cleaning black streaks

RV supply stores sell products made for cleaning these black streaks but, I use auto wax with a cleaning agent and elbo greese on my fiberglass sides. Have alse used on aluminum rv but, I would try on a small area first to see how it works. The wax will make the streaks easier to remove later when washing. Black streaks are something we Rvers fight all the time. Been thinking about just adding black stripes down mine! Think it's a thing called smog washing off the tops. Good luck

I enjoy reading Mr. Nash's replies,always very interesting and humorous.I use tire cleaner (Westley's) on the aluminun sides of my trailer with good results.Spray on dry trailer,let it set for a minute,then wash off with a sponge.Then wash the whole trailer with Zip Wax or something comparable.Remember to wash the roof once in a while,that also helps.

When your talkin aluminum sided trailers you are talkin painted aluminum sided trailers right. Cuz I just went thru a half a gallon of that 30 dollar a gal. black streaks stuff. With rags, brushes high power sprayer. It did remove the streaks dull the paint and wear out my arm. Spray on and rub off my!

I'll try that tire cleaner next thanks for the tip Will! :)

Folks,
I have a boat and an RV and both get the black streaks. On the boat I have tried Marine Black Streak remover with some success, however, the best stuff I have found is Castrol (I call it purple cleaner, cause it is a purple color). I get it at Wally World by the gallon and it can be diluted to various strenghts. It has worked on darn near everything (grease, black streaks, mildew), including my SKIN (did not remove my skin, just the stains from oil, grease, etc.) :laugh: I normally buy several gallons when it is on sale for around $4.99 to $6.99). Seriously, I use it for almost all my cleaning needs and it great.
You might want to try it and judge for yourself. Test it on a small area first to see how it works. ;) :) :laugh:

I have a 2 yr old 5th wheel with fibreglas sides. My previous trailer was also fibreglas and the 2 rigs before that were alum sided. I agree, the black streak problem is the pits. However, we have found that using Mean Green does the job. Mean can be purchased at Dollar General for $2.50 a gal, it also comes in a spray bottle. Just spray it on the streak, let set for a minute, hit it with a soft bristle brush and hose off with water. On the alum side you will probably need to use a stiff bristle brush on the streak. Used to really tick me off when I wore my arm off trying to get that streak off, tried all the commerially made stuff from Camping World/RV dealers/etc., nothing seemed to work and all it did was put a dent in my wallet.
