Chemical Guys SPI1081602 Heavy Duty Water Spot Remover, Safe for Cars, Trucks, Motorcycles, RVs, Home, Office & More, (2 Pack) 16 fl oz

Excellent cleaner for removing rust stains.

This stuff is WONDERFUL. I used it to remove very bad water spotting from the paint on my car. I also used it on a HEAVILY water-spotted glass shower door. It worked flawlessly on both.

This is an amazing product! I had some tough water spots that nothing else would touch. This is the Holy Grail of spot removers. Have to use elbow grease, however, the benefits it provides is above anything else. Excellent! A little goes a long way.

Works on not so old water spots but the much older ones it did not work at all, unless it needs a lot of elbow grease.

I love Chemical Guys products. I'm accustomed to their quality and consistency of effectiveness. I own their Pink wash and their wheel cleaner products and used the wheel cleaner to help break down some rust and brake pad residue that built up on a rim. That's a tough ask and while I didn't clean it 100% Chemical Guys product actually broke down about 75% of the grime and dust that was caked onto the rim. It also might be that I didn't put enough effort and elbow grease into totally cleaning it. All that as mere prelude...I love cleaning my truck. It's a black F150 and I enjoy washing it myself - especially on sunny days. I don't like paying $12 every time I take my truck to a car wash to get it "the works" and I'm not close enough to a franchise that has a monthly subscription that would let me wash my truck without having to do it myself. So here we are. The hose I use has some mineral-rich water. Even here in the Pacific Northwest, where our water is rather drinkable from the faucet/hose attachment, there's still enough iron and mineral density to eventually leave water spots on your vehicle. I finally put a filter on it but the water spots were definitely there and I couldn't get them off with using detailer or a standard, filtered rinse and wash. Finally, I came across another Chemical Guys product and after watching the proper way to use it, I immediately purchased and tried it myself. I'm still cleaning off the gel fully with a microfiber cloth (also a CG product) my black F150 looks much sharper and more glossy than ever before!I don't have a great before/after picture but I would clean my truck before and, after it dried, I'd see those pesky water circles - especially on my hood where water is more likely to stand after a wash. The sides were mostly okay but I had some slight rigidity to the paint coat because of the stuff hitting it on the road over time - that also seems to come off. I didn't have to work hard - just apply more than a trace of this stuff and work a single section (one door or half a tailgate...whatever works). Make sure you have a somewhat clean outside already - don't do this with some mud on or it hurts the effectiveness of the product.Anyways, it took me maybe 10 minutes to get the whole truck and the top windows applied and I came back 10 minutes later, wiped it all down and it was clean. Awesome product! Worth the $17 investment and it can cover multiple attempts from a single bottle. Do NOT dilute this - it's a direct application product, not a "mix with water" product.

Does exactly what it says, the water spots were so bad. Now that my windows are dry definitely going to do the top part of my windows.

Followed the instructions as per the video. Product removed about 60 %, but not all. I tried repeating the reprocess with a slight improvement, but still not much change In defense of the product, the vehicle is a 2003 F300 crew cab. I live in the country and we have well water. This was the first time I tried to clean up the water spots

You Guy's...OMG, this stuff really works! I live in hard water Vegas, I have low windows, and the sprinkler system water would hit my window before they adjusted it. Anyway, I had tried everything... Baking soda Vinegar, dawn, etc. and nothing worked, but when I applied chemical guys, well this stuff is a game changer! I'm 68 years young, so I have to do a little at a time, The security bars and the hedges make it a little harder. Also, looking for a tool to get to the edges. Check out my pics...The left side is the clean side, I hope you can enlarge these pics.
