To get the most out of your MRP chainguide or bashguard, and ensure years of reliable function, it is important to take care when lubricating and cleaning your bicycle and drivetrain. There are several solvents, chemical compounds, and other materials commonly found in lubricants and cleaners that can be detrimental to the polycarbonate found on many MRP products. These include:

- Mineral Spirits
- Propane & Butane (sometimes a propellant in canned lubes)
- Acetone
- Ammonia (in some cleaning materials)
- Benzene
- Hexane
- Kerosene
- MEK (Methyl Ethyl Ketone)
- Turpentine

“DRY” lubes often contain solvents as delivery agents and are frequently the cause of premature failure.

Exposure to “citrus” degreasers will dramatically reduce the life of your guide or bashguard.

Common signs that harmful products have been used include:

-Failure without attributable impact

-Small, fine cracks around fasteners, reliefs, and seams

-Plastic that has become brittle over time

If your MRP product has these symptoms it is important to replace all the polycarbonate parts at once. Additionally, it is critical to carefully clean all drivetrain components to remove all potentially still harmful residue. Failure to do may result in product failure and potential injury to the rider. Use of caustic lubes and cleaners voids any otherwise applicable warranty.
