(1) good rinse with boiling water removing most of the sludge
(2) half fill with very hot water and add a couple of scoops of oxyi
(3) remove airlock from screw top lid and replace with solid bung
(4) up end and prop against garden wall , then go and get a coffee
(5) 1/2 hour later turn fv right way up and leave for 30 min or so
(6) Give it a good wipe round with cloth or sponge
(7) Empty and give that bad boy a good blast with power wash
(8) Have a good nose round inside with an inspection mirror. (cheap as chips on flea bay & if you run any type of keg a must)
(9) If I am happy with it then let it dry out and star san
I realise that's a bit long winded. However I am a bit retentive on the old cleaning front, and don't see any easy way to clean the screw top fvs that I use. As far as crud is concerned it gets everywhere you can & cant see, particularly in the indents inside the roof where the carrying handles are.
Finally I give all my plastic a good soak in domestos at a rate of 25ml per litre for 24 hours every 3-6 months, followed by the usually blast and finally a soak with a capden tablet for another 24 to rid the chlorine. That brings them back like new.
