That's fine then. A lot of "cotton balls" are impregnated with perfume, or lanolin which dissolves into the isopropyl alcohol and then dries on your lens when the alcohol evaporates.
I only ever did that once and it was many years ago. My 8" mirror looked like a snail crawled over it continually for a month in every direction. It took a lot more isopropyl alcohol and lint free cotton to get it off. Never again. I have since sourced a good supply of lint free cotton which I use to clean my mirrors and larger optical surfaces and I use good quality double ended cotton buds for my eyepieces and binoculars.
