garden hose with high pressure fan tip, DAWN and a rag :lol:
How long does the black last? have you had mud or rain cause white spots?BUT....in all seriousness, If it's really muddy I go to the car wash and wash off the heavy stuff. Then I go home and wash the it with No. 7 Car Wash Concentrated Powder and finish the outside with Turtle Wax Ice spray and the inside with Ice interior spray. The exterior spray brings the black back and doesn't turn white.
