Yep, Medium Density Fiberboard, a.k.a. Sawdust HELL!Ahhh, I see... Now you know how "handy" I am... or rather how handy I'm NOT!Medium-density fiberboard, I believe. One of the few things I was able to take from all those home improvement shows I used to watch!Oh, and what is MDF?
The sawdust is like talcum powder, or the dust from sanding drywall. I was using a skill saw, and a router. Working in the driveway, but forgot to close the door.
I pulled the bikes out and hosed 'em off tonight, then spent an hour with the shop-vac cleaning the rest of the garage. Looks 200 times better now.
