you should rinse stuff with cold water after "washing up" stuff
as hot water & say Fairy Liquid creates the suds
where as cold water creates less suds and rinses it away so to speak
(not quite true but there is some merit in the above)
Also very hot water will fuck up certain types of plastic bottles etc.....
best use luke/hand warm water to rinse and be done with it
btw - what's with this sterilisation stuff ???
as long as bottles are not heavily tainted - fuck it just rinse a few times with water
(top on - give a fucking good shake, rinse/repeat a few times - job done for me)
if it is really heavily tainted with something then use another bottle
(use that one bottle for that tainted flavour in future, so to speak)
sod this overthinking malarky
