I have brown spots all over my muffler on my R50. Anything I can use to get them off?

you have to simmer it (cook it) in anti-freeze for a couple hours, then it'll wipe off

You could also try boiling it in bio detergent

Some oven cleaner is caustic, and will turn aluminum black. Stop using the castor oil fuel, and you won't continue to get spots.

If u must use fuel with castor, then perhaps u could use a muffler which is black in colour. I saw a few helis in a magazine as well as on RR which had those on. Although I've never seen a hatori and certainly never a mp2 in that particular colour. Also perhaps there is some coating which u could do on ur muffler. Still, like Al says the easiest thing is not to use fuel with castor in it.

The boiling in antifreeze works very well. It also cleans all the crud out of the inside of the pipe as well as the outside.

Super easy with metal polish. Just make sure you can use it on aluminum.

Years ago when I was involved with the local club, someone donated a ultrasonic cleaner, and at the time you could buy a engine cleaner from the hobby store that was made for this purpose, cant remember the name of the cleaner though, but with the ultrasonic cleaner and that engine cleaner in there throw the engine in, and when it came out, Im not kidding it looked just like it was when it came out of the box when new.

I just soak mine in Simple Green overnight...works like a charm and something just seems wrong about boiling antifreeze!
