Don't think there's a jet wash, organisers willl need to see if the owner can provide one. Failing that there is a stand pipe in the camping field, some one could always bring a hose (thats what we do at Billing).
Having said that, the last day we were there it was only me, a 90 and a disco thats go bogged

, I drove throught the lake and got mine cleaned out

, t'other 2 drove home as was
