Roger,
Based upon the picture it appears that there may be just the
after mass of residue from the burning and there may only be a soot residue.
I would try the following before going down the poultice route.
1.
Use a good alkaline cleaner / stripper degreaser and try
cleaning the surface first. Many times this will clean the stone and brighten
it.
2.
Test a small area honing that area and in your honing water use
a neutral cleaner the combination works well, see if this will clean and
brighten the stone.
3.
If that does not work, then go and try a poultice testing a small
area.

|
All, I
have been asked to restore a fire place mantel or surround. Please see
attached picture. The stone has been removed from the wall and is
currently dismantled. My plan of attack was to 1st poultice it with 40 %
hydrogen peroxide before using honing pads to remove any surface etches. My
question is, is there any potential problem in applying the peroxide
poultice? Or do you have any other recommendations to brighten up the stone? Thanks, RK |
