Nano-Tech Repellent Wash - Multi-Surface Glass Cleaner Spray for Granite, Wood, Stainless Steel & Kitchen Appliances - Cleaning Supplies - Made in USA 1 Gallon

We renovated out bathrooms last year putting in glass shower doors in both bathrooms. We've been using this product ever since as it was recommended by the shower door company. Our glass has stayed crystal clear.

This is perfect for so many things. Glass cleaner, quartz polishing, and it does many other jobs. I spray my porcelain sink and it keeps the salt from the soft water sticking to it. Water beads up. Our shower installer used it on our shower. It wipes down so easily. The secret is you must use microfiber cloths, with NO fabric softener on them. Also, go lightly on the spray for mirrors and glass because it will look streaky if you use too much. You need to buff it out with a clean microfiber cloth. I used it on my dishwasher, fridge too. It really is amazing!

Incredible Streakfree Cleaning Power for EVERYTHING

Water stains are a constant headache in my water district, and I’ve tried just about everything. It takes a lot of elbow grease for the toughest buildup, but once you make headway on the older stains, it will keep them from returning. It’s an absolute MUST for maintaining new glass and keeping it from clouding !!

It works well on our glass shower.

It cleans windows, mirrors & other surfaces with no streaks and keeps them from fogging. A Godsend here in Florida.

This keeps our shower doors sparkling even with hard water

I've been using this for about two years and my glass is perfectly clean. I apply it once a week. I don't think it cleans though. If you keep treating, the glass stays perfect, but if the glass is already spotted then I don't think this is where you start.
