- Wavex Glass Polish & Hard Water Stain Remover 350ml | Car Polish for Windshield, Glass & Mirrors | Car Glass Polish, Works as a Glass Cleaner, Provides Optical Clarity

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. 😊

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

Decent Product

Just treated my car with WaveX Glass Polish and the results are too good. It cut through years of hard water buildup and left the glass super smooth and reflective. A must-have for car care.

Useless ..worst..not working at all to clean water spots from car at all. Whether on windshield or car painted body, its not working on any part. Not even able to remove or lighten any hard water spots from the car. You can see the images i attached of my car windows. Its after using this product as described. I even rubbed the window for almost 20 minutes after applying this product solution but all hard work resulted in total waste. Complete disappointment and waste of money.

വല്യ പ്രയോജനം ഇല്ല. Water stain still there.

I am from Neyveli... Since mining is done here the ashes will get deposited on the glass... So when i wash the car the water gets reacted with these particles and form hard water spots over the glasses... I used colin, vinegar, etc. to clean the class but nothing gets done... These spots will be visible in night if a vehicle comes from the opposite direction and u ll get blind out... I had renault pulse previously and water spots got deposited on those glasses... So i spent Rs 4000 for removing those stains from the glass using a machine.... Initially it was good and for about one year there is no stain formation. But after that gradually it started to form stains and its a great headache... And initially i bought my xuv 300 and within 1 month i got those hard water spots in this car also.... So i decided to go for 3m ceramnic coating.... Since my budget was tight i postponed that thing and i searched for some cheap solution to try out myself... And finally i saw this... But without any hope i ordered it... But finally the results are.... Awesome😍 its just amazing product.... It removed those stains effectively and at the same time it feels like it will detach ur hand too... Becoz u need to work hard to remove those spots... And again.. it works like nothing else in the market i have tried... And u ll see a smile after using this product.... And finally i am seeing my sunroof again in my car like a new one... 😍😍😍Thumbs up👍keep it up WAVE X.... I ll purpose all ur car products soon... Tland Thanks a lot.. In the image i after cleaning

Nice product! It works well and removed the water spots after applying polish twice. Definitely a value-for-money product.
