I live in a rented house where the plastic countertop (probably from
the 70's and 80's)
is badly stained. The landlord will not replace it. I was wondering if
I could somehow clean it.
Regular cleaners including comet cleanser doesn't do much. I was
wondering if using an orbital buffer would be more effective
especially with a more abrasive cleanser.
Can anyone recommend something more abrasive than comet for my
application?

Clensers like comet will take the finish off whatever you use them on. My
recommendation for your problem is Barkeeper's Friend. It is a polishing
clenser with bleaching additions.



barkeeper's friend is simply oxalic acid. it is not a polish, is not a
cleanser, and has no bleach additions.



I recommend household bleach to remove food stains. It is
non-abrasive and won't scratch or dull the surface. You can "revive"
a dull countertop using an auto polisher and successive abrasive cuts
made for autos. This can make a mess, mask off areas using newspaper
and masking tape.
