I think it just takes a few weeks of WFP to get the knack. I'm 6 weeks in,.. and every day my feet are staying a little dryer. I've still not perfected the technique yet,.. but I'm making progress.
Stand further back,..
Stand off to one side,..
Turn the pump down a bit,...
Work faster (Dryer!) after all those 1st cleans are done....
It all helps
