Performance can be hindered if dirt gets in any of the moving suspension parts. Use  
compressed air, a soft paintbrush, or a toothbrush to remove dust or dirt. Avoid using  
solvents or chemicals as they can actually wash dirt into the bearings or moving parts,  
as well as cause damage to the electronics.
