When sanding between coats of stain or top coats of polyurethane, I generally used very fine (220 grit or finer) sandpaper. I would be interested in feedback on whether or not using 3M or Norton synthetic steel wool could be used instead.
Thanks.

I don't have specific feedback as to effectiveness of the abrasion qualities. Do a dozen or so test pieces using different finishes, different sanding pads/paper/wool, ScotchBrite pad (also, maybe?), etc. and see what works best for you and/or for a specific test project.
Regular steel wool is not recommended for oak, as the fibers, that may get stuck on the wood, will/may react with the tannins, in the oak wood, and may cause black spots to show up, later. There's other woods whose tannin or resin can react in similar scenarios, also, just not as bad as with oak... unless some other factor is also introduced, somewhere.
Each is inexpensive, so I wouldn't think that should be party to the determining parameter(s).

Sonny, thanks for the feedback. It looks like I have some testing to do.
I was aware of the steel wool / oak rusting issue and that's part of the reason I like the synthetic steel wool. It's not a cost issue but rather just that I find the synthetic steel wool easier to work with and it creates far less (saw) dust.
