High Quality Bulk Microfiber

I don't use the yellow mf from costco any on the car's finish any longer as they really seemed to leave micro-marring on the car's finish.

I tend to use the cobra towels for wax removal and buffing. I use the Eurow o'Reilly fluffy blue towels for day to day detailing.

I will use the yellow mf towels for dash or interior

 

It would be the other way around 70/30 is for the paint, it is a softer towel. You use the 80/20 for interiors.
