If you're wondering (as I was) what the difference between this Gray polishing cloth and the Yellow polishing cloth is...
Simply put, there's one little word in the description of the Yellow cloth an it makes all the difference.... "Microfibre".
The yellow cloth doesn't leave a residue... where this gray cloth will leave teeny little bits on whatever you've polished (much like polishing with tissue paper would).
For cleaning fingerprints off lacquer or silver, this cloth does a great job and is better value.... but if you want to wipe down moving parts (valves or slides), you want the yellow one.
I own and use both cloths, I like them both - but they ARE different.
