I recently got some slate and shell stones in Japan (actually via a
japanese Ebay'er). The bowls they came in are pine, and some resin has
seeped out from the wood around the base of the bowls (inside and
outside). The slate stones in particular have picked up quite a lot of
resin. Fortunately, the shell stones are much cleaner, but some still
have noticable resin spots.

I've read through the various discussions on cleaning stones, but
wondered if anyone has specific advise on removing pine resin. I have
tried hot water on one or two slate stones, and this seems to melt the
resin, but a small amount remains, and is hard to polish off. I
haven't tried anything on the shell stones yet, and was wondering if
hot water would have any negative effect on the shell.

I'm keen to remove the resin from the bowls as well, obviously, so any
advice there is much appreciated.

General advice on removing pine resin includes using WD40, but I'm
reluctant to try anything too chemical on Go stones, especially on the
shell.

Thanks in advance,

Mark

Resin is soluble in spirit.

hi Joachim,

thanks for the quick reply!

do you recommend any particular spirit? metholated spirits, mineral
turpentine, or something else?

any ideas on how this would go with the shell stones?

regards,

Mark

I haven't had to deal with this sort of problem before but have you
considered using Goo Gone? Maybe you can experiment with a pair of
stones?

WD40 is as chemical as fuming sulphuric or druid-drawn spring
water. Or that terrible toxin, oxygen,

Try luke-warm alcohol (e.g. 'Surgucal Spirits' wound cleaning
agent or "methylated spirits" paint remover or degreaser) or
nail-varnish remover (acetone, CH4COH in english).

Hot water will melt the wax that has been worked into the shell,
exposing the grain (like tiny pores) on the surface. The grain will
pick up skin oil, dirt, etc, and make the stones very hard to clean.
You should only use tepid water with a little mild dish soap for
general cleaning.

But for pine resin, I would recommend spot-cleaning with a soft cloth
dipped in mineral spirits (paint thinner). After this treatment, then
wash the stones in soapy water, rinse, pat dry. Then apply one or two
drops of carnuba wax (liquid car wax) to a pile of stones, toss to
spread, let dry and then buff them.

Pine bowls??? Weird. You might try rubbing them down with mineral
spirits. Then after they are dry, finish the bowls with a couple of
coats of urethane (plastic) varnish. Then throw them away. :-)

A few drops of WD40 on your full set of slate stones (toss to mix,
then wipe off the excess) is a good treatment to keep them looking
good. I would think that would not be a good choice on your shell
stones, especially if they have been in hot water.

Cheers, Roy

Oxygen molecules can be bad for you: Think O3. :-)

Yup, that's why I've used car shampoo soap - the type with the added wax.
The white shell stones became clean and it appeared to me that they also got
"waxier".

I'd try it with denaturated alcohol (enthanol with some methanol).

Thanks all,

I managed to find some surgical spirits, which worked very well for
removing the resin from the slate stones. I used it cautiously on the
shell stones, and it was no problem. I rewaxed the shell stones with a
bit of liquid car wax, and will probably do a very light WD40 treatment
on the slate stones (the surgical spirit drys them out a lot, not that
they should be dripping in oil or anything, but some of them did loose
a little bit of sheen.

The surgical spirits also worked well for removing the resin from the
bowls. I've left the bowls to dry thoroughly for now until I consider
what next to do (and also to just see whether any more resin is going
to come out.....)

thanks again to all for the advice - I'm feeling much happier about my
purchase now that I've sorted this issue out.....

regards,

Mark

Even O2 is an oxidizer... O3 is just better at it
