This is the first time in my life I have had to deal with a very visible and unattractive build up of hard water stains which I have now spent months trying many different products and so called “hacks” to remove 😫 (for example no combo of vinegar worked🤬) I’M SO EXCITED TO HAVE FINALLY FOUND SOMETHING THAT WORKS!! This stuff literally melts them away!! ✨✨ Tips on using this hard water stain remover: 1. Focus on small 1x1 or 2x2 areas at a time - don’t go for the whole door because it dries out and you will end up wasting product like I did! 2. Scrub the paste on for like 10 seconds, then let it soak in the area you are working on for 2-3 min before scrubbing again for about 2 min. this adds up, especially if the build up on yours is as bad as mine was! you may also have to go over some stains more than once. 3. I keep going back and forth on this but my call is don’t use water. Maybe a littttle to help spread it. I’m pretty sure it makes it less effective though 🤔 4. For the really tough spots you might need a scraper utility knife instead of a gripper/sponge! I think some of the hardest to remove stains on my doors were developing since the building was built over 5 years ago and the scraper utility knife in conjunction with the paste was the only way to get it off. 5. Once it’s clean definitely squeegee after every shower! I even use a microfiber cloth to touch up any remaining spots because I’m not going to let my efforts go to waste 😅🥰 cleaningtips hardwaterstainremoval hardwater hardwaterstain LTKHome
