Care Guide

Simple care, lasting quality

Practical guidance to help preserve the finish, performance and longevity of your GERM drinkware.

Everyday Care

To maintain the appearance and performance of your product, we recommend washing with warm water and mild detergent after use.

Most GERM products should be hand washed to preserve finishes, seals, and exterior coatings.

After cleaning, allow all components to dry fully before reassembly.

Lid and Seal Maintenance

For optimal performance, seals and lid components should be cleaned regularly to remove residue that may affect sealing.

Ensuring all parts are correctly assembled will help maintain leak resistance during everyday use.

Temperature Performance

Many GERM bottles and tumblers use double-wall vacuum insulation technology designed to maintain beverage temperature for extended periods.

Preheating with warm water or pre-cooling with cold water can further enhance temperature retention.
