Don’t have one. Sponge so much cheaper. Plus I did the dishes afterwards. Two birds, one sponge.

I used a Scotch-Brite heavy duty scrub sponge. It’s made by 3M and can be bought in singles. This is a very easy cosmetic thing to do. The most time consuming part is masking the iPhone with tape. For that I’d suggest blue painters tape. It left both the glass and plastic residue free.

might use those for round 2, but Double-Sided Sponge had been training for months for this event and I didn't want to disappoint him.

I wouldn't recommend it because i haven't tried it, but if you go to luismayhem's youtube video you'll see that some people have already tried that and it seemed to have worked out alright for them. No guarantees, though, and no pics so far.

I'm guessing that would just restore the chrome finish, though, and I'm not as fascinated with chrome as Apple is. I don't think this tip is for everyone, but I definitely found it interesting enough to try.

I just used a simple kitchen sponge for it…really not that coarse, although by the end of it there was an indentation on the sponge where the green stuff came off 😛 If you're gonna do this, I suggest really taking your time with the strokes so they're nice and straight.

sandpaper would likely do the same, but it might be too rough. I was really just following instructions and then posting my results and pics here.
