Glass Science Glass Scrub Product Reviews

Product performed up to my expectations. I had to apply twice, and use a little more force than I expected when scrubbing but, the results were great.

It claimed to remove mineralized water spots. It does not.

Read with interest the commenta by Chuck D, John S, and Viola T. The one that was truly satisfied was the only one that used it as directed on the surface for which he product is intended! Epiphany! I agree with number three!

I tried this product and I am absolutely amazed at the results. I had some horrible water stains on my windows that had been there for at least 10 years and had never been able to clean them to my satisfaction. With this product I can actually let the sunshine in. It is wonderful and would recommend it to everyone; however,it does require elbow grease, but well worth the work.

I tried this product and found that you need to apply this with an applicator that provides a good bit of agitation. I first tried my PC with a white pad and it worked well but was not practical. Next I tried a green dish scrub pad. The rough side was a bit too harsh for the glass but worked pretty well. Lastly I used a bug and tar sponge and this worked very very well. It was gentle enough on the glass yet abrasive enough to remove the water spots (that had been on my 540 for 4 or 5 years). This product does take some elbow grease when using but works just the same.

Not too sure about this one. It claimed to remove water marks, but this is not the case. In addition, be careful when using on gloss plastic, as it crazed the black supports between my front and rear window, which created swirl marks. If you need to remove anything else besides hard water stains, it works like a champ.
