Just thought I'd share my cheap alternative to one of those fancy expensive sponges that goes between the lug nuts of the wheels.
Daiso is amazing! I tried it out today and it worked like a beaut! Good for 4 rims and discard the sponge. For 2 dollars it comes with 5 sponges.
The sponge is super soft on the white side and the orange side is just a little firmer. It got right in between and got out those little spots I could never get before. Also there's no way you can scratch your rims with the plastic wand.
Share your cheap alternatives people.
