Why Clean the Undercarriage?

Best Undercarriage Cleaners for Pressure WashersMany people wash just their cars just so that they look good enough. You wash your car, you want to show it off. However, most of the time, this is simply not enough. You need to wash underneath it as well.

Typically, when you go into the car wash, you don’t always get an undercarriage wash as well – not unless you specifically ask for it. This doesn’t make what’s underneath any less important; quite the opposite, it means you should pay all the more attention to it.

Your undercarriage is closest to the ground than any other part of your car, which means that it’s going to gather quite a lot of debris. Salt, dust, mud, dirt – all of these are to be expected. They will stick to your undercarriage – and the more you leave them there, the more they will layer up.

If you do not clean that grime and particles that have gathered, they may lead to roast and corrosion in the long run. The dangerous part of this is that you won’t even see it – which is why that kind of damage also has that nickname “silent killer.”

Why Is an Undercarriage Cleaner Useful?

If you have a ramp or some way to elevate your car, then you might get away with using the standard attachment. In that case, you won’t have any problems reaching the spots underneath. However, if you are one of those regular car owners that do not have a ramp or a car shop in their home, you’ll probably have to wash the car while it’s sitting on your driveway.

With a regular cleaner, not only will it be impossible for you to clean through the spots, but you’ll also have to keep some awkward angles in order to somehow reach a few of those areas.

However, undercarriage cleaners can make life a bit easier for you. They will either have a curved angle that will allow you to point the nozzle properly or will be set on caster wheels so that you can push them underneath your car. This way, you can clean the underneath of your vehicle, without having to do all that stretching and setting yourself in awkward angles.

Things to Look for In an Undercarriage Pressure Washer Cleaner

Things to Look for In an Undercarriage Pressure Washer CleanerWhen looking for an undercarriage cleaner for a pressure washer, you might want to consider a few aspects. Here are some factors to keep in mind:

1. Pressure Range

Depending on the level of grime underneath your car and the cleaning power that you might need, you might require about 2500 PSI from your unit. So, make sure that the attachment you get can handle this power. In the best-case scenario, you should get a cleaner with adjustable pressure.

2. Type

Undercarriage cleaners for pressure washers come in a variety of shapes and forms. It can be a simple pointed tip, bent at an angle so that you can direct the tip at the bottom, or it might be a wider, wheeled attachment that resembles a sprinkle, which you may roll beneath the car.

The latter option gives you wider coverage, but the former gives you more control. You can buy them separately, but you may want to look for a set that offers you both options. For example, if you tend to clean your car a lot while you are on the road, you might want to go for a wand-type cleaner, as it takes less space.

3. Ease of Installation

You don’t want to spend half the time just struggling to hook the cleaner onto the pressure washer, so go for something that needs one or two easy connection moves. The more additional accessories it has for the installation, the better it will be.

4. Number of Attachments

Depending on the set that you purchase, it may have two to three wands that you may further attach to the caster cleaner. The longer it is, the wider your reach should be. If you have to regularly clean a bigger car – for example, a truck – you might want to look for a set with at least 4 attachments.

Some sets come with some nice extras, such as cleaning mitts or replacements for certain pieces. The more you can get for the price, the more it will benefit you in the long run. Plus, you should look to complete your cleaning set as much as possible.

5. Caster Nozzles

When you go for a caster type of attachment, you might want to pay attention to the number of nozzles that the caster has. Most of the casters have around 4 nozzles, which can do a good cleaning job. But you may expect to see fewer or more nozzles as well. It mostly depends on the models that you choose.

6. Material

You don’t want your undercarriage cleaner for pressure washers to break from the moment you set it up the first time, which is why you might want to make sure you get the right material. Most are made from aluminum or stainless steel, but regardless of your choice, make sure that you don’t sacrifice quality over the budget. You will end up buying these attachments over and over.

Is It Safe to Clean the Undercarriage?

Is It Safe to Clean the UndercarriageCleaning the undercarriage is not only safe, but it is essential as well – that is, if you wish to keep rust and corrosion away. You might want to regularly clean the underneath of your car at the appropriate pressure, and make sure that you are as thorough as you are gentle.

That being said, when you do pressure-wash your car, you need to be very careful about how you do that washing. Make the wrong move, and you might just damage your car. Don’t get panicked, because you won’t ruin your vehicle completely. Still, there are a few things that might be damaged if you pressure-wash your car the wrong way. These are:

1. Damaged Car Underbody Coating

Just like the overall surface of your car, its underbody will also have a coating. This coating will have a variety of purposes, from insulating against the noise to protecting your car against corrosion and rust. If the pressure that you apply directly on the underbody is too high, it might chip off the coating – which can then lead to a couple of other problems.

2. Damaged Car Electronics

You might think that there aren’t any electronics that you can damage underneath your car, but here’s where you are wrong. Your car has quite a few electric connections within the underbody, such as the ABS, brakes, and ESP. If you aim a high-pressure nozzle straight at those areas, you might end up just damaging something – which is why you need to be very careful.

3. Damaged Joint Protective Rubbers

In most circumstances, the joint protective rubbers will not get damaged – at least not if you’ve bought them not very long ago. With that in mind, if they are older, the gums will have gotten pretty weak at that point – and if you use high pressure on them, you may just end up breaking them. This can cause damage to your suspension, which will affect your handling and your driving.

FAQ about Undercarriage Cleaners for Pressure Washers

1. What’s the appropriate PSI for cleaning the undercarriage?

Your undercarriage is sensitive to damage if you use the wrong pressure on it, which is why you may want to keep it at a lower point. 2500 PSI is often the recommended choice, but depending on how old your car is, you might want to go lower than that.

2. How often should I wash the undercarriage?

Unless it is necessary, you should not wash the undercarriage of your car as often as you wash the rest of it. You may feel the need to wash and polish the rest of it after it rained or to make it look nice and shiny. With that in mind, it’s still a good idea to wash the undercarriage once every season, particularly if the roads are salted in winter or you often drive through mud.

3. Do I need to degrease the undercarriage?

Oils and other pollutants can make their way into the undercarriage, which is why you may want to occasionally degrease the area as well. First, you should blast off the main accumulated debris by using the pressure washer and then coat the carriage with soap or degreaser. After it sat for a couple of minutes, you should wash it off by using the pressure washer with a brush attachment.

Wrap Up

If you are looking for the best undercarriage cleaner for pressure washers, you have a few options to go for. Some of them are wands, others are caster cleaners; it all depends on how you prefer to do the cleaning. You should consider all the descriptive features of a product, as the perfect choice for others may not be such a great option for you.

The alternative that we recommend the most is the Ridge cleaner due to its wide coverage as well as its affordability. With that in mind, the M MINGLE is a good runner-up for a similar model, and the Hyde is perfect if you are looking for something smaller and compact. Make the choice based on your needs.
