I use paper towels for interior clean up and it works just fine.
Wait for the towles to go on sale somewhere like Kohls o Linens & Things. I got some big bath towels for only $6ea. Also, some hand sized towels for car wash mitts for $3ea. Just gotta be patient for those, o you pay $15ea for a towel. I recommend two towels for one vehicle at a minimun. Often times you'll use one to dry after a wash, then another for Z6 while the other one is drying.
As for the microfiber towels, I have heard mixed things. Some have nothing but praise, others they create scratches. Cost just as much as towles so I'd just get towels.
