Re: stop wasting money on lemon juice
alcohol works but it is a very strong degreaser, i honestly dont know how it compares to vinegar as a degreaser but i think i remember hearing that it is stronger at degreasing.
and what is bad about degreasing? well on brass its not a big deal because just a new layer of oxide (patina) forms and seals the metal but on steel it will allow it to rust and rust on steel will continue through the metal.
and fyi watch some of those words, they are taboo here
