This is one of my most interesting topics because frankly I can not stand black streaks.

I ran out of my streakMaster product late summer.  Worked my way thru the last of my Purple power and stored the large LQ for the winter.  Knowing all along I really haven't given it the final fall cleaning I like to.

I went to reorder a gallon of SM the other day and nearly fell over to the price increases. 

I had a thought reached under the kitchen sink and did a quick spot test and would like opinions.

I tried glass top stove cleaner on a small area. the black streaks came off in one swipe the area polished to a shine.  Now that was easy.

Anyone else ever try this product?

it's more/less a pumice product,I use it myself on my own glass top stove.But glass is not the same as the thin coating of paint on the aluminum walls of trailers.You'd be better off using baking soda if you want a polish type cleaner,but,even with a heavy hand,baking soda can scratch.

I have used 409 before with pretty good results.it cleans up most anything with black streaks,patio furniture,anything with white or light colored rubber base,especially tire whitewalls.but it didn't completely remove them,because,there is black etched into the paint on our trailer on close inspection.I think waxing and polishing with conventional good grade car products is about the only thing to remove it to become almost unnoticable and help the quick return of black streaks.That's why I love my all aluminum mill finish other trailers,just wish my LQ was the same.
