Motorcycle exhaust systems can become quite hot. In fact, they’re hot enough to melt certain types of material. Over time, the exhaust pipe metal can be covered with one or more splotches of plastic or cloth burns. These burns usually don’t respond to a regular cleaning, and will need some special care.
As well as the fact that there should never be any deposit on an exhaust pipe in the first place, the bold angles of a high performance sport bike are sure to be marred by a piece of melted plastic on the pipes. When getting a cleaner, be sure it’s a high quality one that won’t damage the actual exhaust pipe structure.
Always be sure that the cleaner is rated for use with a carbon fiber or chrome pipe, depending on the type that the bike has. It may be a good idea to initially test the solution in an inconspicuous spot, as with any type of cleaning solvent. If the deposits don’t readily come off, the job might call for scrubbing. It may be wise to use a cloth wrapped around a wood block to aid in cleaning.
Be sure to avoid scratching the metal while doing this. Make sure that there are no nicks or scrapes being formed while cleaning the motorcycle exhaust. If done correctly, the deposits should come off after a period of time.
Since prevention is the best medicine, there should be some effort to avoid burning things onto the exhaust pipes. It’s obviously impossible to always prevent this from happening, but leaning objects or body parts against the pipes of a bike that’s just be ridden is just asking for them to get burned. That’s a good way to get hurt, as well as create deposits.
