Hi smiles, thanks for the question it is a great one. The microbeman 5 gallon brewer is a breeze to clean. He includes a long handled cleaning brush and instructional video with the brewer. It takes me 5 minutes tops to clean it.
I'm not going to sugar coat it, organic gardening requires more effort than most other types of gardening. One thing I learned when I made my first 60 gallons of soil was that it requires a lot of elbow grease. I don't even think about it now days, but that first experience was a real wake up call. Now days it's the most enjoyable part of gardening for me. I actually look forward to getting my hands in the soil. The smell of fresh worm castings and dirt are like nature's anti depressant for me.
What's happened is an entire change philosophy, heart and attitude. I'm not an organic purist by any means, those folks annoy the crap out of me. But once I saw how my plants reacted to a natural organic living soil, it was impossible for me to go back to bottled nutrients. As you can see from my list of products on the first page, I still use a fair amount of bottles, but they are mostly for my IPM. I guess I'd say that any feed that contains salts, is off limits to me.
I've almost always got my brewer going and it's usually just got straight RO water in it. I do this to oxygenate the water no matter what application I'm using it for. I only brew an AACT once a week. The rest of the time I'm using oxygenated water for my foliar IPM/feed and as the base of my feeding routine which is mostly comprised of fish, bat guano, and humic acid. I do use a pinch of organic water soluble sea weed when it's needed. But for the most part the soil does the work for me. I could easily just use RO water the entire grow and my plants would survive. My yield and quality would suffer greatly for that, but it could be done.
I just went on an entire mind trip lol. Sorry about that. So yeah 5 minutes is all it takes to clean my brewer lol. My old brewer I called the corvette took about 1 minute to clean. It was an eco plus 3 air pump that I fed into a 6 port manifold that each had 1/8th inch tubing and those small 1 inch grey air stones. Dropped those into the 5 gallon bucket and the water looked like a hot tub. It was very effective. To clean it I'd just rinse the stones and tubing in water and drop them into a quart jar of 34% h2o2. That was about half the cost of the microbeman brewer but I did have to replace the air stones regularly.
Sorry for the confusing answer but I get all giddy when I'm talking about AACT teas lol.
