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

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.

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.

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

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

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
