    Degreaser choice in parts washer

    What does the r3v have to say about engine degreaser products for a 20 gallon parts washer?

    I've long ago stopped using petroleum-based solvents, mostly for health and cracked up hands reasons. You get enuf carb cleaner and brake cleaner on your hands over the years and you just get tired of that nasty stuff.

    I've used "Oil Eater" recently - cheap from local parts stores. It cuts grease pretty fast and is not near as nasty as solvent, although it does have some smell in an open container. I use it straight, not diluted 1:1 as they recommend. I cleaned an E30 oil pan yesterday with Purple Power - worked good, but I read specifically NOT to use it in a parts washer.

    I've read all the forums where they talk about kerosene, diesel, mineral spirits, on & on… None of those things seem like a good choice in a closed garage where I have to breathe it and spill it on my pants.

    Reading about citrus-based cleaners makes them seem like the ticket - smell good, cut grease, water-soluble, non-toxic, etc. Most based on D-Limonene. Way more money usually then an Oil Eater, but you're supposed to dilute it. They are both "basic" vs acidic products.

    But I'm reading that the citrus cleaners are hard on hands, hard on the rubber seals in the pump, and hard on aluminum… This is a big concern as that's a lot of what I clean.

    Also, if these water-based things break down after a short time, that's a big expense to replace all the time. Solvent lasts a while even when gunky. I read that Purple Power breaks down pretty quickly and is bad for aluminum.

    MOAR info…
    I just got a note back from the customer service guy at Kafko International, which makes Oil Eater.

    He says the Oil Eater is the better choice than the citrus for a parts washer, and the stuff is much more effective diluted with water 1:1 than straight, which is interesting, and saves quite a bit of money. The water seems to hold the grease, oil , crud, etc. in suspension away from the part. I always used it straight, thinking it would cut faster.

    From Kafko:

    "If you use Oil Eater too strong, your parts will come out of the bath feeling slippery - add more water. When you have Oil Eater properly diluted with water, the water will keep the oil/grease/etc in suspension away from the part. Another benefit from proper dilution is that when not in use, Oil Eater will release the oil. The oil will rise to the surface. So when you turn your parts washer off for the day you can use a skimmer or simply put an “oil only” absorbent in the reservoir & the oil that has risen to the surface will be removed from the solution helping your solution last longer."



    I found this test report on different degreasers, with cost, effectiveness, and how toxic they are. Interesting to see where brake cleaner lands - I always assumed it was one of the best, just really expensive to use for anything but rotors and such.


    Look where brake cleaner ends up. Simple green is great on oil, not so hot on grease, which is weird. Some work better than others, but are way more expensive. Both Oil Eater and Purple Power sound like you should be careful on aluminum. When I used the PP on the pan, I rinsed it with the hose right away and everything just fell off, so diluting it should help with the corrosion.

      Great info, thanks for posting.

      I found this stuff to work very well but probably expensive in purchased in bulk, I just buy a few aerosol cans at a time. Not really for parts washers but thought I would mention it anyway.



      On a side note, I have used straight Pine-Sol to soak a bank of motorcycle carbs from an inline Honda four. The carbs came out perfectly clean after a few days, no worries about eating up internal rubber seals and aluminum, as well as safe usage in the basement during the winter months.

        Nice - thanks.

        I've always been a sit in the driveway with a scraper and a rag guy, so a parts washer will be nice, even though it's taking up some garage space.

        My son is taking upper level chemistry right now, and he's telling me, "Oh, don't use that, don't get this on your hands, don't breathe that, DO NOT mix these together!" I've learned a lot.

          B2B Solutions Heavy Duty Degreaser amazing product. I wish I had picture of how it left an old oil cooked euro e36 m3 oil filter housing. Just one drop pierced straight through I didn't even dip it. It made the aluminium housing look like brand new without any scrubbing!! I remember going around like a kid again telling co workers while they had looks of no interest of cleaning anything lol.. Its safe to touch but will leave hands extremely dry.

            I have used Oil Eater 1:1 for the last few years, and it's pretty darned good for how well
            it works and how little it tries to kill you.

            The secret is to keep it relatively clean- when it gets saturated, it really slows down.

            But for a good, low- toxic general degreaser, it's pretty good.

              Here's what the Kafko rep said when I asked about how long it lasts..

              The answer to that is different for everyone. We actually add heat to our Flex Line Units to promote evaporation to minimize the volume of liquid waste needed to be disposed of. Our units are user maintained. Proper maintenance (skimming solution & changing the filter when needed) coupled with the heat will allow the user to just add to the solution when low. I have been doing this with my unit for over 15 years. I change it out completely once a year or so. When it gets low I just add to it.

              I need to look into this "skimmer" or absorbent.

                I used paint thinner, worked good on parts off the car.
                Also bought a big bottle of zep industrial degreaser works pretty good but I wouldn't recommend leaving it on any metal surface or aluminum for long periods. Also I'd wear gloves because it'll dry your skin.

                  Not surprised that paint thinner worked well since it is just a combination of some of the harshest solvents going.

                  I wouldn't mind running the harsher chemicals, but I'd wear a pair of canners plus either a respirator, or some good ventilation.

                      Just an FYI -
                      Be careful soaking anything aluminum in Oil Eater or Purple Power. It can react with the aluminum and leave black blotchy discolored areas. There's no deposit or rough surface, just a black stain in the aluminum.

                      Cleaning and scrubbing with it is fine, then rinse with water. It's the overnight soaking that does the staining.

                        Ah, yes, I had that happen once-
                        oddly, Oil Eater sprayed on, scrubbed, and rinsed off
                        leaves a very bright finish on aluminum.

                          I've always used odorless mineral spirits (paint thinner). Cuts dirt and grease very well, has little to no smell and is petroleum based, so if anything, it moisturizes my hands.

                          I do use Super Clean a lot though, but not in a solvent tank. I like to mix it 1:1 and use it for everything from cleaning the bathroom to scrubbing grime off engine parts.
