Best Dirt Bike Cleaner (Kit, Brush, Degreaser, Spray, More Products)

Have you heard the horror stories out there about using the wrong cleaning products for a dirt bike? If not, I’ve got a few I could tell you! If you aren’t using the right products, you risk doing damage to your bike. With that in mind, the following dirt bike cleaner and kit, as well as a few miscellaneous cleaning products, will make washing your dirt bike quick and safe.

As I mentioned, if you use the wrong products to clean your dirt bike, you stand the chance of running it. When I was a kid my dad owned an autobody shop and I had an awesome supply of different automobile cleaning products. Because of this, I was able to experiment with quite a few different formulas.

Most car cleaning products worked on my dirt bike, but some cleaners ate away at the finish on many of my dirt bike parts. Overall, I definitely recommend AGAINST using just any cleaning solution on your bike.

Here are some of the best options for picking a dirt bike cleaner, kit, brush, etc., that is actually SAFE to use… and they work.

Dirt Bike Cleaning Kit

Although there are a handful of different dirt bike cleaning kits out there, you will end up getting better tools if you buy each piece individually.

Most dirt bike cleaning kits don’t come with quality brushes and cleaners. Instead, you generally find a good cleaner with some “okay” cleaning brushes, etc. On the other hand, if you do find a good kit with brushes, it probably won’t include all of the cleaners and degreasers that you need.

With that in mind, the following products are great for cleaning a dirt bike. Just purchase the cleaners and products you need so that you can put together your own cleaning kit.

Dirt Bike Cleaning Products

Muc Off is a great engine degreaser and more. In fact, if you’re wondering what the best product to clean a dirt bike is, it’s probably this stuff.

The best products to use on your dirtbike are ones that are specifically made for dirt bikes and motorcycles. These tailor-made products don’t contain any of the solvents that eat away at the various parts of your bike.

For example, if you use the wrong cleaner on your engine case, you will see that the finish begins to erode. Not only does this look terrible, but it makes the bike more susceptible to rust and other contaminants.

Engine Cleaner / Degreaser

What can you use to clean a dirt bike engine? You can use most cleaning supplies on your dirt bike, but not all. But because of the risks of using the wrong stuff, I recommend sticking with the basics:

• A dirt bike cleaning kit
• Specific motor-safe, and plastic-safe, cleaners
• Dish soap

Surprisingly, good ole dish soap works great. Since most dish soap has a degreasing element, it actually works great for removing dirt and grime from your engine and plastics. (Don’t use dish soap on your car or truck.)

Plastic Cleaner

Depending on how bad your plastics are, you may be able to get away with using a fine steel wool pad and some water. Most of the time I just use some good dirt bike soap (click here to view pricing and read reviews on Amazon) and fine steel wool will clean my plastics and graphics.

NOTE: Steel wool doesn’t take away ALL blemishes (especially the deep scratches), and you definitely do NOT want to over-scrub because it will make your plastics a bit dull. All-in-all though, steel wool and soap is my go-to product to clean dirt bike plastics.

If steel wool and dirtbike soap won’t do it, you can try something like McGuire’s plastic cleaner (view pricing and read reviews) on Amazon.

However, if your plastics are really bad, I recommend using a full-on plastic “renew” kit like PC Racing Plastic Renew – view pricing and read reviews on Amazon.

Chain Cleaner

Not only is keeping your dirt bike chain tension properly adjusted important, but keeping your chain clean and lubed is also necessary. However, you shouldn’t use just any cleaner or lube on your chain, especially if it’s an O-ring.

As with most cleaning products, it is best to buy a specific dirt bike chain cleaner rather than using anything you’ve got laying around. Maxima makes a good cleaner, lubricant, and chain guard kit specifically made for dirt bikes. Click here to view pricing and read reviews on Amazon.

In addition to the right chain cleaner, something like the Grunge Brush also makes cleaning a dirt bike chain easier and safer. Click here to view pricing and read reviews on Amazon. Just make sure that you don’t use a wire brush or something too rough on your chain.

Carb Cleaner

If you’ve got lawnmowers, hot rods, older dirt bikes, or anything else with a carburetor, chances are you’ve got some Gum Out lying around. Gum Out carb cleaner is basically an in-stock item for most garages. It’s kind of like WD40. We’ve all got some laying around somewhere, or at least, we have at one point in time.

Need more? Here’s a link to buy more Gum Out on Amazon.

Aluminum Frame

You can use a special aluminum cleaner, but WD40 and a chunk of steel wool work great. In fact, I usually just use water and steel wool without the WD40.

NOTE: I currently have a Works Connection skid plate on my dirt bike. The frame protection that the skid plate offers makes cleaning every surface of the frame challenging. I do like having the skid plate on the bike, but it does make me need a cleaner (usually WD40) to get the bike as clean as I like.

Cleaning Brush

If you don’t have a soft-to-medium brush around, here's a good one on Amazon. It’s technically a bicycle cleaning brush, but you can use it on a dirt bike as well.

It’s good to have a fairly soft brush so that you don’t scratch your plastics, etc. I wouldn’t say that these are necessary, but they do work nicely. Using a brush instead of just a wash mitt is for heavily solid areas like your tires and chain, as well as for areas around your engine where there are multiple surfaces and angles, etc.

Again, you don’t have to use a dirt bike cleaning brush but if can, they are a great little cleaning accessory.

Fuel Injection Cleaner

Have you experienced a loss of acceleration, less power, or rough idling? If so, it could be that you need to clean out your fuel injectors.

Seafoam makes a solid fuel injector for dirt bikes and many other applications. It cleans fuel injectors, intake valves, and ports to get your bike running clean and smooth.

After Wash Spray for Dirt Bikes

Okay, so what do you spray on a dirt bike after washing it?

Muc-Off Motorcycle Protectant is probably the “best” spray-on product to use on your dirt bike after you wash it. If you’re interested, you can view pricing and read reviews on Amazon.

However, if you don’t want to buy a specific dirt bike cleaning product like Muc Off Protectant, you can use WD40.

This may sound weird, but I almost always spray WD40 on my dirt bike’s engine, exhaust, swingarm, and any other metal parts, after I wash it. Spraying WD40 is a great way to keep the various parts on your dirtbike clean, shiny, and safe from moisture.

NOTE: WD40 is not a dirt bike cleaner and if you spray it on your engine it will “smoke” and burn off when you start it up for the first time. Don’t worry, this is normal, safe, and expected. It’s just burning off the protecting layer, and you can re-spray it after you’ve ridden and cleaned the bike.
