Yes, I use a fine-bristle brass pot brush, with the grain and dipped in lacquer thinner, to scrub out the old filler/stripper goop that can cause REAL PROBLEMS in the new finish, due to solvent residues. ( Remember--strippers are DESIGNED not to have their solvents evaporate quickly! ) Then, after wiping off residue with more lacquer thinner on paper towels, I dtermine if bleachiung will be necessary, then sand LIGHTLY - -just enough to remove fuzz- and start the new stain and finish application. This, I believe, is the best way to get a gorgeous finish with minimal damage to the veneer. I have never noticed any damage using the fine-bristle brush, yet it gets down into the pores and cleans them nicely. Try it on a piece of junk piano if you are dubious.
