Clean Your Aluminum Trailer In Just 7 Steps

Cleaning your aluminum trailer is almost easy as cake. It is like cleaning any other vehicle, but a bit more delicate. Here is the 7-step process of cleaning your aluminum trailer along with the list of things you will need. 

Things you will need 

  • A long broom. 
  • Mild dish soap or aluminum-safe cleaner.
  • A sponge.
  • Microfiber cloths.
  • Garden hose with a spray nozzle or pressure washer. 
  • Bucket (If you don’t have a garden hose).
  • Aluminum polish or wax.
  • Gloves and safety goggles.

Step 1: Brush Away The Dirt And Debris

Start by brushing away all the dirt and debris outside. A broom will come in handy at this point. 

Step 2: Give The Trailer A Good Rinse

When you are satisfied with the dirt removal, give the aluminum trailer a good rinse. A garden hose does the job in a few minutes. If you don’t have one, then a bucket will also do. 

Step 3: Spray On Some Aluminum Cleaning Solution

Put on some mild dish soap or aluminum-safe cleaner in a spray bottle. Spray onto your trailer. If you have a hose attachment, this job gets done a lot easier. But a bucket filled with water and cleaner can do the same thing with a bit of time. Make sure to cover all areas.

Step 4: Scrub Scrub

Give it 2 or 3 minutes. Then start scrubbing with the soft bristle or sponge. Scrub thoroughly all over your trailer.

Step 5: Clean Water Rinse Again

When all the scrubbing is done, rinse the trailer with clean water. Make sure to remove all the soap and foam.

Step 6: Dry Your Trailer

The aluminum trailer is like a clear glass, if you leave the water on it after washing, it will stain. So make sure you dry it out with a microfiber cloth

Step 7: Wax, Polish, And Protect

Use an aluminum polish and wax to protect it from other damages. And you are done. Do not skip this step as leaving the trailer on its own will damage it. Also, it keeps oxidation at bay. 

Safety Tips:

  • Avoid using any harsh bristle brush. Never use steel wool or anything hard on aluminum. It’s a trailer, not a cooking pan.
  • Pressure washers should have a slower setting or should be sprayed from afar as it might bend the aluminum.
  • If there is previous oxidation or stains on the trailer, an aluminum oxidation cleaner will help remove the stains. 
  • Always read the levels of the cleaner or soap before using it on your aluminum trailer.
