Mark’s Mark II Keg Washer™ is designed to clean and sanitize large vessels like cornelius kegs and carboys. It is also intended to provide a sanitation container for miscellaneous items such as airlocks, thermometers, tubing, keg fittings, and more.

Quiet, Fun, & Easy to Use

  • Very quiet when in use and most importantly speeds up the process of cleaning and sanitizing.   
  • Light in weight.  Easy to store. 

Cleans Kegs

  • Cleans and sanitizes a cornelius keg without having to take apart the ball lock fittings, poppets, and dip tubes. You can clean the keg and the dip tube simultaneously using the T adapter.

Cleans Tubing Too

  • Cleans tube separately utilizing the pump with the additional barb fittings included. 

Cleans Parts

  • Reservoir holds 1.25 gallons of water making it easy to fill and empty with sanitizer.    
  • Saves water and sanitizer. 

The unit does not have an on/off switch, you can plug it directly into a wall outlet to operate the pump or plug it into an outlet that is controlled by a switch. Never leave the keg washer unattended when in use.

When in use, fill the keg washer up to about 1 inch under the brim. The pump is not self priming, so always make sure the basin is full of water before plugging in the pump.

Owner's Manual is included. Please read thoroughly before using. Dimensions of the inside of the washer's reservoir are: 6"L x 12"W x 4"D.

If you don't have one-get one.
It may seem extravagant, but once you own one of these babies you'll wonder how you did without it. I'm considering a second unit so that I can wash/sanitize kegs and carboys simultaneously (we do this during group brews with the club and it's awesome!). The line cleaning feature is a major plus as well!

Not worth $100
Worked somewhat well. When I received it, the part that holds the carboy and/or keg was broken at one of the tabs. Not a totally big deal as I was somewhat able to use it still. Then after the ninth or tenth time using it, the pump quit. I have tried it on numerous occasions and it still won't work. Also, I think the pipe is too short for effective keg cleaning as the pump doesn't really put out that much pressure. Also, understand that if your carboy has valves on it, you need to remove those and clean them separately or you will get an infection in your next beer, that's not in the instructions. All in all, a disappointing purchase that didn't last long and was made from very cheap components and easily not worth what they are charging for it...

Not necessary
I've owned it for a couple of years and have only used it on a few occasions. While it has worked ok, it requires longer than you think to attack stubborn stains. Additionally, my pump died after less than 10 uses...not good. I've gone from using PBW to Brewmeister alkaline wash, and use 2 scoops in a gallon of water for my fermenters and swish it around...works great.

Not worth the Money
Pump broke after seven months. Asked for replacement, but got a lot of excuses and assumptions about usage. Don't waste your time or money.

Doesn't last
Less than 2 years and less than 20 batches. Built cheaply. I knew it wouldn't last forever, but I expected it to last longer than this. Pump is failing. Plastic tab that holds the keg stand broke immediately. Good idea, but could have been designed better.

Great idea, needs better execution
The product itself is great-Kegs & carboys end up extremely clean/sanitized with very little effort. I've saved a ton on PBW and starsan using this thing. A lot of the complaints are valid, such as the tabs popping out on keg/carboy stand. I've never had this happen with a keg or carboy in place, just when I was removing one. The biggest issue is the quality of the fittings for cleaning dip tubes-the barbs are extremely flimsy. I've babied them, but they've finally broken off. It has been about 2 years, but as this is a component that never sees load, it should never happen.

Great Tool!
This machine works great on my carboy! While my carboy was cleaned when I last used it, I used this washer to sanitize it for my next beer before putting the wort & yeast in.

I am getting used to Star-San & not clear about how much to put in. A little goes a long way & if you put in too much, the foaming inside the carboy with this machine will build until it impedes with the vertical spray coming out of the pipe. Then the spray will not reach the bottom of the inverted carboy. I guess this is one time when the foaming action of Star-San may be an undesirable.

I will get past that & put in less Star-San because this machine really whips it up!

Great Idea, but...
Great concept, but pump is a junk. After 3rd wash it was done! While it was working it was great. I didn't even bothered to try to get replacement, just threw it in the trash and I will make my own...
