Electric and nitro-powered RC buggies are designed for off-road racing, but they still need to be cleaned and maintained. Dirt bike racers and ATV riders routinely clean their rigs because they know that rust, corrosion and buildup can cause performance problems and even breakdowns if left unchecked. RC buggies are no different and should be cleaned after every driving session.
Remove the body and use an appropriate wrench to remove the tires from the chassis. Set the body and tires aside.
Clean the chassis by removing as much dirt, dust and grime as possible. An air compressor with a blow gun attachment will do the job in seconds, but you can also use a paintbrush with thick bristles. Simply brush away dirt and grime with the paintbrush. A toothbrush can be used in tight spaces and to clean the various nooks and crannies around the chassis.
Brush away dirt from the exposed ball bearings with a toothbrush and then move on to the shocks. Pay particular attention to the springs, rod ends, shock shafts and shock seals. These components should be completely dirt free.
Spray a liberal amount of Simple Green on a rag and then wipe down the chassis and all of the suspension components. If you do not have Simple Green, submerge the rag in soapy water and wring out as much water as possible before wiping down the chassis.
Spray WD-40 on the suspension arms, axle carriers, shocks and shock towers and the bottom of the chassis. Wipe the excess oil off with a rag. The WD-40 will lubricate the suspension pins, bearings and other metal parts and give the plastic components a lustrous shine.
Pour a few drops of liquid dish soap into a bucket and add water. Use a scrub brush to clean the tires. Submerge the scrub brush in the soapy water and scrub away as much dirt as possible. Use a rag to dry the tires. Never submerge the tires in water.
Spray WD-40 on the tire side walls and wipe the excess oil off with a rag. This will give the tires a nice shine and condition the rubber compound to prevent cracking.
Use the scrub brush or wet rag to clean the body and then dry it off thoroughly.
