HOW CAN I CLEAN VERY TOUGH BURNED ON MARKS FROM VISION GLASS COOKWARE?
Soak the cookware in dish soap and water overnight. Any dish soap works. Most people recommend Dawn, but I’ve found that Dawn is a little too gentle. It works, but it takes more soap if you use Dawn. After soaking, empty the pot (do not rinse) and scrub with a Brillo pad. Yes, I’m serious. The Brillo will NOT scratch the glass as long as there is a slight soap residue in the pot. I own Visions and have clean it this way for 20 years…not ONE scratch. After scrubbing, rinse well. If any burned on food remains, add just a drop of dish soap and repeat the scrubbing with the Brillo pad. If you’re nervous about using Brillo on glass, try an experiment. Take a piece of glass you are throwing away or recycling…an empty jar works. Squirt just a little dish soap on it. Then scrub the glass with Brillo. Rinse well. Any scratches? Nope. 🙂 Good luck.
