I have recently purchased an older home and have had to do some
plumbing work. In order to access the upstairs plumbing, I've taken
down the entire kitchen ceiling. It has exposed the plumbing in
question and some evidence of minor water leaks - nothing recent.
There are some small mold spots on the wood under the tub, but they
look old and dead. My question is, would spraying the wood around
these areas with white vinegar kill any mold that might still be living
there? Nobody is living in the house yet and probably won't be for
several weeks while I finish this work so the smell isn't a major
issue. Also I'm considering one of the tea-tree oil products like
Hygienic Aire or similar to place in the furnace return ducts and just
allowing the fan to circulate the air for a couple of days. Are these
good ideas or wastes of time/money?
