Monster Parts Wash Concentrate - 5 Gallon by Monster Labs
DO NOT BUY
This stuff is worthless. Not only does it not remove grease but wont even take oil off parts. Will never buy anything from this brand again.

Works better than expected
After much research I chose the Monster line for a green friendly parts wash. I will keep buying this product for our shop and I was even impressed with their customer service. I called to talk to the company to inquire about the product and they were very friendly and even called to see how I liked the product a week later. Their customer service made a good point this product is a green alternative to a solvent product so you can't expect same results.

Not quite what it claims.
I took a chance and bought this product even though there were many differing opinions about its abilities. I thought I'd give it a chance. Now, 6 months later I've gotten rid of it.
It claims it "is an aqueous substitute for solvent-based cleaners." Sure, it'll wash stuff but it will not break down the thick, caked on grease that most old engines have on them. I spent more time scraping than washing. It also states that it has a "Ph 7 solution with rust inhibitors, to inhibit corrosion of metal parts or steel parts." Not surprising with a water based cleaner, steel parts will rust after being washed with this product.
It did go anaerobic as stated in other reviews but it never did smell, either. I tried multiple different ways to keep the product aerated but, unfortunately, it foams like dishwashing soap so I had to trade keeping it aerated and my washer overflowing with foam vs. it going bad. Looks like I made the wrong choice. I did run the pump often and in colder months it wasn't a problem although it did freeze. Once it got hot, however, it didn't take but a couple of weeks and it was shot.
Bottom line, I don't think this product is all that it claims, costs quite a bit for something with that much hassle and that little benefit.
I'd recommend researching some other product and leave this one be.

Dont buy this product
We purchased this product and do not use it very often, last time i went to use the product is forming a green wax type of solid in the parts washer. We tried to go green but when it comes to getting the job done this product did not work.

5 gallon parts cleaner
works pretty good in my heated 30gal parts washer. i used 6 gallons of parts cleaner to about 20 gals of water but i think ill buy another 5gal of the cleaner and add that too. it has a little harder time cleaning the caked on deep grease but over all i like it.

not so good
we used this product to wash our drill rig parts on a jobsite, not so efficient against grease. i would not recommend for tough job, might be good for small repair shop.

While this product does all it claims to do, it is hard to get the average Joe Mechanic to switch from brake cleaner or diesel fluid as these products dissolve grease more readily. I would recommend this product as advertised.

The truth about Monster
I worked in an automotive machine shop for 4 years and I restore cars now for a hobby. I needed a cleaning solution for my parts washer. I decided to try this stuff since it is near impossible to get the old solvent that I had come to know and love. I bought 5 gallons of the Monster cleaner. I put it in a new parts washer and hoped for the best. I was very disappointed with the cleaning power of this product. I could not even take the grease off my hands. Since then I purchased and replaced the Monster with Simple Green and it works pretty darn good. Both Monster and Simple Green leave a little residue on all your parts. I take that off with carb cleaner before assembly. If you aren't convinced, buy it. Don't even think about adding water to it.... I love northern tool, I don't like this product.

Monster Parts Wash Concentrate
After diluting to the recommended level the solution is too week to be of use, perhaps it is better not diluted.
It leaves a film on the parts and cannot remove grease.

Unhappy then happy
I bought 25 gallons of concentrate for my parts that were greasy much like the other reviews. My parts were not coming clean, I called the company that makes the product and talked to the head monster who was kind enough to guide me through my issue. The company instructed me to add water past the point of where my pump was picking up and since the product is a quick release it was picking up the oil in which was floating at the top. Once I added the water my whole issue was resolved. It worked wonders. I appreciate the customer support I received from this company.
