Tell me where are you brewing so I can make sure I steer clear.

That reminds me of an element we wrote-in in the periodic table in high school: Smegmanium
Highly unstable!

I have to admit I was a little confused in what was happening to the bottles here wth smegma!
Lmao built like a pencil!

All I can say is wash immediately and often until the gunk is gone.

Craftmeister alkaline cleaner.  It cleans better in cold water than PBW does in hot water.

I've got another better bottle giving me a problem, and this isn't doing the trick either. The stuff is stuck like super glue. I'm on my 3rd soak and have barely made a dent in it.

I never have a real issue. If I need to, I can have a better bottle cleaned in < 20 minutes. My normal routine is about an hour, sometimes two.

I'll add a bit of powdered dishwasher detergant to the oxyclean soak, it seems to help.

Are you having blow-offs where all that gunk ends up pasted to the top of the better bottle? I've used them for 5 batches now, and 3 of them cleaned right up no problem. Two of them have been ridiculous multi-day clean-ups with several soaks in several different solutions.

I'll try it -- thanks.

I get blow off every time. I ferment 5.5 gallons in a 6 gallon better bottle.

1 - add some hot water and shake the crap out of it to get some of the low hanging fruit.
2 - fill with hot pbw or oxicean. I use oxiclean. I add about the equivalent of 2 scoops of pbw. Let sit for an hour
3 - dump all but a quart out. I will stop from time to time to shake the crap out of it.
4 - jam a soft cotton cloth into the bottle and shake and swirl it around to get all of the surfaces.
5 - rinse well.

As always make sure to rinse well.
And try and avoid the scented ones.

Same deal -- 5.5 gallons on a 6 gallon better bottle.

I'm using basically your exact method. (Either you or someone else posted it earlier in the thread.) I'm on the 3rd or 4th full cycle with the current bottle and have only now almost gotten everything. Maybe the hefeweizen yeast that was in this one is just particularly sticky?

This summer, I found hefeweizen yeast (WLP 380) to be more difficult to clean from the shoulders/neck of my Big Mouth Bubbler--and again when I re-used the yeast to make a dunkleweizen. So, yeah, maybe the hefe yeast is part of the issue. But a little extra rinsing and wiping took care of it all.

I just had the same issue with a couple dry English yeasts... stubborn stuff, never seen anything like it!

When all else fails, I've found that a lye solution is great for eating organic deposits on equipment and tubing. Just be very careful when handling. Use rubber gloves.
