    Having a problem with rust. Tumbled clean, rinsed with hot, final rinse with hot water and inhibitor. Blew it out with clean air and set on the hot air dryer for a while. The tank is lined with light rust.

    What am I doing wrong? The only issue I can think of is it takes a while to empty the tank of media.

    Thanx

    Is it a steel tank? If it is, it's flash rust.

    Did you try to rinse out the inhibitor before drying? Global now recommends that you skip this step and dry directly after dumping out the diluted inhibitor.

    why on the hot air drier? If you just blew it out with the cold dry air from the tanks should be sufficient if the tank is warm/hot from the last rinse. No need to blow hot air into it after that.

    Realize it's flash rust, but there's a lot of it. Didn't rinse the inhibitor. I will try skipping the hot air.

    Thanx
