Re: Cleaning older galvanized trailer
go to the nearest hardware store, and for about $10.00 to $12.00 you can buy a syphine type sandbalsting gun. You then buy a bag of sylica sand I think it is like 5 to 10 pounds in weight.<br />and cost just a few bucks. then hook the gun to a simple air compresser and stick the syphine hose in the bag of sylica sand. start spraying the trailer and in no time at all you have a like new trailer ready for paint. this works very very well and is very low cost.(very fast and simple too)
