Hi, does anyone have suggestions for nuking/removing bio-accumulation from all my stuff?
I want to do a big clean, my carboys are in p okay shape but one or two of them have those light films that may be mineral deposits or who knows what. I am going towards big mouth plastic carboys, but still have some glass ones, theyre the ones i mean because i can’t really reach inside and the long carboy brushes just arent perfect.
thoughts, like an acid solution or a certain technique with PBW or what? i have on hand alkaline wash solution or whatever its called
I have generally relied on overnight soaks in hot (just water heater hot) PBW at the normal concentration to get my my glass carbons clean when they get beyond “normal” dirty. Nothing special, just time.
I have a three vessel system with pumps and a HERMs coil in the HLT. Every two years or so I do a deep deep clean with Citric Acid Powder. I use a pound in ten gallons of water and heat to 180 to 190 degrees. I let is soak as long as needed to cut the beer stone and other build ups. I run this though my pumps and coils as well. I use a mesh filter to catch what ever is flushed out. I transfer the wash to my glass carboys if they need it. (Works on kegs as well,)
I repeat this with a home made PBW mix that soaks to ensure the citric acid is nuetralized, followed by flush with hot water. I also sanatize the lines and carboys with Starsan.
This process takes me two days so I only do it after about 30 to 40 brews.
If I clean after every brew day it sure keeps the crud away!
One of the brewery wash products is a good first step. I like to perform a full 140F flushing with the wash products and 140F water rinse. Having a RIMS makes this simple.
