use a soap and water rinse is if you have some veggie juice or tea/coffee in the bottle.

The Hydro Flasks are easy to clean, usually, a water rinse will do it, but if you leave smoothie/juice in it you’re probably going to have to use a brush to clean it perfectly;

Another easy way is to have it soak with soap and water overnight. In the morning pour the contents out, Rinse the inside of the bottle and Air Dry.

Enjoy your adventure!
