Pressure fermenter cleaning

[Keruso]

Hi,
I recently purchased some kegland chubby 30L fermenters from MM. I’m currently serving my first brew using one. I added the dry hops shortly after high krausen, cold crashed and then started to server from my kegerator. Excellent beer, but interested in how you clean the fermenters ? I can’t get my hand into it, seems it would be tricky to get a brush in them too, I have the usual suspect cleaners, Oxy, PBW, and Enzybrew, what are you hints ? Thanks

Something caustic. Can you really not get a brush in?

It's really only a bent loo brush, and I have been using this type of brush for years. Imo the best crud remover out there (funny that )... And a bit of pipe stuffed on the end, makes them reach into the deepest drum, FV, kettle etc..
