He He, while in my detailing guide I tell people to just use a towel, I use a wash mitt. Towels still work better but I have used the same wash mit for 3 years and I have become quite fond of it. It is a sheepskin mit and is very soft, never had a problem with it. Towels often can hold more water and are cheeper, either will work. Buying the right mitt is not easy, there are many ones that are bad for your car and can be prone to scratches.
The key thing no matter what you use is to make sure it is always free of debres, keep dunking it in a bucket, keep it clean. It is best to have a second bucket to dunk it in before the solution bucket to get the most possible off.
