I've been lurking for a while, but I've encountered a problem with
which I wondered if anybody here might be familiar. I am
refinishing a couple of wood bowls that came to me with wood stain
and varnish of some sort on them. I removed the wood stain and
finish without problems, but the bowls have stains in them resulting
from use. One of them particularly has a dark stain on the inside
side I'd like to remove or lighten. Has anybody successfully
bleached or otherwise removed stains (probably oil or grease based)
out of wood that has been in use for a while? Any tips or
suggestions for doing so?
I have developed a method for refinishing these types of bowls which
gives me results I find pleasing. I like working with tung oil
which is probably not dangerous but not specifically labeled as
foodsafe. I apply several coats of tung oil to the outside of my
bowls, and apply a couple or few coats of mineral oil to the
inside. I replentish the mineral oil every now and then as needed.
It has the advantages of being food safe, (used for medicinal
purposes so definitely safe taken internally) relatively
inexpensive, easily obtainable and mineral oil does not support a
bactreria colony as readily as vegetable oils.
I hope somebody has a suggestion or two on removing or lightening
