I purchased a Sidekick aluminum trailer in mid-July that hadn't had an acid wash for a while so along the way home, I had it washed at a truck stop.

It really made a nice difference and my friend that went with me said his sister had bought a trailer similar and that the second wash really finished it off even nicer.

I don't any close truck stops that offer that service and along the way going on my vacation they'll be a truck stop I could have it washed at. 

How often do they recommend to have your trailer acid washed?  Would it be too soon again?

Thanks!

If you are in a location with your trailer that will allow you to wash it yourself,then,that is what I'd do rather than run it through a truck acid wash.

I dont like commercial acid wash facilities for trucks because I want to know what I am washing my own investment with.Plus,I am certain that I can get all of the chemical rinsed from my roof and around my windows.I have seen acid wash from commercial bays run down the roof and from around the windows on the sides of the trailer and streak them to beat the band.

I use a product called Streakmaster to wash mine.Sure it is work,and takes a while,but,I'm just fanatical about my "stuff" in that way.MetalWax also makes what I understand to be an excellent group of products with a flouride wash,although I have not had the opportunity to try them out yet.

As some more learned posters on HTW will probably tell you,the oxidation that appears on aluminum trailers,particular the "mill" finished ones,is a natural occurance that is inevitable to return in a matter of time.I follow up my acid wash with a protectant that I also wash on/rinse off and that seems to retard the graying process.Good luck.

PS: if you had it washed in mid-July,why would you want to have it done this soon? Just sayin,I think that's too often,myself.

I dabble in the streak Master products and occasionally use Purple power from HD.

I like the Streak Master products best.

I dilute the black streak remover 4 oz to a gal and wash the whole trailer.

Then wipe the non-polished aluminum running boards wheel wells and roof line using a a sponge to avoid drips and runs with the Streak Master aluminum bright (be care full with this stuff)

And after a good rinse I finish off and following washes with the Streak Master Ultra Guard.

I do the heavy cleaning twice a year (Spring and mid to late summer) and then just regular scrubbing with the ultraguard.

I too love a clean trailer.
