Thanks.
Surprised I missed this thread. Here's some more info on what I've done.
Two things to keep in mind. Yes, oven cleaner will de-anodize the aluminum, to be avoided. Other, is that in threads on cleaning A/S trailers, Andy (Inland RV) and others warn against using acid-based cleaners which may get underneath rivets and start or accelerate corrosion.
I have seen info by other S/S owners on the Net (webpages) where they have used ZEP and other commercial products.
My reading on anodized aluminum is essentially limited. A scrub brush is recommended (I have one I use for whitewall tires, not too stiff nor soft), and lot's of elbow grease.
The problem of trailers of this sort seems to be that the finish looks faded even after washing, it doesn't reflect light any more.
For the DIY portion of my cleaning I used, first, an ADJUST-A-BRUSH
Adjust-A-Brush non-flow-thru; 10" head; with ordinary car wash soap from a parts store, and worked a good long time on the roof after doing the sides. I made it a point to never let the soap/water mixture dry. I washed from the bottom up, and rinsed from the top down using a medium spray setting on a garden hose.
The elbow grease got the worst of the bird and tree mess.
Second stage was the use of MARY KATE
Aluminex "Clean & Shine". There are two versions of this product, and I used the one specified for painted and anodized aluminum. It is a buffered acid product.
Aluminex Clean and Shine Aluminum Cleaner
I bought this through WEST MARINE, two bottles. (A third and fourth would be necessary for the belly/bottom-side as the dirt build-up can be heavy).
I worked in small sections here, being careful around windows and other areas with non-metal components. Wet, apply, wait, scrub/wash and rinse.
My wife found this to be a noticeable difference, but, I should add, our business has been house renovation for some time and we are accustomed to noticing differences others may not. It isn't a bigger change, but from purchase, it is now "clean".
The second step was the testing of other chemicals from an industrial supplier on the other thread, above.
SABRE

I tested one bad area (top curve, trailer rear, port side) and the result was noticeable several days later. Seemed to have removed "film" other attempts did not.
I have not yet tried the
Anodized
Restoration
Treatment, but it is marketed as a sort of short-time clear coat that is easily removed. I look at my sample container weekly, but am just too busy for this sort of work right now.
