Getting a jet ski requires a significant financial investment. So, you will have to take care of your investment properly to prevent any loss in the long-term. And by “taking care” we mean proper jet ski cleaning.

Maintaining a jet ski is an ongoing responsibility that you will have to meticulously perform to keep your craft in an optimal condition. There are five steps that you need to follow to properly clean your jet ski.

Firstly, let’s have a look at some tools that you will need for cleaning, and then we will move towards the actual process:

Jet Ski Cleaning Tools You Would Need:

  • Garden Hose: You will need a garden hose for jet ski cleaning. You may also use a pressure washer if you want.

  • Cleaner: You will need a cleaner if you are cleaning a really dirty jet ski. We recommend the Simple Green cleaner which is environmental friendly as well.

  • Soap: Soap is a must in the arsenal of your jet ski cleaning tools. Now, you have two choices. You can either use special boat soap, or you can use the regular car soap. To be honest, there isn’t much of a difference; you can use the car soap and save a few bucks instead.

  • Rags: When it comes to applying the soap on the jet ski or drying it, white cloths work better than a foam sponge. They are easy to get into the irregular places where a sponge can’t reach. You need a bunch of white rags that have some fluff to them along with some microfiber rags.

  • Scrub Brushes: You will also need a long handle scrub brush that will help you in cleaning jet ski seats especially.

  • Wax Spray: To give a final shiny finish to your jet ski, you will need a wax spray as well.

Jet Ski Cleaning Steps:

Step #1: Rinse it properly

Start with good and thorough rinsing of your jet ski using a garden hose. The dirtiest part of your jet ski will be the footwells, with a lot of dirt, slime and goo stuck to it. You can use a power washer to scrub it all away.

If you are using a power washer, be careful around the soft spots and decals. If you get too close to them, you could do more harm than good. Once you are done with your first spray of water, you will need to go another round to reach more inner surfaces.

Take the seats off and open all lids and storage places. Be sure to take out the drain plugs and also avoid spraying water on the electrical parts of the craft.

Step #2: Wash with cleaner and soap

This is the most important part of your jet ski cleaning process. Once you have rinsed your craft and it is all wet, you will need to apply the cleaner mixed with 50% of water.

Spray down the jet ski with the mixture of cleaner and water. You can coat pretty much everything with it including the engine. Make sure to apply extra layers to the footwells.

Note: Only use the cleaner if your jet ski is very dirty and needs enormous amounts of cleaning. Furthermore, avoid the aluminum and oxidized white fiberglass as it can turn yellow.

Now, rinse down the cleaner and get your craft wet again. This time, get a bucket of water (5-gallon bucket is adequate), add a few drops of car soap and get the white rag wet in it.

Divide your jet ski into four areas and make sure to wash all the soap off one area before moving to the other.

Step #3: Clean those seats

You need to take extra care of your seats since that’s where you will be sitting the whole time you are out in the sea.

Just rinse your seat, spray some cleaner again and clean it with a scrub brush. You can also make use of a magic eraser to really clean your seats.

Use it with cleaner; it primarily works great with white seats.

Step #4: Dry and wax it

The hard part of jet ski cleaning is gone. Now, you simply have to deal with plain and simple drying. Take the white rag and wipe down your whole craft. Just push the water out with the rag and when it gets full, ring it and then get back to wiping again.

Pay close attention to footwells and once you have gone through the whole craft, take a new rag and start wiping again. This will take out the little amount of water that is left inside.

Once you are done with the second rag, take some microfiber rags and clean the shiny pieces like mirrors and chrome with it. Check your jet ski one final time to make sure it is completely dry, and you are ready for the last step.

After your craft is completely dry, take some spray wax and spray it over your craft. This will give it a perfect shine and protect it from harmful environmental elements.

Make sure to spray the wax at some cool place where there is no direct sunlight. Use a spray or a combination of sprays to make sure your craft gets protection and shine even at its plastic parts.


This is all there is to jet ski cleaning. The whole process will not take more than 30 minutes, and when it is cleaned, you will be glad you did it. Clean your jet ski after every use and it will remain as good as new.
