steel wool is like sand paper, use it to make the surface smooth, just different surfaces require different materials
the 00000 is the fineness of the steel wool, if u use a very rough one u could expect to get a rougher surface result compared to a finer one.
Not exactly true. Steel wool 00000 is the finest form used to dig out dirt from porous wood like rosewood. normal steel wool can buy from NTUC but that one is used for scrubbing burnt food off a pan. lemon oil loosens the dirt within the pores hence making it easier to clean. you get go to HomeFix and buy both items.
cannot use steel wool sand down/polish paint on a guitar body. the roughness a little inconsistent. sandpaper the way to go. however if you are talking about matt finish, steel wool 00000 MIGHT prove to be useful in the finish department.
is the steel wool00000 expensive?
erm about polishing and the roughness part you mention.. and the cleaning of the rosewood fingerboard..
wouldnt take make it possible to lose wood while unearthing the dirt from the wood grains of the rosewood fingerboard?
no choice gotta always polish your frets each time u change strings if u dont like the oxidation. you could blame it on the high humidity singapore has or how reactive the nickel silver is to the air. get stainless steel frets, they dont have that issue, but thats another can of worms for another day.
for me i use brasso and a cloth and use masking tape to cover the board when im having a go at the frets.
