Yea, those ones Chalker uses from Screwfix. I've tried others, but the dye comes out of them. It would be great if they just produced a white version of them.
Might need to try those ScrewFix ones, I have used the detailers for a good few years now & they are fantastic cloths, need to price them again in Costco.
microfibre from screwfix, bulk bag of 50 cloths and I just wash them out when I'm done. They last for ages and I also use them for polishing the van etc
