How To Clean A Jet Ski Seat – Getting Rid Of The Black Dots

Below are the steps I take to clean dirty jet ski seats.

  1. Remove the seats.
  2. Thoroughly wet the seats.
  3. Spray the mold & mildew remover cleaner (Amazon Link Ad) on the seats.
  4. Let it sit for a minute.
  5. Wet the Boat Erasers (Amazon Link Ad) and wipe all the affected areas.
  6. Thoroughly rinse the seats.

When the seats are cleaned and dry, put on vinyl protectant (Amazon Link Ad) to keep the seats protected.

What if the seats are still not cleaned? Keep reading on!

Cleaning Really Dirty Seats

Sometimes I have a few seats and soft items like covers that don’t get cleaned with the mold and mildew sprays made for such things.

Sometimes, you just need something a little stronger!

Warning: Do a hidden test spot before doing the whole area!

Repeating the steps in the last section, but instead of the mildew cleaner, use this Outdoor Cleaner (Amazon Link Ad). This stuff will stain clothes, so make sure to not wear your good clothing. Also, I suggest you try to avoid the seams and stitches of the seat.

Boat Erasers

The real magic has been boat erasers (Amazon Link Ad), which are magic erasers made for boats.

These boat erasers are not my daily cleaning of my Sea-Doo, but my go-to for really dirty seats. Most of the time, a simple boat wash and Simple Green (Amazon Link Ad) gets them cleaned. I figured, if you Google this, then you have filthy seats and need a good solution.

I would not use regular magic erasers, these boat erasers are made for boats, and it’s soft materials like seats. You’re going to have to trust me on this one, they’re way better for your boat than magic erasers.

Just Paint It

I’ve cleaned a lot of boat and watercraft seats, and sometimes the black dots/marks and stains won’t come out.

The vinyl freckles, just your skin, and it’s there forever. It looks like mold and mildew, but it won’t come out because it’s damaged. People don’t believe me when I say this, they keep trying to remove the black dots, but they won’t come out on some seats.

The last thing you can do is simply paint the seats with a vinyl spray paint. This is super easy to do if the seat is one color, but if not, you have to mask off the areas you don’t want to paint.

The video below shows how to do it and how effective it is.

How To Clean The Whole craft?

Cleaning the whole watercraft is a different process that I cover here.

You don’t want to clean your whole jet ski the same way you clean the seats. The seats on a jet ski are very different and need different care when it comes to cleaning.

Cleaning The Cover

Cleaning your jet ski cover is similar to cleaning your jet ski seats, both are soft surfaces and hold on to mold/mildew.

To clean the cover, you put it on a flat surface and spray it down with water and then the mildew remover cleaner. Make sure the cover is over something that doesn’t get affected by bleach.

Can you wash the cover in the washing machine? You can put your cover in the washing machine and clean on a gentle cycle, but I don’t suggest putting it in the dryer.
