Does this work for 5 gallon glass carboys?
Ryan on Apr 30, 2020
BEST ANSWER: This keg washer absolutely works with 5 gallon carboys. All of the other answers here offered great advice as well, so please read all of their great contributions for lots of tips.
What is the wash cycle time? I assume you have to change out the cleaner and sanitizer between wash and sani.
Dennis Wiggins on Apr 17, 2018
BEST ANSWER: Cleaning and sanitizing is specified on the cleaner and sanitizer product's label of your choice. Contact time varies.

The MKII uses about 1 gallon of fluid for cleaning and I can usually clean about 2-3 vessels at a session. Just make sure you dump all solid matter first. I making a hot cleaning solution (>100° F) and wash each vessel for 30 minutes.

I have never used the MKII washer with sanitizing solution but would not recommend it as it would bubble up tremendously! I would suggest mixing a separate gallon of sanitizing solution and getting a chemical grade spray bottle to spray your vessels. 5 Minutes contact time is all you need for those products.

Will this work with a fermonster?
Kyle Compton on Jan 9, 2019
BEST ANSWER: I don't see why it wouldn't work for your product. I use it for the Big mouth Bubbler, Which has about the same size top as your Fermenter, and for my Corney kegs and buckets. I would email Mark II and just ask. I emailed him for questions before and he will respond. Nice guy. Hope this helps.
Will the Mark II Corney Keg washer work with the torpedo style kegs or only the corny style kegs?
John H Truebger on Jan 30, 2019
BEST ANSWER: I have AEB and Kegland cornies and one Torpedo (that I don't like so won't get more) and the washer works fine with all 3.
Do you know who could provide me with a replacement pump impeller assembly?
dave cobb on Mar 7, 2019
BEST ANSWER: You will probably need to contact the manufacturer directly. Just the pump isn't an available product in the market place (I am a retailer who sells these, and I have never found just the pump). I would contact the manufacturer and see if you can order one from them.

Why have I waited so long?
This makes a real deep clean to be done so easily.
I have looked at this for years and finally pulled the trigger.
I use so much less cleaner and sanitiser (I love it to give a good sanitiser rinse before storing too) than I used to.
My first keg cleaned was one I had been soaking with a cleaner - and would have thought cleaned and would have used.
I turned on the pump and was shocked to see the cleaning liquid got dirty, quickly.
I fully recommend this product.

Makes this an easier chore to do
Gone are the days of "bending over the sink while holding heavy carboys". Gone are the days of balancing the carboy over the faucet jet to rise out the carboy you just struggled to clean with a bottle brush. It does take some planning to have them cleaned and ready for use. Each carboy needs the 15-20 min sanitizing wash with the Mark II. So time is part of the equation. That's the easy part. The machine does it beautifully. However there is NO getting rid of the bottle bush and "old school" cleaning if using carboys after fermentation. The lees settle and they do tend to stick to the side walls and bottom of the carboy. I tried to use the Mark II to clean in that situation. It did only a fair job. Residue still needed to be brushed out, but it was much easier to brush out as I believe the Mark II got most of it. I personally have to be sure the carboy has no residue from the lees before the sanitizing process. That said , it is still much easier to accomplish cleaning and sanitizing multiple carboys. I would recommend it.

Just get one and have a better life
If you don’t have one of these, you are working to hard and your stuff probably isn’t that clean.
I should absolutely take 1 star away because there’s no power switch on the cord. Seriously just charge $2 more for the thing.
I love the design: one side is shaped like the end of the tub so you can slide it right under the faucet to fill up.
So fresh. So clean.
Rounded end fits the tub. Soak parts in the reservoir while you run it.
Sprayball purchased separately. Don’t bother. Works perfectly without it.

Every Brewer Needs This
I always asked "Why do you need a Mark II when OxiClean soak cleans my plastic conical overnight?" Plus - looks like cheap plastic design. Due to all the great reviews when this went on sale I picked one up. Actually this thing is pretty well built and I like the fact that it comes with the tub. It is a very optimized design and stores in a small space when done. I also purchased a CIP and it screws on top of the standpipe easily. I will be cleaning my equipment more often and thoroughly with the help of the Mark II. Can't soak my stainless in Oxi so this is the perfect accessory ro clean everything. I'm even going to use it to clean my draft lines. Others say this saves on cleaning agent.

Best Carboy Washer Ever.
This is by far the best carboy washer out there. Now to be fair i felt the nozzle on the end wasn't doing that great of a job so a put a CIP ball on it. I recommend this to anyone who knows the struggle of washing carboys.

Would be nice if all the keg connections came with it. Works great once you create the tubing piece to clean the lines.
