Removing shellac from old furniture

[Max1ne]

Hi. I have used meths and wire wool to remove dirty, old shellac from a footstool with turned legs. It has left a black residue of dirt in the grain which is proving difficult to sand away (because of the awkward fiddly shape & the fact that it's ingrained). Is there an easier way to clean off this residue? Do you think sugar soap will do it?

You could try oxalic acid (wood bleach), Liberon do one

Thanks. I have already bought some sugar soap so will try that first. If it doesn't, I'll give oxallic acid a try.
