I stopped using paper towels pretty much. I used to use the blue shop towels. Switched to these thick white towels (IDK what they are called) but they were reuseable for a few cars. Found them through Johnson's. I found that they were leaving too much contamination or breaking up. I switched to using micro fiber glass towels (tight weave, low pile) and I am not looking back. Haven't had any contamination issues since then . I was using paper towels to wipe my squeegee by the way
