FREQUENTLY ASKED QUESTIONS

We offer a one-year warranty from the date of purchase. It does not cover regular wear and tear, such as dents, scratches or chipped paint from the bottle being dropped, damaged, run through the dishwasher, etc, but it does cover manufacturing defects, such as leaking caps & bottles that no longer insulate. Please fill out our replacement form, include as many details as possible and attach photos of your manufactured defected product from all angles. (Please note if your bottle qualifies for a replacement the replacement will be the same size and color unless the size and color are no longer available. Unfortunately, if you have a bottle with a custom logo, we are not able to screen print or laser engrave the artwork on your replacement bottle.)

We do replace manufactured defective caps free of charge. Please contact our customer service team using our replacement form. Include as many details as possible and attach photos of your manufactured defected product from all angles.

Most of our caps are available for purchase on our LIDS & ACCESSORIES page.

Nope! The rattle means that a small metal disk that is used during the vacuum-insulation process has become dislodged. This will not affect the insulation of your bottle but if you can't live with the noise, please fill out our contact form or call us at 1-800-849-5185 and we will send you a replacement bottle.

No. Our bottles are made from food-grade stainless steel which does not leach so our bottles do not require a lining.

Aluminum can leach into water and therefore aluminum water bottles require a plastic or epoxy lining. Our bottles are made from food-grade stainless steel which does not leach so our bottles do not require a lining.

We do not recommend washing your stainless steel water bottle in the dishwasher. Doing so will not damage your bottle or your dishwasher but may cause wear or discoloration of the paint on our colored bottles. Instead, hand wash your bottle with a non-abrasive dish soap. For a more thorough cleaning, add 1 teaspoon white vinegar OR baking soda to the bottle, fill 3/4 of the way with warm water, close and gently shake. Rinse thoroughly and let your bottle air dry with the cap off.

Yes, your double-wall stainless steel bottle is safe for both hot and cold liquids and will keep your drink at the desired temperature for hours. CAUTION: the lip of the bottle is not insulated and may become hot. Use caution when drinking from any FIFTY/FIFTY® bottle containing a hot liquid.

We do not recommend using straws with hot liquids. The heat can warp the straw, potentially causing spills or burns. For your safety, please enjoy hot beverages directly from the bottle or cup.

Yes, you can put carbonated beverages in your double-wall stainless steel bottles. CAUTION: avoid agitating carbonated beverages as there may be a build-up of pressure which could cause your bottle to leak or the liquid to splash out unexpected when you open your bottle.

Yes, you can put alcohol or acidic liquids in your double-wall stainless steel bottles. Our bottles are made of food-grade stainless steel which does not leach and will not be damaged by alcohol or acidic liquids. Be sure to thoroughly clean you bottle and cap after filling it with anything other than water to remove residue which may spoil.

Do not put your double-wall stainless steel bottle in the freezer. Liquids expand during the freezing process and will damage your bottle even if you only fill it halfway or leave the cap off. Instead, try filling the bottle with ice cubes the day you need it, which will very slowly melt, providing ice cold water.

Some of our bottles can become magnetic while others do not. It can happen during the cold forming step of the manufacturing process. Cold forming is the process that bends the stainless steel to form the bottom and neck. After the stress and extreme pressure of cold working, the stainless steel may exhibit a strong response to a magnet even though the elemental make-up of the steel has not changed.

Our lids are manufactured out of Polypropylene (PP#5), a BPA-Free and non-leaching plastic.

Our FIFTY/FIFTY® stainless steel bottles are manufactured in China.

No. Hot or warm liquids may build up pressure within the bottle and cause the flip cap to open unexpectedly and spray contents.

Some ingredients such as pancake batter may also build up pressure within the bottle. When mixing these types of ingredients, users should hold a finger over the flip cap while shaking and use caution when opening the flip cap. Always point the spout away from the face when opening the flip cap.

FIFTY/FIFTY® is committed to the highest standards of product safety and quality. While our current stainless steel, double-wall, vacuum-insulated bottles use lead-containing plugs that meet all safety standards, we're moving forward. Our goal is to transition to completely lead-free vacuum-insulated bottles by Summer 2025. This change underscores our dedication to safety, quality, and environmental stewardship.
