Wash Up Wiz Net Scourer 5 "Works well and washes like a hanky." 17 February 2020 I used to save food net bags to scrub with, because they wouldn't clog. These are much better! And they’ve been fine in the washing machine. They've emerged fresh, with no loss of size, crispness or colour. I checked with the manufacturer - after the event - and they said yes, it's the easiest way ...which was a relief! I think they’ll be immortal.
