How can i get rust out of my trailer? In spots it is quite deep. Thanks

Answer
The right way is to sand blast it away.

Another way is to grind it out.

You said trailer...is it an aluminum trailer--as in tractor trailer...if so, you can use acid made to clean aluminum (it can also be used to dissolve rust on metal).  Call a local tractor trailer outlet.
