I hate to be the bore in the classroom but:
Understanding what it is that you want exactly, dictates
what tool you use.
You can "screw in" a screw with a hammer.... but...
So, with "removing", not all things are equal. Otherwise we
would all be using a belt-sander with 40grit paper.
So "grit" is the important part here.
[BTW: Toothpaste is generally between 24,000 and 30,000 grit]
000 steel wool is 400 grit, 0000 is 600 and the same as Scotch brite green
Scotch brite white is 900, blue is 1,200 and black is 4,000
dry t-shirt will hold powders.... ajax is about 500-600, rottenstone (gray pumice) 900,
rouge is 1,400 and talc is 2,400.
Maguires wax cleaners and acrylic rubs are a multi viscosity and depend a lot
on what you use.... but generally 2,000 grit that can cut like 200 when used
with linen.
The grit is only a starting point.... how that "grit" point is delivered is also important.
Steel wool (IMHO) is the "instant gratification nipple for the uninformed". Grab a nail,
any nail.... go find the sample you hate the most.... forcefully drag the nail point along
the finish. Notice the "shatter" of the finish along the "line".... that is what steel wool
is doing on a semi-micro level. This will remove the gold (cut-through) to reveal the
red.. but you can also end up cutting right through the red primer and not even know
you did so.
If you substitute the steel for the same grit in rotten stone you get more of the
feathering thinning of the gold that allows the red to "glow" through, instead of show through.
A lot of times that gold is covered with a hard urethane clear overcoat..... so you have to
cut through that first.... but you also have to replace that protection after.
A damp diaper or t-shirt chunk, dipped in the gray stone, and rubbed as a paste, is the
fastest cutting as the damp will "carry away" the cut-away material. If you are doing
this on a water-gilded frame.... then you need to use mineral spirits instead.
