Buying a parts washer? These 5 things will surprise you in the very first days!
In theory, it seems simple: you can wipe a dirty part with a rag, spray it with a cleaner, or go over it with a brush, and it will do it somehow. But in a car service, that “somehow” quickly starts to get in the way.
You take apart the suspension, and bolts, mounts, and parts covered in grease land on the bench. A moment later, there is a brake caliper, then another part coated with old oil and road grime. The worktop turns black, your gloves get sticky with dirt, and instead of putting the car back together – you are standing there with a brush in your hand.
Exactly. And this is where a parts washer comes in. Like a hero to the rescue (in our case, red rather than white). Check whether this is the right kind of equipment for you.

1. Parts removed from the vehicle no longer end up all over the garage
You remove a part from the car and the usual question comes up straight away: where do you put it? On the bench, on a cardboard box, on a trolley, or maybe on the floor?
After a few days with a parts washer, you start to appreciate one simple thing: dirty parts have their own place. You are not spreading grease around the workstation or moving parts from one corner to another.
No more putting dirty parts down “just for a moment.”
That “just for a moment” often turns into a mess that stays with you until the end of the day. A parts washer cuts that short – the dirty part goes where it should.
You feel it most when working with:
- bolts and mounts,
- brake caliper brackets,
- suspension components,
- tools covered in grease.
You have one place for dirty parts, one place to clean them, and less mess on the bench. Maybe it does not make much difference when you work on one car a day, but with several – definitely.

2. You spot faster whether the part is fit to go back on
Dirt can be deceptive. A part may look “good enough” until you wash off the old grease, dust, and oil.
After cleaning, it is easier to judge whether the part can go back on the car or whether it is better to replace it straight away.
On a clean part, you will spot these things faster:
- cracks,
- worn areas,
- pitting and corrosion,
- damaged threads,
- old gasket residue,
- signs of overheating or friction.
It is better to spot the problem right away than come back to the same job a few days later.

3. Less scrubbing by hand, but not zero work
A parts washer can take a lot of strain off your hands. But let us be honest – it is not a magic box where you throw in any part and take it out looking like new.
The biggest advantage? Less time spent standing over every part with a brush.
When does a parts washer get the job done quickly?
It works best on typical dirt: fresh oil, grease, road dust, light deposits, and dirt from tools.
In cases like that, it is often enough to wash the part, inspect it, and get it ready for the next step. No long scrubbing on the bench.
When do you need a bit more patience?
With heavier dirt, it is better to be realistic. Old, dried grease or a thick layer of carbon build-up will not always come off straight away.
Let us be honest. Not every parts washer is the same. A simpler model may handle everyday dirt, but with tougher cases, pressure, fluid temperature, and the way the cleaning agent is applied matter much more.
An example? The REDATS D-490 works at 4.8–8.2 bar and heats the fluid up to 50°C with a 2000 W heater. These are exactly the kinds of things that help with more stubborn dirt.

4. It is easier to get your tools sorted before the next car
After a job, tools are often covered in grease, oil, and road dust. You put them aside “for later,” and then the next time you reach into the drawer, you grab a greasy socket.
A parts washer helps you get them back to a usable state quickly – without having to wipe each one down by hand for ages.
You will appreciate it most with:
- wrenches,
- sockets,
- extensions,
- pliers,
- small support tools.
With one repair, the difference is small. With several cars a day, it becomes much more noticeable.
Less dirt on your tools means less dirt in the drawers, on your gloves, and on the next parts you work on.

5. You start using less rags, paper, and cleaner
With manual cleaning, materials disappear faster than you think. A bit of cleaner for one part. Two sheets of paper for the next one. A rag to wipe down the third. And so it goes all day long.
After a few days of working with a parts washer, you start to notice the difference: less wiping paper ends up in the bin, fewer rags turn black with grease, and you reach for cleaner less often with every dirty part.
Instead of spraying and wiping each part separately, some of the dirt goes straight into the washer. This helps reduce the use of:
- paper,
- rags,
- wiping cloths,
- cleaner,
- gloves getting dirty from constant wiping.
It is not about cleaner no longer being needed. It still has its place. But it does not have to be the first answer to every greasy bolt, bracket, or tool.

When is a parts washer worth it, and when is it not?
A parts washer makes sense when it actually gets used. If it is only going to stand in the corner waiting for “someday,” then it may be worth thinking twice before buying one.
| A parts washer will be a good choice if… | It may not be necessary if… |
| you clean parts after disassembly every day or often | you clean parts only occasionally, once every few weeks |
| you work on suspension, brakes, and parts covered in grease and oil | most of your repairs do not require part cleaning |
| bolts, brackets, mounts, and small parts often end up on your bench | you usually replace parts with new ones and do not prepare them for refitting |
| scrubbing by hand is starting to take too much time | wiping down individual parts quickly is enough for you |
| you want a cleaner workstation | dirty parts rarely end up on your bench |

Which REDATS parts washer should you choose? Model comparison
Not every parts washer is meant for the same kind of work. One will be better for small parts and tools, another for larger components, while the D-490 cabinet washer makes sense if you deal more often with heavier dirt, carbon build-up, and larger parts. Below is a quick comparison of REDATS models.
| Model | Washer type | Capacity | Performance | Dimensions | Best for |
| REDATS D-410 | Bench washer | 13 l | flow rate 3.3 l/min | 460 × 340 × 225 cm | small parts, bolts, small tools, occasional cleaning |
| REDATS D-440 | Bench washer | 76 l | flow rate 12 l/min | 781 × 539 × 875 mm | regular cleaning of tools and parts in a typical car service |
| REDATS D-470 | Bench washer | 150 l | flow rate 20 l/min | 1150 × 560 × 900 mm | larger parts, several tools at once, more intensive work |
| REDATS D-490 | Cabinet washer | – | pressure 4.8–8.2 bar | 1715 × 791 × 625 mm | heavier dirt, carbon build-up, larger parts, for example turbochargers |
In short: choose the D-410 for small parts, the D-440 for typical car service work, the D-470 for larger components, and the D-490 when you need a cabinet washer with heating, pressure, and drying.

FAQ – the most common questions before buying a parts washer
- Will a parts washer work well in a small car service?
Yes, if you regularly clean parts, tools, or small items after disassembly. In a small place, it also helps keep the workstation tidier.
- Does a parts washer completely replace manual cleaning?
Not always. With typical dirt, it greatly reduces scrubbing, but with old grease, carbon build-up, or hard residue, you may still need to help it along with a brush.
- What parts are most often cleaned in a parts washer?
Most often: tools, bolts, mounts, suspension components, caliper brackets, calipers, housings, and small parts after disassembly.
- When might buying a parts washer not make sense?
When you clean parts only occasionally, from time to time. A parts washer works best where dirty parts come back every day.
