condensation or hot load

What commodity?
Are you talking to the water that sticks to interior walls and never seems to want to evaporate when you need it to?

 

I worked for a carrier that always seem to put me on a load that required a food grade DRY trailer, following a frozen load. I had extra towels with me. I’d wrap those around a push broom and wipe every thing down, except the floor. It worked pretty well. I’d then put it 60 continuous for the 35-40 minutes it took to get to the shipper and it was good to go.

 

Needlessly to say, I’d get some funny looks from drivers seeing me do this.

 

Yeah that's what I was going to say. In a pinch I've used my clothes to dry the walls off when loading onions. It's a rare occurrence for me, I generally know my next move ahead of time so I just leave doors wide open some place overnight.

 

After a washout to dry out run reefer on coldest setting continuous for an hour than check. Before getting loaded. And keep doors shut.
Cooled air is dryer.

 

Cold air is drier,but it can backfire on you if you’re somewhere with high humidity. I do ltl,mostly frozen and some days I could take a shower in the trailer after the doors being open for a few minutes.

 

Shut the doors while cooling.

 

I use to get a washout before I would go pu paper,run it on 40 continuous trust me on this one.
