I have a silver Bach but i dont know the best way to clean the inside cuz it looks moldy and stuff, its nasty

There is something called a snake.

It`s a long brush that could go through all the loops in the horn.

get a trumpet cleaning kit and it should have all the materials need to keep you horn up to snuff

take your trumpet apart and use a trumpet swab. don`t forget spit valves

Yah i know wat a snake is and incase u didnt know, snakes are really bad for a trumpet. the brush rubs againt the medal inside and it makes the metal break easier
plus brushes dont do a very good job

Snakes are designed to clean a trumpet and will not harm it in any way. The stuff inside your instrument which is green or blue is a buildup of copper oxide, which bassically means your trumpet is eating through itself. If you want to break your trumpet, leaving it to be completely corroded is a great way to do that. Get a snake and clean it out.

im telling u a snake will harm it really bad. My trumpet teacher has a friend who works on instrument repair. she tells me if i want to get it out i can do one of 3 things. I cant drop it off at the shop (which i did today) put in a warm bath tub with detergent or take it in the shower and let the water go through the bell.

well then i think you just answered your own question didn`t you? *sigh*

lolz

Ya, shoulda got it to the shop in the first place...
