Pumice problems

Q: When using pumice stone and linseed oil to rub out slight discoloration in an inlaid dining table I encounter little spots forming. The discolorations do disappear.
A: First, if you must use pumice (and there are far better alternatives), pair it with a non-drying oil such as mineral oil, not linseed oil. As for the spots, if they are tiny and in the wood pores, it simply means you are packing pumice into them. You can remove it by scrubbing with a soft bristle brush and wiping.
