Frequently Asked Questions
Are these Frost Buddy models vacuum insulated?
No. These models use double-walled stainless steel insulation rather than a true vacuum. That makes them lighter and more affordable, but vacuum flasks typically hold heat or cold longer.
Can I use these as travel mugs for hot coffee?
You can convert them for hot drinks with the optional leak-proof lid sold separately; expect shorter hot retention (manufacturer notes about 4–6 hours with lid) compared with vacuum travel mugs.
How do I clean the inside and avoid rust or coating wear?
Rinse and hand-dry after use; stainless interiors clean easily. Avoid abrasive scrubbers on painted or matte finishes to reduce wear. For long life, let them dry fully between uses and avoid leaving salty or acidic liquids inside for extended periods.
