We moved our washer and dryer to the basement from the 1st floor and
the two front foot pads from the washer left what I thought was rust

solutions? Thanks,

Look in cleaning aisle for 'rust out' or similar product. Works pretty
well on the rust stain under the drip in my 2nd bathroom plastic
shower stall. Don't remember what the main ingredient is, but I think
all of them are similar products. Make a paste of the powder, and let
it sit awhile. If the stain is into the substrate, you may be SOL.

oxalic acid.
