Gtechniq W9 Water Spot Remover for Cars, 500ml | Advanced Solution Easily Removes Stubborn Water and Silica Spots from Bodywork, Suitable for Glass, All Paint Types and Vinyl

I got recomended this from a colleague at work for removing pesky water marks that appear after I clean my car. The water gets trapped in awkward places and ends up leaving water marks on the freshly cleaned car. This stuff makes it effortless to remove the water spots, leaving the fresh, clean paintwork on show, rather than a streaky mess! It sprays well and covers a nice area, meaning you don't have to use loads of it to remove water stains. You simply apply it, wipe it down, then go over the area with a clean microfibre cloth and the jobs done.

Does what it says on the tin, great product

Sadly this product did not get rid of the rain water spots on my car paintwork and made no difference at all.

Trying to be clever and washing both family cars at once seemed like a good idea at the time. Any married bloke will probably know why I attempted this and during the winter I'd likely had got away with it... But anyway, my car started drying before I could get to it, and the bonnet ended up covered in water spots that flatly refused to budge no matter what I threw at them. Enter the Gtechniq W9 Water Spot Remover. I've trusted the brand before, and at £16 for 500ml it's not cheap — but I figured if it did the job, I'd happily pay double. Spoiler: it did the job. Just don't expect a spray-on, wipe-off miracle. This took me a solid 30 minutes, a thick microfibre towel soaked in the stuff, and repeated buffing of each affected area before the spots finally surrendered. My arm was aching by the end. Worth noting that roughly a week had passed since the spots appeared, and the car had been sitting in full sun, so your mileage may vary depending on how fresh the damage is. I've included a video — it's a bit rough and ready (turns out buffing and filming simultaneously is harder than it sounds), but it shows the product working in real time. End result: bonnet looking as it should, lesson thoroughly learned, and next time the wife's car can wait its turn.

Worked amazingly well. Cleared off the several weeks old water streak running down my side mirror on my red Mazda

Didn't really notice it working

DOES EXACTLY WHAT IT SAYS VERY PLEASED

A great seller, excellent quality of your products, brand new, and the appearance is great, and great value for the money. The delivery service was excellent 10/10. I will definitely be buying from you again.

Works well for me. I highly suggest to spray this onto a damp microfiber applicator and then rub it onto the surface. Especially on glass. Spraying directly onto a spot on a panel kind of concentrates it where it lands unless you have a quick hand to wipe it in. Great water spot remover for the price.

Great product but pricy

Had mixed feelings about ordering this to remove the water spots on my black pickup truck. I hadn’t realized that water spots were common after putting on a ceramic coat. But before spending hundreds of dollars more having it professionally detaiyto remove the spots I figured I’d give it a try. I first washed my car and towel dried it, leaving the surface slightly wet. I then applied the product and rubbed it in a bit (helped quickly) and finally buffed it out by hand with a thick microfiber towel. Came out beautiful. Lastly, I washed the truck again with chemical guys ceramic foam soap for ceramic coats and then thoroughly dried the truck. My truck looked like it was as fresh as when I initially had it ceramic coated. Needless to say I’m pleased with the product :)

Smells like straight vinegar....it works on light water spots, but i doubt it'll work on them multi layered waterspots.

I love this product between washes to keep my paint spot-free. It’s only meant for removal of LIGHT water spotting BEFORE it etches into your vehicles paint. Anything that’s too deep will require polishing/compounding. Don’t listen to reviews from those who say it doesn’t work - they believe the product is magical and can remove all spotting which just isn’t true.
