Try bleach and TSP (trisodium phosphate -- sold at paint stores). One soak overnight, and EVERYTHING comes off. I got a whole whack of Grolsch bottles once, and some were pretty bad at the bottom. 24 hours in bleach and TSP, and all that crud just melted away.

The commercial version of this is Diversol (also called "that pink stuff" by most of my homebrew friends) which at my LHBS is 4 to 5 times as expensive.

This is the one time I've used bleach. A little bleach in water, soak the bottles overnight and in the morning the mold is dead and gone. Of course, you rinse and rinse, and then air dry. Then sanitize as usual before using them.

This has probably been said in the thread, but bleach will do it. I know there was a thread for "useless equipment" where a bottle brush was listed as being "useless", but this is one time it shines. A little soap, bottle brush, rinse thoroughly, and into a light bleach soak. Actually (I have mentioned this in other threads) I just have a trash can with bleach solution where all 'first timers' go for a soak until I am ready. I just push them under until they fill up with solution and leave them sit. No need to worry about anything.

I use to have a 20 gal barrel that I would keep full of water and "liquid dishwasher soap", when I would finish a beer I would rinse and sink it in that barrel. When it got full I would pull the plug on it and rinse the bottles inside and out. The lables would always fall off and the insides were spotless.

Any of the above work. Mold is easily removed. However as to replacing the Newcastle bottles and green (I use Becks), I keep all I can get. I love pouring out of clear bottles and the green ones are classy when I have company. With the clear bottles, I can see exactly where to stop to leave the yeast behind and get the maximum amount of beer in my glass. With reasonable care, you will never have a skunked beer. I always bottle some in brown for picnics and such but mostly use clear when I have them.

The way I see it, if you've got 48 other bottles that are usable, it's not worth your time and effort to scrub mold, dude. I've been there. 48 bottles is 2 cases of beer; a whole 5g batch. Screw the 12 moldy ones, man. You'll get more I'm sure.

Agreeing with Pumbaa on Oxyclean. This past summer I kept a cooler outside and kept a rotating flow of bottles going thru an oxyclean soak. And there were some HIDEOUS bottles as well. 24 to 48 hour soak, labels fell off, took a bottle brush only once I think, then rinsed and boxed and they are ready for use.

Make sure you rinse 'em really well after using oxy tho...

I soaked the ‘original 12’ over night, only to wake to see significant accumulation of precipitation here in N Texas and be told to work from home! It’s a good thing I didn’t throw them out after all. I also found @ 12 more that needed additional cleaning after the fact.

So now I have @ 24 to deal with? Keep them or toss them out?

Keep 'em. A little mold is nothing to worry about. Soak in bleach solution as other have suggested, or get a little fancy and use PBW cleaner. Either way, I would suggest purchasing a Bottle Jet.
