How to Remove Bluing From Motorcycle Exhaust Pipes
Bluing on motorcycle pipes is caused by extreme heat. (Motorcycle exhaust image by Crisps 85 from

Motorcycle exhausts can become covered with a blue or yellow discolouration that cannot be removed with a thorough application of soap and water. This staining, which is called bluing, is caused by a reaction of the chrome or steel exhaust pipes and the intense heat produced by the engine. Bluing removal products, such as Blue Job or Blue Away, can be used to return the motorcycle exhaust to its original silver colour.

  1. 1

    Wipe the motorcycle exhaust down with a rag that has been soaked in soapy water. Use a motorcycle approved soap, which can be purchased at automotive and motorcycle supply stores, instead of household soap in order to prevent any residue.

  2. 2

    Dry the exhaust with a soft cloth.

  3. 3

    Apply a thick layer of the bluing product to the motorcycle exhaust. The product may come in a cream form or a powder that must be mixed with water to form a paste before application.

  4. 4

    Rub the bluing product into the exhaust with a soft cloth. Use small, overlapping circular motions and apply pressure in order to completely remove any traces of bluing.

  5. 5

    Rinse away the bluing product with cool water.

Tips and warnings

  • Apply the bluing removal product again if there are still traces of discolouration.
