Try it on an out of sight place or some kind of spare piece, until you
get the hang of it.
larry.
We loaned a satin-finish Steinway grand to the City of Charleston for
an event. Some idiot POLISHED IT! Everyone was stewing on how to get
the satin finish back. I had a piece of satin finished piano the
factory used for packing left over. I polished it the same way then
tried Dawn dishwashing liquid mixed 10:1 with water....Took the polish
right off and the piano looked like new! Saved a $31,800 new piano,
too!

boiling steam kettle ... even make a 'tent' so the vapor condenses on the varnish. Just keep the
vapor flowing and not 'bead' up on the surface and you will get the very best satin finish. Let dry
with the covering of very small beads of 'fog'. Finish as below (#2) to complete the job and remove
any remaining gloss.
2. If the varnish is already dried, take raw pumice & mix with mineral oil or vegetable oil make a
paste ..... and then with your clean bare hand rub with the grain until you get your desired effect.
For semi-gloss satin use 'rotten stone' for the above. Both rotten stone and pumice are available
in a "paint store".
Even "rubbed-effect" varnish will benefit from the above hand-rubbing.
Natural (tung oil based) varnishes work the best for satin finish.
Hope this helps

Steel wool should NEVER be used on anything that goes on a boat. Tiny bits
will break off and you will not see them until they turn into big rust spots
later on.
Use bronze wool. Harder to find, and more expensive, but worth it.

Your question is a bit confusing. Do you mean you wish to alter a can of
varnish to give rubbed-effect results? Or do you wish to rub out an
existing varnish job?
If the former, I'm not sure. There are flattening agents which can be added
to varnish, but I don't know if they are compatible with polyurethane-based
varnishes. If you don't require a poly varnish, Interlux and Epifanes both
make rubbed-effect varnishes which apply beautifully. Neither is suitable
for UV exposure, though.
If you wish to rub out an existing brightwork job, try the finest bronze
wool you can buy and rub lightly with a light oil, such as lemon oil or
linseed. Rub unidirectionally and don't press too hard. When the desired
finish is achieved, wipe the oil completely off the surface and then go very
lightly over the surface with a dry piece of bronze wool, same
unidirectional pattern, to even out any inconsistencies. Wipe clean with a
dry towel.
That said, I still believe it would be easier and give more consistent
results to simply revarnish the piece with rubbed-effect varnish.
Don't use steel wool--when the surface gets damp any residual steel
particles left behind will rust and stain the finish.

That'll do it alright. More than rubbed effect, it should give that bare
wood look.
