When you notice that the broom isn’t enough to wipe off the dirt and grime, it’s time to switch to a high-pressure hose. Now spray high-pressure water on the trailer bed to remove caked-on debris.

Make sure to not spray water frequently on wooden regions as this can cause dampening of the trailer floorboards, which can lead to needing a replacement. And to be honest, a replacement wouldn’t be cheap.

Step 3: Prepare An Acid Bath to Remove Grime

What Is the Best Way to Clean An Aluminum Trailer?

There are a lot of ways to clean an aluminum trailer. However, finding the best method for yourself could be quite time-consuming and tiresome. Also, no one wants to go through the hassle of trying out all the methods and then finding the best method for themselves.

So, what is the best way to clean an aluminum trailer?

Well, you would always need to wipe it off using a broom or washing using high-pressure water. However, when it’s time for deep cleaning, you need to get a mild soap solution to help in removing everyday dirt and grime.

If your aluminum trailer is painted, then use soap for a car wash that would eventually retain the paint’s gloss. Apply pressurized water from the hose and then use a long-handled scrubber to mop the soap solution, then finally rinse.

How Do You Get Oxidation Off Aluminum Trailer?

You’re probably wondering that once your aluminum trailer gets oxidized, then there’s nothing you can do. Oxidation of aluminum is similar to corrosion, where aluminum reacts with oxygen in the air to form a thick layer of aluminum oxide on the surface.

However, it’s not impossible to remove oxidation from your aluminum trailer. All you need is a good old solution of hydrofluoric acid or any other decent brand of citrus cleaners. Spray along the oxidized region.

The cleaner cuts through the aluminum oxide and removes oxidation. Then gently mop off the solution with a scrub brush and wash using hose water. Make sure to wear gloves during the process as acid or cleaner solutions are corrosive.

What Can I Use to Bring Back the Shine on An Aluminum Dump Bed?

Everybody loves shiny metal vehicles, and you’d be lying to yourself if you said otherwise. Like any other metallic vehicles like cars and trucks, your aluminum trailers also deserve the bright white shine of a polish.

Over time, asphalt can build up on the surface of the metal, making it difficult to achieve a uniform shine. But cleaning asphalt out of a dump truck or trailer doesn’t have to be a struggle.

Now the most effective and efficient method of doing that would be to wax coat your trailer. Coating the trailer with wax protects the exteriors and, most importantly, also prevents oxidation.

Applying paste wax takes its time to apply correctly, but the results would definitely be worth it. It gives the aluminum surface the signature it deserves.

How Do You Clean A Black Aluminum Trailer?
