| okay this may sound totally crazy but it works. you know the discoloration you get on your slides , that black stuff, well a really easy way to get that stuff to go away is to get an eraser and then erase it. make sure that the grease on your slide is off and try to use a softer eraser not a hard one. it sounds crazy but it works , don't push on it hard just do it lightly. i wasn't totally sure where this should go so i figured that it could fit here, anyway happy erasing!! |

You could use sandpaper, too.
Seriously, the valve clearance on a good trumpet is about 0.0005”. An eraser is abrasive. Use the eraser several times and you can take off a couple of thousandths without noticing.
A better way is to get some muriatic acid at your local pool supply store. Mix a mild solution (30%) in a glass (that’s GLASS, not plastic) deep enough to cover just the valve section, not the spring box, an insert the valve for 30-90 seconds. Rinse thoroughly.
Wear gloves and eye protection and do it outside and you won’t have any trouble.
I’ve used the mild acid on a bunch of vintage horns with blackish-green crap on the valves. Works great.

If you decide to use muriatic acid, read the label precautions carefully and follow them! Muriatic acid = hydrochloric acid = strong acid = chemical burn hazard.

You can buy it at a hardware or pool supply store and he did say to dilute it. Be safe -- wear gloves and goggles. If you don't like acids at home, don't look under the sink. You probably have plenty of them there in all kinds of "cleaning" supplies.

Arrgggh!
I forgot to mention- For several reasons, if you are diluting acid, add the acid to the water (rather than adding water to acid).
- If you're not an adult, I strongly urge you to get the assistance of an adult before working with anything hazardous. Make sure they read and follow the label precautions, too!
Hazardous materials can be handled safely if proper precautions are taken. Your home probably has several hazardous materials, follow the label precautions when using any of them.

First, let me say, I don't own a gun ... (we are way off topic here). Although some might say listening to me play is like being shot 
Second, I would believe the same thing for guns. Store them in a gun safe. Use a trigger lock. They have a purpose like acid, and like acid can be VERY dangerous if misused. So can liquid plumber, rat poison, a carving knife, a chain saw, gasoline for your lawn mower, even your car as a multi-ton 60 MPH projectile.
Safety should be taught and adhered to! Diluted acid is better to clean with than sand paper or steel wool which is abrasive (but also works). If you are uncomfortable with it, OK, then take your horn to a shop and have a professional do it.

| Isn't a guns purpose to be dangerous??? You use em to kill people thats the purpose right. Muriatic acid if used carefully is not all to dangerous and is highly unlikely to kill you (don't drink it) if it works use it much better than using abrasives that will cause problems down the road. |

Another somewhat crazy way to get the slides and sometimes the valves a little bit smoother is to use something called GOOP (yes, that's all capitals). I believe it is a non-toxic detergent you can get at the local grocery store that's also good for washing chemicals off your hands. I've used it on my slides many times with great results and using it on the valves seems to work okay as long as you flush your horn out afterwards. Just another thought.

Careful on that one! I have a tube of GOOP in the cupboard that is superglue, not detergent! (Not saying there isn't such thing as GOOP detergent, but the stuff in the cupboard is holding the plastic on my wheelwell in the Toyota together, so it ain't gonna be good on your slides!

Nope, I definately own a big tub of GOOP, and it's a detergent. However, seeing someone use the "other" GOOP on their slides would be quite hilarious if you didn't say anything first. Definately worthy of the Stella Award  .
