What is the recommended salvage technique for soot staining on unfinished wood surfaces?

The recommended salvage technique for soot staining on unfinished wood surfaces is sanding. This method is particularly effective because unfinished wood tends to absorb soot, creating a stain that can be difficult to remove through washing or other superficial cleaning methods. Sanding allows for the removal of the stained top layer of wood, effectively eliminating the soot that has penetrated into the surface.

It’s important to use a fine grit sandpaper to avoid damaging the wood and to ensure a smooth finish afterward. Additionally, sanding can prepare the wood for any refinishing that may be desirable after the soot removal. In comparison, options like washing may not penetrate deeply enough to remove the soot, and polishing would not address the underlying stain. Brushing may help remove surface particles but will not effectively eliminate deeply embedded soot. Thus, sanding is the most effective and recommended technique for this specific scenario.
