I have an old table that I tried to clean up with Howard's restor-a-finish (walnut, because that's what I had) followed by some feed-and-wax a few months ago. I realized later that something brown is rubbing off the wood. The first clue was that an envelope I left sitting on the table developed some oil stains. I rubbed at it with a bit of cloth and that came up brown. I tried rubbing it off but it just keeps coming. I assume I used too much restore-a-finish when I was cleaning it up?
What's weird is that I no amount of rubbing seems to take it up.
The question now is what to do.
I tried buffing out some of the brown, but it just keeps coming. If I rub a cloth on it picks up a lot of brown, but only with pressure.
I tried letting it sit but months have gone by and it clearly isn't going to just dry.
I tried using Murphy's oil soap and hot water, which definitely took some up, but I still haven't gotten it all up. I could keep changing the hot water and using Murphy's but is there a better way to clean up this mystery oil? Turpentine? Rubbing alcohol? If I use linseed oil on the table, will it seal it or just make everything worse?
