I've had good luck with the Microfiber towels; I buy them in the big package from Sam's Club for about $12 for 20. I just recently got some from Menards with a rebate certificate, on sale for about $2 for 24. I use them for my Tack cloths followed by a good vacuum brush. Then run them thru the wash and either dry them alone or hang dry them. If you put them with other things they pick up the lint. For finish I have bought the bags of rags from Rockler when on sale. The material appears to be cotton T-shirt like.
