ProClean Hard Water Spot Remover - For Glass, Metal & More - Includes Applicator Pad - Water Stain Remover Kit - Use on Car Window or Shower Door

I have two showers in my house with partial glass surrounds, and while on one we always squeegee after showering, the other not so much and had developed heavy crusting and fogging to the point where it looked like frosted glass. I had tried several methods but nothing was getting rid of enough of the buildup to salvage the glass, and as a last-gasp effort saw this on Amazon and tried it. It did take some good elbow grease to work on each section (did about one foot-square area at a time), but I was FLOORED at the result of clean and clear glass once again! I had all but given up, yet this brought the shower glass back to near-original condition. It's always good to find 'that' product that you know will just work!

I have a 2015 truck that is always parked outside. I take care of my car but the windows were still getting spotted and ugly. I used this to clean the windows and was very very very happy with the results.

This is the only product I have ever tried that removed etching. It makes even the oldest, most stained and streaked glass crystal clear. It didn't take a lot of effort either.

Expensive but work

I highly recommend if you have water irrigation like rust type on glass, I couldn't get rid of my back window stain n try several methods n I even was about to spend over 500$ to get the glass replaced until I ran into this n man Iam so glad it got rid of the stain n now like new new like it was never there I extremely recommend it for glass...

Why did you pick this product vs others?:I chose this product due to YouTube influencer Fix This House did a demonstration of product.,however , I found the product ineffective. The influencer showed hard water minerals residue being removed on included scrub pad. I see now, after using , the residue is the dried product collecting on the scrub pad. Completely ineffective. I’m 2 days past return date , sadly, I’m out $30. Save your money , this doesn’t work on my shower doors.

There was a lot of scrubbing and wiping and more scrubbing 4 and 5 times on repeat and I finally managed to get a small section (3 inches by 20 inches) of my window almost cleaned from the hard water deposits. I would say this product works if you only need a small area cleaned up and if you have a lot of patience to repeat the steps many times. Definitely not a miracle cleaning product. Definitely need more than the one small sponge they send.

Outstanding product, made quick work of water spots on my motorhome windows. My windows have the light bronze glaze on them and I was worried about scratching that, came out perfect and polished.
