The sill cloths I wash have mud, bits of twigs, and all sorts of **** in them. Will this block up anything in my washing machine? Anyone know how to clean a washing machines fliter etc Shall I use the launderette? I wash my baby's clothes in the same machine and the missus insists I do a 15mins short wash between (with no clothes in the machine). Also, noticed scrim is leaving hairs do people wash them separately to microfibers at the hottest temperature now and then?
