Yes, you will have to clean your truck bed bike rack regularly if you want the best performance out of it. Cleaning your bike rack should be done carefully since almost all truck bed bike racks are made from metal and other corrosive materials. That said, cleaning your bike rack is a walk in the park and should take you a few minutes. All you need to do is to get some soap and water then clean it with a damp cloth. You should remember to dry the bike rack well to ensure that it does not start rusting. It is not uncommon for people to forget drying down the nooks and crannies such as the bolts, which ends up causing rust to the whole equipment. Regular cleaning will also improve the life of your bike rack so that you can enjoy it for longer.
