I guess it will work like a rubber, or eraser for pencils.Quote:
I don't understand the benefit of the polymer block.
It will break down in smaller swarf and take the dirt out of the "pores".
There is a similar product for dirt on walls in germany called miracle rubber (Wunderschwamm), I dunno if you guys know such thing.
I would like to try a normal eraser for that task and see if it works.
BTW. all the "high molecular weight" humbug is a chemical term for
"yeah itīs rubber, alright"
I donīt want to flame, but basically we get a pencil eraser, a wire brush and some soap?
