I've always used the scrub pads, but they do break down like John mentioned.
I'm also worried if scrubbing with them would be bad for smart mesh.
I'm assuming I could find one of these gong brushes at the local Home Depot. Is there a bristle type I should make sure to get? Also, how long do these last? Should I be planning on stocking up on a lot of these if I like them? Or just grab a couple for backups? Are these safe to use with smartmesh?
Gilligan, is that a "natural sea sponge"?
