Update: I finally got around to removing the paint from a few metal workbench pieces with oven cleaner. Overall, I thought the oven cleaner loosened/removed a majority of the paint from the metal. I simply sprayed the product on the metal surfaces and allowed it to work for roughly an hour before attempting to remove paint. A majority of the paint was cleared from the metal using plastic putty knife.

I wore a mask, safety glasses and gloves. The job was completed outside in the yard.

Thank you for the input!
