Can someone give me some good tips? I had a small oil leak (which I fixed) from the inner primary, but before I got to it, oil had blown back and deposited a light coating on the bottom of the muffler. This oil then proceeded to sort of "cook" itself onto the chrome, and I can't seem to find anything to take it off, short of scraping/buffing, which of course will ruin the finish on the muffler. Does anyone have an idea of how I can get the "caked-on" c--p off the tube?

 

Many of the chrome cleaners will work to a point, but, I would recomend Easy Off oven cleaner. It works to help remove burned boot soles etc... from pipes, so, it should work for the baked on oil. Good luck.

Thanx much Neil, and a great idea!! rmack

 

I'd pull the muffler off, that oven cleaner can be bad on paint and other surfaces it could get on from overspray. Just my opinion.

 

The 3M brand plastic scrubber pads (several varieties) are great at taking off stuff that gets on or even slightly pitted into chrome. They are very abrasive against all foreign matter but their Brinnell hardness rating is far below good chrome. Try some aerosol NAPA Brake & Electric Motor Cleaner with the pads. Almost nothing that is petrol based can withstand the NAPA cleaner. Go easy at first on a test area in case the chrome is crappy.

 

try some acetone with a soft cloth

 

oh, if you get hooked on using the aerosol Brake and Electric Motor cleaner on parts and stuff, don't ever get it into a mechanism that has to remain lubricated, like a clutch cable or a bearing or a friction point of contact cause it has zero lubrication value and will dilute lubricants badly.

 

I agree with 1mrbill.
Pull the muffler and don't get that stuff anywhere on your paint or the engine or frame.
Oven cleaner will PERMANENTLY DAMAGE ALL surfaces it comes in contact with.

 

As weird as this sounds, in restaurants and foodservice, vinegar is used to "Deglaze" baking pans. Without knowing exactly how burned on it is, get the muffler warm-to-hot, saturate a coarse cloth or 3M green scrubber with distilled vinegar, go with a back-and-forth motion (wear an oven mitt). This also works for Asphalt pebbles if you get stuck by a roadwork zone. D-Kay
