Keep your waterdrop® Signature Glasses sparkling and durable with this simple cleaning and care guide. Learn the best methods for borosilicate glass maintenance.
Quick answer
Hand-wash your waterdrop® Signature Glasses with mild soap and warm water, then dry immediately with a soft cloth to keep them clear and streak-free.
Why borosilicate glass needs gentle care
Your Signature Glasses are made from borosilicate glass, which is more heat-resistant and durable than standard glass but still requires careful handling. Avoid sudden temperature changes—don't pour boiling water into a cold glass or place a hot glass on a cold surface—to prevent thermal shock.
Borosilicate glass is non-porous and won't absorb flavors or odors, making it ideal for your microdrink. However, it can show water spots and fingerprints more easily than textured materials.
Common stains and how to handle them
Over time, you may notice cloudiness or mineral deposits from hard water. This is normal and not a defect. A quick soak in a 50/50 white vinegar and water solution for 15 minutes will dissolve the minerals. Rinse thoroughly and dry with a lint-free cloth.
For stubborn tea or coffee stains, make a paste of baking soda and water, gently rub it on the stain with a soft sponge, then rinse. Avoid abrasive scrubbers that can scratch the glass.
Diagnosis: Is your glass cloudy, spotted, or scratched?
- Symptom: Cloudy film or white spots: Likely cause: Hard water mineral deposits. Corrective action: Soak in a 50/50 white vinegar and warm water solution for 15 minutes, then wash with mild soap and dry with a soft cloth. If cloudiness remains after two soaks, the glass may have etching from abrasive cleaners—this is permanent but purely cosmetic.
- Symptom: Streaks or water spots after drying: Likely cause: Air-drying or using a rough towel. Corrective action: Hand-dry immediately with a lint-free microfiber cloth to prevent mineral spots from forming. Switch to filtered water for rinsing to reduce mineral content if spotting persists.
- Symptom: Scratches or dull appearance: Likely cause: Using abrasive sponges, steel wool, or washing with metal utensils. Corrective action: Switch to a soft sponge or silicone brush. Do not use abrasive cleaners. Once scratched, borosilicate glass cannot be polished. Replace the glass if scratches become deep or if the glass feels rough to the touch.
