Cleaning old poly coated wood trim
I know the trim is coated with polyurethane, but 20 years of grease, cigars, and probably old wax needs to be cleaned off. Trim is oak with an unknown stain (wood looks yellowed.)
I tried scrubbing a small section with Dawn and warm water. The sponge was filthy and it seemed to dull the area. Is this a safe way to clean the wood?
I'm hoping to avoid having to refinish.
