i just used dish-washing liquid...Ajax I think.
Washing in a dishwasher also works fine (washed two caps - the one for 37-116 and for 20). Thought of doing this one also but then the dishwasher was already loaded with dishes.
The only thing, there was some grime on the shaft it that only was removed by lacquer thinner. When it got on my hands, no soap, nothing other than the thinner took it off. Not even GoJo.
I then took a long-bristle high quality brush and brushed inside while in the detergent. It is easy - 20, 70 and 90 have huge caps with large gaps between vanes.
Oh...at some point I realized it would work better if the rotor is removed so I took it off...it's a snap. Assembling it back is also a snap - take about 1 minute.
the 70's cap has two spring contacts in the middle instead using bolts to the body to connect to the rotor.
