Invisible Shield Water Spot & Stain Remover Scrub 8 fl. oz. Removes Hard Water Spots and Soap Scum from Glass and Multi Surface by UNELKO- Clean-X Invisible Shield 2 Pack

This really works. It doesn't do much for etched in water spots (nothing does), but it's great at removing newer ones, along with other buildup. HOWEVER, I'm way more impressed with it's other capabilities, such as oven cleaning. I'm a self employed house cleaner and I've tried many products. I'm always looking for cleaners that do double duty, as to lighten my caddy and because it's more cost effective. This product is definitely on my 'musts' list. I cleaned this oven with Invisible Shield, a scrub daddy, dish soap/water, and a scraper. Took me less than half hour, including the grates. Works well on gas ranges and glass stovetops, too. Seriously incredible.

I own a commerical/residential cleaning business and a seperage window cleaning business. I use this product at both. Effortless!!! Wipe it on, let it sit, do it's work and wash it off. Hard water spots gone, just fresh clean glass.

I have been using this for years and have not found ANYTHING that works as well on glass shower doors/walls. I keep this on hand and live it

Followed the instruction perfectly, 3 Applications and a couple hours later there was not enough bang for you buck. If you live in an area with hard water this is not the product for you. Our water in the house goes through a softener and this product did remove some of the minor water spots but i expected better results after 3 applications.

This cleaner really works like it says it will! I had some hard water spots (we're on a well) on our glass shower door. I had tried regular glass cleaners and straight ammonia and the spots persisted. This cleaner when combined with a little light scrubbing took the water spots right off. I'm a believer!
