I've been using Mirlon (www.mirka-usa.com) as a substitute for steel wool. It a non woven abrasive scuff pad sold in woodworking stores that is available in 360, 1500 & 2500 grit. Sort of similar to Scotch Brite.

I primarily use wet or dry abrasive paper but something like steel wool does have its place at times & I find Mirlon works much the same as steel wool w/o leaving particles that shine or potentially rust behind & you don't need to degrease it.

I especially like it for knocking the gloss back on some types finishes.
