Mark’s Mark II Keg Washer™ is designed to clean and sanitize large vessels like cornelius kegs and carboys. This keg cleaner 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.

Simple design, made easy work of mundane tasks.
Simple build, includes a Tee fitting for the liquid line to also clean the dip tube in corny kegs. Let's you get other things done while this runs in the background. A second one to run PBW while this one runs StarSan would be even more efficient use of time. It would be a little more convenient to have an on-off switch instead of constantly unplugging it but for what it does, it works perfectly.

This unit is absolutely awesome. It does a great and very thorough job of cleaning and sanitizing both kegs and carboys, and with very little water mess. I would definitely recommend it.

Worth every penny
I can’t imagine washing a keg any other way.

Love how it takes the pain out of keg cleaning
Love this keg cleaner, and easy to use. Recommend you get the option Ball Lock Keg Rinser although I had to swamp the Ball Lock out for Pin Lock. Combined it does a great job. I put PBW and hot water in the bowl, pre-rinse the keg, attached the valve locks, and plug it in for 30 minutes.

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!

Is It Really Worth It
While it does do the job advertised, its not the fastest, but that does give you time to do other things in the interim. But I would not recommend using this for cleaning fermenting buckets unless the bucket was first quick cleaned in the sink since there is only a one gallon reserve of fluid and the holding tank would get overwhelmed quickly with the sludge from a fermenting bucket. This is a gimmicky item which I would not consider rebuying once it is done. But the pump does have a good second use, i.e., pumping cold water from my cooler through my wort chiller since the flow rate is perfect for a fast chill of hot wort.

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...
