Use a neutral detergent to clean the crank arm and the bottom bracket. Using alkaline or acidic detergents may cause discoloration.
Do not wash the bottom bracket with high-pressure jets of water. Water may enter the bearing section and cause noise or adhesion.
The gears should be periodically washed with a neutral detergent. In addition, cleaning the chain with neutral detergent and lubricating it can
be an effective way of extending the life of the gears and the chain.
