Well we finished seeding on Monday May long weekend and now we are cleaning up. In the past I have always had a Deere Cart. But this year we bought a new BG 7960 cart. My question to you guys who own steel tanks. Do you wash the inside of these things. I know my Deere was plastic but everything else that wasn't plastic would rust all to heck. Now I'm a little scared with this bourgault. I paid a fortune for it, like to keep it in good shape. Any advice on washing and cleaning steel tanks.
