"Back in the day" I never used one, prefering instead to use solvent and pa rrafin on my chains. But these days I use one of those boxes and find it wo rks fairly well. They're still available for sale.

... anyone remember those from the '80's. they were a chain cleaning box thing, with the internal brushes. just add the fluid, hang the box on the
chainstay, give it a few swirls, and viola ! a clean chain.
