Auto cleaners had more clean, lower-lint rags and towels around at that time.
What I need to do is learn my microfiber cloth quality levels. Telling good from bad, cheap from good etc is something I cannot do yet.
My father always used a smooth lint free cotton rag to remove wax. I still prefer it to microfiber. However I still use microfiber and agree with you on finding good ones.. I like the costco ones so far..
