It seems to get dirty fast! And we are thinking of selling it and going back to a stock trailer. But I will have to still use it in the meantime. I used to wash the stock trailers out about once or twice a year when the creek was high (drive through really fast back and forth..ha ha) and take a garden hose to it. But with solid sides it gets dirty fast, especially the side that we tie the horse too and where the exhaust comes out on the truck.
What is the best way to wash a trailer and keep it looking decent?
