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..

from kegland website:

Materials:

Food grade PET

you cant brush plastic especially not with bristles. and especially not a fermenter.

you will cause micro abrasions and or outright scratches which will
a) hold the perfect place for bugs that you wont be able to get to.

and
b) cause fogging ( just go to any aquarium with round tanks they are all fogged up from scratches) which will prevent you from seeing if the FV is actually clean or not.

a soft cloth brush may work but you definately dont need to get inside that thing.

from the chubby manual:
DO NOT use caustic soda or strong acids, as they will deteriorate theplastic material of the tank
DO NOT use steel-wool or abrasive scrubbers.For scrubbing protein residues, use of soft sponges is recommended

Cleaning and Sanitation1. For cleaning, we recommend non-caustic products such as sodium percarbonate or our Atomic 15ABC (Alkaline Brewery Cleaner P/N 9006).For easier cleaning, we recommend our Fermenter Cleaning Kit (P/N 8051ND).2. For sanitising your Chubby Apollo, it is best to go with non-rinse phosphoric-acid type sanitisers suchas the Atomic 15 Foaming Sanitiser (P/N 9001) or something similar.3. Do not use caustic soda or strong acids as they will deteriorate the plastic material of the tank.4. Do not exceed temperatures above 50°C. PET is a soft plastic and will deform at higher temperatures.5. For scrubbing protein residues, soft sponges are highly recommended.DO NOT use steel-wool or abrasive scrubbers.


i thought the whole point of the chubby and why they say not to ferment in there oxebar 20l is because you can get your hand in the chubby. you must have big hands. lol but seriously cant you get a kid or someone with small hands.

i still would use the softest cloth.

i ferment in oxebar 20l's. i cant get inside there. theres a lot of threads on cleaning plastic PET without brushing.

i find a long several hour soak with oxyclean gets it spotless. and works even better than short PBW blast which cant be left in contact with PET too long or will eventually cause issues.

@Keruso I take it all back.
And I would take it back.

That's going to be a bugger to keep clean
