I was referred to this product by a guy that details cars. I just bought a new BLACK car and as we know streaks and marks stand out on black. Not to worry anymore! I used this product right after purchase (be sure to soak it in warm water as instructed before use for a few minutes and wring it out good) and it worked much better than any chamois that I have ever used. Super absorbent and no streaks! Just wring it out as it absorbs and you will have your car sqeeky clean and streak free in no time. If it is dirty afterwards ,,,, again wash it out in warm water ,,, wring it out and store it in the container while damp. Will last a long time. Machine washable if needed .....and at this great price maybe you want a couple of them. I'm gonna buy a second one because I am SO impressed. Buy one now,,,,, you will NOT regret it. My new black Lexus looks like it did when it was delivered to me...sparkling.
