How to clean wooden funiture that has been in a house fire ?

A good scrubbing, (use a soft brush if needed) with Murphy's Oil Soap should really help get the majority of the smell... a rinse with white vinegar and water should take care of the rest.. Don't forget to use a good oil furniture conditioner to re-moisturize the wood

Start by wiping it down with a warm damp rag to get the residue off the wood. Next, wash it with Murphy's oil soap, follow the directions on the bottle, dry completely. Finish it off with Wilbert's lemon oil, buff to a nice shine, and it will moisten the furniture, so house heat won't dry it out.

Of course my go to , I know the commentators are tired of me posting it. But the best thing for wood in need is new life mask &or moisturizer. The masque actually works like facial mask and pulls out the gunk in wood pores. I think that would help with smoke smell and looks. Then moisturizer.

I agree with Marty. Murphy's Oil Soap is a great product. It cleans wood well. I use it on my kitchen cabinets and my interior doors. I love how it makes wood shine.

I would use Murphy's soap and a sponge outside on a sunny day, then when they they are clean I would use Room Shocker with them all in the same room..... https://www.biocidesystems.com/article/get-rid-of-house-fire-smoke you can buy on Amazon

The go-to for painters when they encounter "smokers walls" is to use TSP or TriSodiumPhosphate.
