This is a very easy way of maintaining your rim or alloy dust or particle free.
First spray the wd40 and wait for 5 minutes let it soak in to those particles that dont wanna move . then grab the soft cloth and remove the dirt particles
Apply the wd40 again this time use a cleaner cloth, use waxing and polishing circle hand move till it shines
Only thing you have to do now is once a week or so just use warm water and soap to clean your wheels , the particles will hardly stick to your wheels because of the unique wd40 . this spray can be found in any 7-11 or autoshops
