Soldato
If you're using extract - heat it (it pours easier) and then use boiling water to remove the last sticky stuff from the can. Careful as it's like napalm if it's too hot!
I had the extract can sat in some boiling water for 20 mins, but I didn't quite manage to get it all out without boiling water from the kettle.
S05 gets a bad rep but I've used it for lots of successful brews. It's very forgiving of temperature fluctuations and the like- mostly because it doesn't really add any flavour...which isn't a big deal in the IPAs I tend to make
Something that occurred to me (well, if I'm honest, the guy I brew with a lot) is that if you're bottling infected beer you're inviting bottle bombs. You may want to store them in a very very very securely covered way. Just in case.
edit: I know you're on S04 but just thought I'd mention it. I used S04 for a brew recently and it's so much more demanding than S05. Despite that, it also doesn't have the best rep for really giving an english ale flavour to your beer.
The 'infected' bottles are certainly rather tight at this moment in time, they're 2 litre plastic Lemonade bottles which *touch wood* seem to be holding up ok!
I discovered after pitching the S-04, that it's very very funny about brewing temperatures. I've got my Coopers Fermenter sat in a room which is 17-18 degrees, the upper limit for S-04 is 20 degrees, my wort, due to the yeast working is sat at 22 degrees, I'm hoping I won't get any off flavours in the finished article
