I clean roofs , havent delt with vehicles and dont plan to , but I have a question , I have a 2000 mallard camper , its painted aluminum , there seems to be 2 types of finish on it , half is easy to clean and the other half has black stains over it . I have tried a mix of bleach it didnt work .Is there any cleaner that you guys use that works ? matt
