I have never heard of Lancashire cloths either , they sound great though .
I have a collection of old flannels or tea towels that I use for all manner of cleaning , windows ,polishing etc etc.
old flannels are great for cleaning .
I also have some lovely tea towels , I love a nice tea towel & will buy when on offer usually in Sainsbury’s & habitat . I’m also partial to pretty cloths for the kitchen .
I know , there is no hope for me . But if I have the regular white. Dishcloths then popping them in a bowl of bleach or a Milton tablet overnight is de riguer. Other than that pop in the dishwasher . Always a clean one every day .
However my DH , will use said lovely tea towel to wipe his hands , mop up spills & basically anything. Completely disregarding the dish cloths or paper towels .
But the kitchen dish cloths are usually always completely different & should therefore not be confused with the ones used for bathrooms etc.
