CLEANING KRAUSEN FROM BROWN PLASTIC BOTTLES

Recommended Posts

I do what most people here do and rinse my brown plastic bottles immediately after drinking.

I have noticed on some of my brews that during secondary fermentation I get a small 3 mm krausen ring on the bottle.

The beer is carbonated and tastes amazing especially after 6 weeks in the bottle.

So will soaking the bottles overnight in a percarbonate solution remove this Krausen?

I don't want to use a brush on the plastic bottles in case they get scratched.

What are your thoughts?

Seriously though, I'd use a very diluted vinegar which will loosed the krausen,empty, then soak the bottles in water for a couple of hours before using some percarbonate

Is the krausen ring up the top on the neck of the bottle? If so make up a mixture of the sodium percarbonate, pour some into the bottle, put the cap on, give a good shake and then invert the bottle so the krausen ring is submerged and leave that way for an hour or two. Empty and rinse. That way your not having to fill the bottles with the solution.
