GlasWeld ProClean Hard Water Stain Remover for Glass & Metal – Non-Acid Mineral Deposit & Water Spot Remover for Cars & Shower Glass Cleaner - Removes Hard Spots from Windows – with Applicator Pad

Bought a truck that has a weird film on all the windows. We tried everything, even pumice stone. This stuff really works. You have to follow the directions. I also used an electric buffer pad to do the muscle work. No smell. Easy to use. No scratches and now you can see clearly through the windows. Good price for the product

This product works great to remove hard water stains and soap residue. With a little “elbow grease”, all of the stains were removed revealing cleaned, streak free windows.

Previously waterspot-etched and Florida-sun-soap-scum encrusted car windows are now absolutely new-showroom quality. I am amazed. This product works where others have failed, including an auto detailing shop’s attempt. I used the 0000 steel wool method. I parked the car in the shade and ensured the glass was cool to the touch. To start the job, I thoroughly cleaned each panel with Windex and paper towels. Then I started the application process as follows. After lightly dampening the glass with water, I applied a healthy quarter-sized dollop of the product to the steel wool pad. I used petting-the-dog’s-head scrubbing strength in a circular motion. I continued adding additional product to the steel wool as needed to ensure there was enough product applied initially throughout the section I was working. I worked in sections; for example, I did the rear window of my minivan as 3 separate sections. Over a few minutes’ time, the row-by-row, methodical circular scrubbing turned the liquid into a dried paste. Once dried, I then buffed off the paste with a paper towel, and checked the result. The first round removed nearly all of the debris. I decided to do two rounds per section as it was, truly, 100% successful after two rounds. So, this not a blink-of-an-eye correction, but in my experience this wasn’t difficult.. Some reviewers have mentioned scratched glass after using this 0000 steel wool method. I wondered about that. I did not have that outcome here, happy to say. I have read that the hardness of the glass is superior to the hardness of 0000 steel wool. Perhaps the scratching other reviewers encountered was a result of the debris already on the glass, once set free by the steel wool, actually led to the scratching. I’d suggest you wash your glass thoroughly before starting the process, to minimize the risk of any debris causing damage.

I didn't think to take the after photo soon enough to get it in the same spot -- but I think you can still see a big difference! this product definitely made it easier to scratch off the baked on water spots in our aquarium. I still needed a lot of elbow grease and a straight razor, but I got more of the build up off than I have been able to with other solutions. Although I used the product outside, I didn't think the smell was overwhelming at all like some cleaners.

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!

SUPER SUPER SUPER Product. I’ve been trying to remove water streaks & spots from my glass shower stalls to no avail. I typically dry the glass walls after each use but I had foot surgery. It was hard enough showering on one foot for a whole month let alone drying the glass walls & so I figured it could wait. Well needless to say, after a month the water streaks & spots could not be removed. I’ve spent a considerable amount of money & time on different products on the market through google search & desperate enough to ask for advise on the community facebook page. Lots of advice & tips & nothing would remove them. I even consulted the glass manufacturer where we purchased the shower stall from 6 years ago. they basically said that the glass likely etched due to well hard water & not sure any product could remove the etching. I refused to give up & continued to look for other products. I came across this while looking on amazon for a totally unrelated item. I hesitated for a month before ordering. It was a bit pricey for an 8oz bottle & didn’t really have any faith it would work. I received it today & within minutes I tested a small area as recommended. Took seconds for a square foot area & not much pressure. When the solution faded, i wiped with a damp microfiber cloth & then wiped dry with a dry cloth. I could not believe my eyes. I tried wetting & drying again & again the glass was back to it’s original clarity. I asked my daughter to come by just to make sure it wasn’t just me not seeing the streaks & she assured me that in fact that the square foot area was streak free. I’m SUPER SUPER SUPER happy with this product & wholeheartedly recommend to anyone who has same need. I don’t know what kind of magical wizardry is in this product but you have one happy lady here. THANK YOU GlasWeld. I would give 10 stars if possible.

Love this product.Really easy to apply with a damp sponge to any glass.Let it dry and then buff it off with a microfiber towel.Everything comes out so shiny and clear

Had badly etched shower doors. After a couple of hours of polishing and scrubbing, doors are 95% back as new. Big scrub pad included works great and is tough as nails. Had to use 3/4 of the bottle for one shower, bit this was for 7 years of build up on well water. And the pad shows little signs of wear. Highly recommend, but lots of elbow grease needed.

Was disappointed as this product does not work on my shower screen soap scum even scrapping with Bosch Cordless Universal Brush

I don't know what I would have done without this product, it is a pity it comes all the way from the USA to the UK. I would highly recommend this product, it works.

Easy to use and only product thus far of many we purchased that removed soap scum off shower door. Need to do at least 2-3 times but not hard to do just time. Highly recommend to use to take the soap scum off shower doors and glass. Thank you

I have tried to polish glass and it would not get rid of the water marks. It took a bit of an effort doing it by hand but it removed all my water marks from all the windows. I was did 2 passes on the glass and it looks great even water beads off the glass now. Pictures dont do it justice.
