You must be kidding. Those yellow mfs from costco is lintsville. I use them for wheels and under the hood.backwoods_lex said:I've found that the best MF is one that is of decent quality (none of those "rags" from walmart) and clean. I buy bulk MF at costco and dedicate half of the package to windows. Wash once before ever using on a window, and wash separately after every use. I no longer get any headaches from streaking.
Black and white newspaper is also great if you are having difficulty from streaking.
