In my utility room many years ago, I installed a drying system. A series of stainless steel clothes lines, a dehumidifier and a fan mounted on the wall to move the air. Basically a cheaper way to dry washing quickly without using the condensing drier and much more capacity.
The rule has always been load the lines up, turn it on and just leave it overnight. Next morning everything was dry, but its a bit cooler anyway in there, so difficult to be sure things were actually dry.
The other day I had a light bulb moment...
I already have a damp meter, why not use it to test whether clothes had dried or not. A bit of experimentation suggests they show as dry within
2 or or 3 hours, straight from the washer after its spin dry, depending on material thickness. So, no need to leave it running all night.
