black spots on exterior after removing cover
Need a little help. We just removed the cover off our Alante 29f today and the exterior walls had dark spots all over. I washed the motorhome with an automotive car wash prior to putting the cover on it two months ago. I found a spot that was not too conspicuous and tried numerous products, (409, bleach, scum remover, and dawn platinum) to remove them. Dawn platinum worked with a hard scrubbing, but I read that dishwashing soap shouldn't be used on the sides, only the roof. Has anyone run across this problem and if so, were you able to find a solution? Any help would be greatly appreciated
