I figure while I cant drive the car, I mise well clean it up. Whats the best way to polish a chrome air cleaner, valve covers, monte carlo bar, and export brace? Also, My Edelbrock Alluminum Performer intake has gas stains, like yellowish brown. How do I get them off? Also, My nickle plated (I believe) Holley 650 is dirty. How do I clean it? These are all brand new, just have sat in the garage for a while. Thanks for your help......
