I am about to buy a house which has a garage with major oil stains all

I am thinking about cleaning the floor with muriatic acid. Then I
intend to paint the floor with a couple coats of patio concrete deck
paint.

Does anyone have experience with this. Will the paint hold for a least
a couple years? Are the stains likely to show through over a couple
years?

Thanks for your input,

Sounds like a recipe for disaster. Muriatic is not a cure-all or
clean-all. It won't eat acid, but eats concrete. I would try some
kitty litter to suck up oil, a couple of applications. Have never
tried, but would not entertain thoughts of painting oily concrete.
