it is wonderful product

Nice quality,It actually vanished the old stains including water stains which was not cleared after washes.

Average!!!! Not Good Five more time used no Hard water spot Removal Hard water spot is not deep in my Car .. But It mostly useful only for Chrome grill and Headlight visibility.

Very useless product there is no effect on the glass

If you are purchasing this product i assume you have hard water stain,oily residue,some kind of gunk when wiper is working under light rain(bonded contaminants). I would say that it is not that good for hard water stain. But this product gave me very good result on the first try itself on my other issues, yes definitely a arm workout if you dont have a polishing machine.For hard water stain i would recommend Q4 HARD WATER SPOT REMOVER. For rest of the issues WAVEX is great. DO IT WHEN YOU ARE NOT IN A HURRY MAKE THIS LIKE A ZEN ACTIVITY. I saw loads of comments say it dint work for them, so let me expalin what i did, clean the windshield and wiper with car shampoo throughly leave it with soap for like 3-5 mins then repeat it one more time told you a zen activity. Then wash it off, dry the windshield with microfiber cloth. Then apply a generous amount of the product (whenever required)to an applicator or a microfiber cloth i used applicator, rub the liquid in a circular motion and just keep rubbing till your hands give up leave it on for like 5 mins, after take little more of the product and start rubbing it again till your hands give up. Leave it take some rest take , later take new microfiber cloth a dry one clean the windshield vigorously applying pressure, at this point i did not care i was doing a circular motion or not ZEN activity my rear. Any way i rubbed the product clean with a microfiber cloth clean and washed it off with little water the started the wipper blades. Washed the windsheid again with generous amout water with wipper on so that wipper gets cleaned out if any product remins.And the with a pressue washer. The windshield was as good as new. As told previously had used Q4 for Hardwater stains. Did it in late evening so that i could see the difference immediately. If you have read this till now i genuinely hope this product helps you as it have for me. Thanks Happy and safe driving. 😊

Good

This is not as effective as expected. Very light small stains are removed but harder stains are not removed. I have tried multiple coats and used this mulriple times but it couldn't remove the stain. I bought this specifically for hard stains so this is of no use for me now.

As the zen guy said in another comment, the product does works. The hint as to why simply applying it and rinsing it off doesn't work is written on the packaging itself in the "facts" section - "... If not cleaned quickly, even from glass, water spot minerals can etch into the material and leave permanent marks that will not come out ...". I tried leaving solution on the glass and even scrubbing hard with a cloth but that didn't work at all. Then I tried scrubbing the glass with a scrub, this time it did work but left scratches on the glass :( Finally I found the trick - adding crystallized salt to the solution and scrubbing hard with a sponge in a circular fashion - this worked perfectly and removed all "permanent" water spots! I think the product itself should admit this need for hard scrubbing or provide such coarse powders/crystals or atleast request users to use salt in addition to the product.. So yeah, it isn't gonna be cake walk because the water spot minerals are absorbed into the glass/surface and some sort of coarse powder/crystals are needed to break those bonds. The zen guy was right after all but why not use some tricks and skip the zen part :p

Useless product

good product works very well
