Sponge Debate (3.0) Anonymous 108466
I believe, Abrasive Sponges, are the best for removing tough stains. This applies to cleaning dishes as well as the house in general.
This cant possibly work for stains on regular walls
for stains on the wall you can use a magic eraser/melamine sponge
Getting one of these changed my life. They last longer than the sponge in the OP.
They also look much happier.
I wish I was that sponge
OP here, I will admit that does put a smile on my face.
