Steel Wool rusting?

Hi, I'm applying matte water-based polyurethane to my douglas fir table.

Up until this point I've been sanding between coats with steel wool, BUT, I just read that this is a bad idea, because the steel particles can get trapped in the finish and eventually rust. Yipes!

It's still too early to tell, so I will proceed as usual without the steel wool.

But has anyone had this happen before, and how bad was it??

If so, should I sand back and start over at this point?

Yes. This is a real problem that many people experience. To avoid it just use a synthetic version of steel wool.

Thanks Ttharp,

At this point it's too late to avoid it, I just hope it won't happen.

To embellish: I'm looking for advice on whether I should sand back and start over .... or just keep going and hope no rusting occurs.

Cheers,
Jill

You might want to sand the top back as it's what shows the most

If you've finished the piece I'd redo when the problem occurs

Cut it twice, measure once and it's still too short.

Unless a person was wet sanding between the coats and exposing the steel fibers the steel particles wouldn't rust suspended in the finish but I wouldn't want any particles of anything in the finish if I could help it. Steel wool is a poor product for between the coats because you are suppose to be leveling the finish and steel wool will just rub over bumps in the finish instead of taking them off. You need sandpaper for that purpose. Still, the grit comes off sandpaper and can get in the finish so after the sanding is done the surface needs a thorough cleaning before going with the next coat.

I certainly wouldn't start over. I would just suspend the steel wool and keep going with the finish.

I wouldn't leave remnants of steel wool shards on the surface, or embedded in the surface. I would sand back and do a thorough job of dust removal. Instead of steel wool, I prefer to use an 'open coat' sandpaper. I use it with a block on flat areas.
