Degreasers for parts washers are essential to the long and healthy life of any industrial business. From hardware manufacturing all the way up to diesel engine refurbishing, parts washers are used every day to keep your machinery (and your products) clean, crisp, and strong.

Larger parts washers can handle wire shelving, rail bearings, turbine boxes, and even automotive parts. If you need something cleaned to the point where it looks brand new and right off the shelf, you need a degreaser that’ll work with the parts washer you have and the job you need to do.

But you don’t want to use any old degreaser in a parts washer; otherwise, it wouldn’t be much better than an old soak tank! Finding the best degreaser for your parts washer requires a little homework, but once you find a degreaser you like, you can use it every single time you need to clean your hardware. Once you’ve identified the toughness of the job, you can start looking at the right degreasers for your needs.

Here are our recommendations for the 4 best degreasers for parts washers on the market:

B’laster 5-PWS Parts Washer Degreaser / Solvent

B’laster parts washer solvent is a high-powered solution to the challenges of cleaning and maintaining mechanical parts. This solvent is acts as a degreaser (and then some) to completely eliminate grime, gunk, and buildup that’s associated with using a parts washer. In fact, this degreaser will even dissolve mineral deposits left behind from machine parts that other degreasers just can’t handle.

The residue-free formula makes it perfect for any metal application, and it’s even usable with plastic parts in a pinch. In fact, it won’t even eat away paint, meaning this is the ideal parts washer degreaser to use in a facility that color-codes different areas (like a warehouse).

Still, this solvent-degreaser product needs to be handled with care. Its formula is still harmful to bare skin, and it requires immediate medical attention if it happens to splash in someone’s eyes. On the other hand, it’s specifically formulated to have a higher flash point than other chemicals, so you don’t have to worry about it bursting into flame on hot days.

This powerful formula is a strong fit for just about any industrial application. The only catch is that you’ll need some room in your budget to allow for repeat purchases. Even though it’s sold in 1- to even 5-gallon buckets, B’laster solvent could be pricey!

Clean Parts Easy with B'laster Parts Washer Solvent

Simple Green Cleaner Degreaser

The Simple Green 19128 Crystal industrial cleaner/degreaser is another heavy-duty answer to cleaning mechanical parts. It’s intentionally formulated to be fragrance-free for use in industrial and commercial settings, and it rinses away after application.

That kind of heavy-duty cleaning power is great for places where workers are in closed quarters or prone to allergic reactions via chemicals. So if you have any employees who normally can’t handle fragrant solvents, they can still work with your parts washers by using this degreaser. Plus, the degreaser is 100% non-toxic and biodegradable, which means you won’t have to fill out a bunch of paperwork or fork over thousands in fines in the event of a spill. The Simple Green formula isn’t even corrosive, so you know for a fact that you won’t wear down the parts that keep your machinery running.

The 1 gallon bottle size is perfect for short-term use and quick portioning. If you need something you can buy at a decent price point while eliminating chemical hazards, this is your solution—without a doubt, one of the best degreasers for parts washers period.

Oil Eater Original 1 Gallon Degreaser

Oil Eater Original 1 gallon cleaner/degreaser is, as the name says, the original formula used by Oil Eater to clean industrial products. This fast-acting degreaser is hard on buildup and residue, but it’s made with ingredients that are eco-friendly. In fact, the whole formula is based on water, and it doesn’t contain a single acid.

Still, Oil Eater Original degreaser comes as a concentrate. You need to dilute it with water if you’re not going to use it for a high-demand project. Normally, you won’t have to worry about that for a parts washer. But this is important because Oil Eater can be used around a facility as a general cleaning agent when it’s diluted, meaning it solves two problems in one product.

Meguiar’s D10801 Super Degreaser

Meguiar’s D10801 Super Degreaser is a reliable choice for degreasing jobs both inside a parts washer and around your facilities. The formula is crafted to break down even the toughest grease spots in a matter of minutes. For routine parts cleanings, the grease practically melts away!

The product leaves behind a pleasant herbal fragrance after it’s applied, but it’s specifically made to never leave a residue. It’s not going to be as powerful or specific as B’laster, but Meguiar still creates a fine degreaser formula that’ll work in your parts washer. Hands down, it’s one of the best degreasers for parts washers around.

How Do You Pick the Right Degreasers for Your Parts Washer?

So which degreaser is right for your parts washer? That comes down to one big question — what kind of job do you need to do?

If you need a heavy-duty solution that’s only ever going to be used in your parts washer, go with B’laster (see full specs). That formula is made to be used in a parts washer only, and it’s specifically intended to make your hardware look new and stay strong. If you have a big facility that needs to constantly degrease and maintain mechanical parts, go with B’laster to make sure you get the most out of every piece of metal in your business.

For lighter, less frequent jobs, you can get away with using a Spring Green or Oil Eater. These two brands make concentrate that can go into a parts washer raw, but also be diluted into a powerful everyday cleaning agent. This makes it a great product to have in your facilities for regular maintenance and taking care of spills in addition to cleaning mechanical parts. These all-arounders can also work in less industrialized applications, specifically warehouses that use powered work equipment like bulk lifters or elevator pickers.

Meguiar’s degreaser (see full specs) is a decent middle ground among the other options. It’s affordable enough to use at smaller-scale facilities, and it’ll do excellent work in a parts washer. You can also use it specifically on grease spots around your facilities, which makes it great for automotive manufacturing plants, refineries, and other industrial areas.

So, in the end, what determines the best degreaser for parts washers is your particular washer and its needs. And hopefully, with this article, we’ve answered that question. Good luck!
