Krausen Killer Carboy Washing System


SKU# 41058

Flat Rate Shipping only $7.99 only from Northern Brewer

Introducing the first system to make cleaning your fermentors as much fun as filling them!

Sit and smugly watch, hands-free as your worst-nightmare of crusted-on krausen simply fades away. A solution of water and PBW is pumped through the washer, effortlessly obliterating caked-on crud. Spend less time and water cleaning your equipment. Ideal for plastic carboys where you cannot use a brush to scrub the inside. Keep those plastic fermentors scratch free for years of use.

Once your carboy is sparkling clean, simply switch out the PBW solution with a SaniClean solution, and you have a hands-free, rinse-free sanitized carboy in minutes.

Work great for kegs too. Using a soda keg disconnect and some tubing (not included), you can even clean those hard to reach keg dip tubes without disassembling the keg.

SAVE $10.23 by buying as a bundle!

Please Note: Carboys not included, only shown for demonstration purposes.

We recommend the use of a GFCI outlet or adapter during use. 


Availability: In stock

Product Details

Cleaning and sanitizing a big 5 or 6 gallon carboy can be an intimidating job — what if we told you it could be hands-free, and could be done with just 1 gallon of solution instead of 5 or 6?

The Brewery Essentials Carboy Wash kit makes this a reality — works with both glass and plastic carboys, powered by Mark’s Keg Washer (don’t let the name fool you — it works for carboys, too!) and using the awesome no-rinse action of Saniclean. Using a soda keg disconnect and some tubing (not included), you can even clean those hard to reach keg dip tubes without disassembling the keg.

The janitorial part of brewing just got fun! with the powerful action of PBW, you can smugly watch the crusted-on gunk simply wash away. Includes a carboy brush (for use on glass carboys only), and a carboy dryer to help make sure your fermentors are drained and stored dry between uses.

Please Note: carboy not included.

    Great system
    System provides ease of setup and use along with an ability to ensure cleanliness of carboys. Far exceeds a rinse and scrub method for cleaning and sanitizing.

    why didn't i buy this sooner?!!
    this thing is incredible! i cant believe i waited this long to buy the mark II keg & carboy cleaner! this thing is a beast. i cleaned 3 carboys and one keg last night and i dont think they have ever been cleaner! really easy to use and pretty quiet too. any dirty spots left inside the carboy were easily removed with the brush, then put right back on the cleaner to keep cleaning! i love it. and now i have more time to brew instead of clean!

    Great time saver
    I use it to clean and sanitize my kegs and my big mouth bubbler. Just plop the keg on top, start the pump, let it run 5 minutes and you got a perfectly sanitized keg / bubbler / hoses. I'm giving it 4 stars because I wish the basin was bigger so that I could fit more stuff in it (spoons, airlocks, etc). Right now I can fit some stuff in there, but some of it only partially so I've got to move them around.

    Pump is worthless
    I had high hopes that this system would make brew day clean up easier. The first time I used it worked great. A couple weeks later brewed again and pump doesn't work. I called nb who without hesitation replaced the pump as apparently a bad batch of propellers were out. New pump delivered worked great fast forward to today when I used it again and again pump doesn't work. I'm done using this product and simply bought another aquarium pump. Again customer service was great by nb but it's just a bad product and has caused more headaches for a product intended to make brew day easier

    Response from Northern Brewer
    Hi Mikey,

    Thanks for your review! This product has been around for awhile, and it's one that most of use here, in our own brewing. Normally it's a solid piece and we don't get much negative feedback on it! The replacement may have been defective as well. We could replace it again, or we could compensate you with some store credit instead. Let me know which works best for you!

    Krausen Killer Carboy Washing System - wasn't needed after all
    I just started using four big mouth bubblers for concurrent fermentations, and have found they are exceptionally easy to clean out with a soft sponge after heavy kraüsen primaries. Haven't needed the carboy washer that I thought I would. Sorry about ambivalent review. CT

    This is the absolute best
    This is the absolute best system that I have found to clean and sanitize carboys. All you need to do is fill the tank with water, add the cleaner and let it run.

    Can you clean 6.5 gallon carboys with this system?
    A shopper on Aug 14, 2017
    BEST ANSWER: Absolutely! I clean all carboys: 5 gallon, 6 gallon, and 6.5 gallon, plus my Big Mouth Bubblers, my kegs, tubing, etc. This is one of my most favorite items. I can clean any item with one gallon of water, and I then I can sanitize after changing out the water and adding sanitizing solution. It works so well!
    Can you clean a "Big Mouth Bubbler" with it?
    D A on Oct 15, 2015
    BEST ANSWER: You can use it with the glass Big Mouth Bubblers. However they don't fit on perfectly so you may have to hold them on as you wash them with the washer.
    Can you clean 6.5-gallon fermentation buckets with this system?
    M I on Jul 21, 2016
    BEST ANSWER: You can, but liquid may splash out of the tray on the washer.
    Can I clean big mouth fermenters with this kit?
    Franklin B on Sep 21, 2015
    BEST ANSWER: You can clean big mouth bubblers with the marks keg washer in this system...the mouth just barely fits on the stand and you would want to make sure it is on there well and watch it carefully. The big mouth design makes a cleaner like this not necessary since you can get your whole arm inside

    but yes

    it will work.
    does this kit come with the attachments for cleaning keg tubes ? I notice on the $99.00 one it has all of the adapters tks
    Noel D on Aug 30, 2015
    BEST ANSWER: Yes, it is the same keg washer package, simply bundled with some other useful items.
