rags, dry, the less other use 1st the better.
Anything around (bed sheets destroyed from yrs of use, same w/old clothing, bath towels, I cook as hobby so plenty of 'dish' towels cut in 1/2, other cloth). Any kind of paper or bought stock is avoided...
At the end of each job or end of day it is more ofa thought gathering, early bill pre- bill prep (just like swep up, speedy dry, pan/pail drains) clean & put away (so as to find easily) sort of 'down time' thing for me. BUT...I take 2 'real breaks' and a long away from shop 'lunch' break too. I enjoy my self employ, food & shared timewith others~
