I have to agree with the Oxyclean posts, great stuff. Also, you probably know this, but bottles with twist-off caps won't work.
Not true. You can certainly cap them (I use a bench capper) but don't expect to get many uses (recycles) out of 'em. They are thinner walled and (in my opinion) not worth the risk -but in a pinch they WILL certainly work and I've never had one not seal.
Swing-tops -I love 'em! My favorites are the ones that Hoogstraten Poorter comes in -I really like those because you can crown 'em first, then once you pop the cap, you can close 'em with the swing top if you don't finish off the bottle (not usually a problem, but the thought is nice). One day I'll make a decent clone of that stuff. But I'd LOVE to find crownable flip-top bottles. I'd buy a case or two in a heartbeat.
