The ordinary job and the one most bags are. Sorted by colour and by how hot it can go, washed, tumbled, folded and bagged.
Forty five a kilo, weighed wet on the step in front of you, with a two kilo minimum so a single shirt does not cost a rider's trip. The scale is a trade scale and it is checked every six months.
What we sort out before washing: anything with no care label, anything already stained with something that sets in hot water, and anything that is going to lose its colour onto everything else. Those come back to you with a note rather than as a surprise.
