Wash the car with good quality car detergent and warm water, and dry it

Had rusty water drip onto my car during the entire night from a pipe above in a garage

With some warm water and car soap (and a little muscle), these bars removed all the overspray

Hard water stains are tough to remove and they ruin the look of a car

The Clay Bar did a good job of removing hard water spots and most road tar spots.

So, my thinking is to wash car to get heavy stuff off, then clean soapy water with the clay bar over the surface to smooth it out, then wax with Mothers Syn Wax using the Powerball and finish off with instant detailer where needed

Used this for part of the restoration work on my EClass panoramic roof side panels.. they were faded from the sun and caked up with hard water spots... this clay bar kit really worked

The clay bars are okay, if you do not put enough water when you use it, it will leave a yellow mark which is hard to clean.

The spray itself is pretty much just milky looking water that has a curious smell of cinnamon to it and for the most part I would say that it is rather unnecessary as water will more then suffice

Water works just as well as a lubricant for the clay, but I used what they sent me, since it was all ready to go.

Please Read-I suggest using a bucket of water or a spray bottle with NORMAL SOAPY water for lubrication (think bubbly, but not gobs of foam)If your water is too soapy the clay starts to melt, but yes, slightly soapy water does work

Water works better in my opinion to lube the bar.

When you run out of spray and still have clay left, just use soapy water water as a substitute.

Don't really need the detailing spray, soapy water works just fine

I had to get some hard-water stains out of my Black Coat... and since doing that I use the detailer alone now.

Great for getting rid of water spots and dirt

Clay is very hard when I put it in a bag and in warm water still fairly hard and breaks apart as I am rubbing it on the hood.

I found the lubricant to be an unnecessary cost, since you can put water in a spray bottle and it works just as well

My car feels like glass and it's taking off the horrible water stains!!

After claying the car, I rinse the clay with clean water then spray with its lubricant to moist it a little bit and put it in a bottle for

It works exactly as it says it works

I applied this product to my 2007 Mazda 3 (phantom blue mica) as well as
