So i was trying to clean the scum that the krausen left around the top ring of my carboy and was having some trouble figuring out a good way to scrub around there. It was at such a weird angle i couldnt clean it well enough with a wire brush so i started to do some brain storming.
That is when i got the idea to buy some of that aquarium gravel and put some of that in the carboy with just enough water to swish it around. I then just capped the opening with my hand and swirled the gravel around and BAM! clean as a whistle. I was so excited i thought i might share with you all. I probably am not the first person to think of this but figured it might help someone else out as well.
