Frequently Asked Questions
Can I put smoothies with chunks or seeds into these wide-mouth bottles?
Yes — wide-mouth bottles listed here accept standard ice cubes and thicker textures. For best results, use a wide-mouth screw lid or remove the lid entirely to fill and clean. Straw lids work for thinner shakes but can clog with chunks.
Are any of these bottles dishwasher safe?
The Hydro Flask 64 oz wide mouth is advertised as dishwasher-safe (lid disassembly recommended). Many Coolflask gallon models advise hand washing to protect the finish and accessories. Check the product care notes for each bottle.
Which material is best for preventing rust and flavor transfer?
18/8 (304) stainless steel is the most common choice and resists rust and flavor retention when cared for properly. Avoid leaving acidic drinks in bottles long-term and make sure seals and lids are dried between uses to prevent corrosion in crevices.
