cleaning a trailer
 

can anyone tell me what i can use to clean up an aluminum trailer(you know that oxidation type stuff that builds up on it)I have tried pressure washing it but that didnt work.ANY IDEAS??

Try WD-40 and a wire brush...let the WD-40 sit for about 5 mins or so before you scrub...

Like reel said!
I know it does sounds strange.
After you get the trailer back to the shape you want, you need to then do some preventive maintenance.
The outer protective coating has been lost, allowing oxidation. My favorite preventive covering for aluminum is spray silicone.

i would agree...get a wire wheel on an angle grinder and go to town.

Well, a wirebrush and WD will work for sure, but that's a lot of elbow greese. Buy some Naval Jelly. The one for aluminum, not metal, spread it on with a paint brush, let it sit a while and then just hose it off. Viola...all done... (I like the chemical way because it gets into and cleans the pores of the aluminum.) Then either spray it with silicone or clear coat it with polyurethane. :beer:

Where do I buy naval jelly.Never heard of it!

I was going to say navel jelly also, stuff is great!! can get at most hardware stores walfart use to carry it also

Didn't know they made NJ for aluminum...like the way that sounds...I was thinking of the polyurethane finish, too...will that hold up?

i have an al trailer that is 12 year old and i have never done anything to it, i just refer to the coating as "patina". thats what the antique people do, makes it worth more.

Go to a powerwash supply store and buy a product called "alumna-Brite". It will clean the aluminum without etching it. Made for cleaning alumium siding you can use a pump spayer to apply let the solution soak and powerwash off.
