Tetraclean Multipurpose Hard Water Stain Remover Liquid, | For Home & Commercial Use, 1000 ml

Working 💯..Long time hardwater stain removed after use of 2-3 times ......

Use it to clean hard water stains, it works, use spray bottle to spray it on stains and let it sit for 2min and donePrice could be a bit better

So here's the thing my car got those white marks from water and for that purpose only i bought it, and it worked like a charm on those marks, i haven't tried it on my wind shield yet i am too lazy to clean the car atm before spraying this.Also the container is not good or atleast the one i got leaks when i try to spray, it drizzle down the nozzle after spraying a little bit, other than that it is a good product if someone is having the same problem as me with the car having white spots, i would recommend it but be caution not all paint are same in the cars, just make sure to apply a little bit first and test it out whether or not it affects your car paint

don’t buy. this only coloured liquid. even 1% efficacy not seen. total waste of money.

Worked well on some Surfaces inside the Toilet those Stains can be remove and Clean from other detergents too.

Used for cleaning my car windshield. Very much useful for removing hard water stains

It seems to remove water marks on glass but Leaves stains , looks messy post use .

I bought it to remove hard water stains on faucets, bathroom fittings and tiles. As mentioned its very powerful, it actually removes the stains. We need to leave the solution to settle for few minutes and should scrub it off. It worked well on tiles, ceramics, stainless steel.}Please note :If the fitting is not 100% steel then it may leave acid marks/tarnish stain. Then it needs to be removed by metal polish (I learned it in a hard way 😕😔). Please wear gloves because the solution is bit powerful. You may need to wash it off clearly within few minutes otherwise it may leave white marks. Use a clean cloth and wipe it off after scrubbing.
