Poorboy's World Spray & Rinse

Results are great...But as a few have already pointed out, use with care.
I've used it many times with great results. Really cleans well as a spray and go. Never used a brush since it seems to really clean well.

I purchased this product based on the mostly positive reviews. The product does work and removes brake dust well. However, you do have to be very careful when using it, because it is acidic. The label recommends gloves and protective eyewear, which is good advice. I was using the product in a 1:1 water dilution; I wear prescription eyeglasses, and when spraying my wheels a couple of drops splashed back onto my glasses, and burned a hole in the lens. So I had to order a new pair of glasses. I had fair warning from the label, so I am not complaining, I'm just saying the label is correct, and you should have all skin covered when using the product, and use protective eyewear.

Also, the sprayer deteriorates after a couple of uses and does not last long, so you will need to order a chemical resistant sprayer if you order the product.

So the product does work, but it not something I am able to use safely and will probably use non-acidic cleaners instead.
