Sick of that ugly blue tint that’s ruining the gleaming shine of your motorcycle’s exhaust? You’re not alone. Motorcycle forums are full of posts from motorcycle enthusiasts complaining about ‘why are tailpipes turning blue’ and want to know how to remove bluish from stainless steel. It is a common and very irritating problem.

It is mainly caused by heat penetrating from the inner wall and through the body of the exhaust pipe. When it hits the chrome surface, the heat causes it to turn blue. Fortunately, there is a simple way to get rid of it, and the results are impressive. This is how you do it.

Essential steps to repair blueing in motorcycle exhausts: how to fix motorcycle exhaust

Here’s how to remove blue from chrome pipes.

  • Remove debris and dirt

In addition to the blue discoloration, you most likely have a lot of dirt and debris in your motorcycle’s exhaust pipes. This must be completely removed before you can continue.

However, don’t be tempted to use harsh chemicals to clean your motorcycle, no matter how dirty it is. They could damage the chrome and make the situation worse. The same is true for high pressure water sprays, so don’t lose them.

Always wait until your motorcycle has completely cooled down before starting. Rinse it with cold water to remove most of the dirt. You can use motorcycle shampoo and a soft cloth to remove any remaining dirt and grease, but do not drag the cloth along the surface as that will cause scratches. It’s important to take the time to remove every last drop of dirt at this stage. Rinse with cold water.

  • Dry and dust the exhaust

Before proceeding, the exhaust must be completely dry and free of dust. To do this, you need to invest in a microfiber cloth. You get what you pay for here. More expensive fabrics have more fibers and perform better, so it’s worth spending a little more on them to get a high-quality product. Use only one section of your microfiber cloth at a time. To do this, you need to fold it in half and then in half again. This gives you eight surfaces to clean, which is enough to remove every last speck of dust from your motorcycle’s exhaust.

For this stage, you need another microfiber cloth. Put some polish on a microfiber cloth and gently apply it to the exhaust pipe. Then rub it into the chrome in small circular motions. Don’t try to rush this. You need to work in a small area at a time. Focus on one square inch and fill it in before moving on to the next. Use a clean section of the microfiber for each new section.

Continue until you have covered the entire exhaust pipe.

Finally, you should use a clean microfiber cloth to polish the pipes. This removes the last traces of enamel and perfects the finish. Some people like to re-wash the exhaust with motorcycle shampoo before final polishing.

Aspects to consider about bluing

There are a few things to keep in mind about this process.

This process will work best in cold conditions so the pipes don’t get too hot. Do not attempt this work in direct sunlight. Move your motorcycle in the shade or preferably to a garage.

  • Use only liquid polish

Powdered polish will not work for this job. It is abrasive and will permanently scratch the chrome on your motorcycle’s exhaust. With repeated use, it could completely remove the chrome.

The chrome polish works by removing a thin layer of chrome from the top surface. Therefore, each time you perform this procedure, your chrome layer becomes thinner. So this is a job that should only be done from time to time.

Sometimes it is not possible to achieve the perfect results. You may find that the chrome has been completely burned out and the blue color you can see is the nickel left over from the chrome plating process.

  • Chrome is an option

If you are not satisfied with the appearance of the exhausts, you may have the chrome applied again.

Some owners prefer to cover up the problem. Plastic or chrome liners are possible options. They are available in many shapes and sizes and can look great. However, they will not prevent the bluing and when you remove them, the problem will still be there.
