GlasWeld ProClean Hard Water Stain Remover for Glass & Metal – Non-Acid Water Spot Remover with Applicator Pad for Glass, Car Windshield, Shower, Mirror & Boat Windows - Bathroom Cleaning Supplies

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.

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

After living for a year with glass that had 10+ years of hard water stains from the previous residents and trying every internet hack, I made one final attempt to clean our shower glass using this product. The results? Amazing! I combined this with a scrub pad on my cordless drill and 1 hour later we had gleaming, clear glass again. I highly recommend GlasWeld for its effectiveness and ease of use. There were several areas I had to treat more than once, but I think that was due to the age of the stains. The stains are gone, the appearance of the glass is clear, and the product worked the same from the beginning of the bottle to the end. The GlasWeld, a good scrubber, and clean microfiber towels to polish with are the ticket!

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

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.
