Any chemestry experts out there?

Is there any chemical that will disolve soft, rotten wood without disolving the hard wood surrounding?

That would be SrrBB1
Soft Round brass brush

Been there, done that! Need something that will get into areas that a brush can not.

What about using (carefully) a small pinpoint torch to "burn" out the punky areas,keeping a can of water close to stop the action then clean out the burned out areas with compressed air and dental picks

I know what you want to do and I want to see the results too! A sandblaster and a little experience will do that - to some extent. More so than a brush but not the hidden ends, nooks and crannies.

Perhaps not a chemist but an entymologist? leave the blanks in a termites nest and maybe they will munch out the punk wood first an leave the hard stuff kind of like leaving bones and skulls next to a red ants nest done that in in Africa and in the morning they were clean (O the things Ive done!) also here in the UK we have somthing called wood louse I think a translation is may be pillbug over here they eat rotten wood any way find one an insect with a taste for it even perhaps a millipede

Have you tried using a 0degree tip on a powerwasher? I have removed wood from my siding with one.

Don't know what you are trying to accomplish.......would dental picks work??
