Use Simple Green you can buy it at any autoparts store for 5 or 6 bucks but be sure to mix it with water 50/50 mix i think. you really should have to cover anything up just make sure that your wires are on your coils tight. Then for a nice shine i like to use Mother Bullet Polish on the Chrome and wipe everything down after all the water has dried up. This is what usually works for me. Also try this
