Keeping your jet ski or waverunner clean isn’t just about looks—it’s essential for preventing oxidation, maintaining performance, and prolonging its lifespan. Jet skis are exposed to harsh elements, like saltwater, UV rays, sand, and lake scum, making regular detailing a must.
Whether you’re learning how to clean a jet ski or want to step up your jet ski detailing game, this guide covers everything you need—from prep and product tips to polishing and protection.
The best times to detail your jet ski are:
- At the start of the season – To remove oxidation and prepare for summer riding.
- Before winter storage – To prevent grime buildup and protect the finish during off-season storage.
A properly detailed jet ski not only shines but also performs more efficiently. Overall, the process of detailing a jet ski is similar to detailing a boat. Watch this DKTV video to learn how to detail a wave runner:
Step-by-Step Guide: How to Clean & Wax a Jet Ski
1. Rinse Thoroughly: Start by rinsing your jet ski with a hose or pressure washer. This removes loose dirt, salt, and debris, making it easier to focus on problem areas.
2. Clean the Engine & Mechanical Components
Use a specialized engine cleaner like Citrus Cleaner to safely remove grime from engine components. Avoid letting the cleaner dry on painted areas—it may cause staining, especially in sunlight.
3.Wash the Exterior
Use a pH-balanced boat or car soap like Black Cherry for general washing.
- Use Ex-Con for heavy grime and buildup (especially under the hull).
- Use a Medium Duty Brush for hull surfaces and a Microfiber Wash Mitt or Soft Bristle Brush for glossy panels.
- Rinse thoroughly with fresh water to prevent chemical residue buildup.
4. Clean & Condition the Seat
Spray Special Force All-Purpose Cleaner onto the seat and agitate with a soft brush to remove mildew and buildup. Apply Leather Conditioner to protect the seat and reduce cracking or sun damage.
5. Dry Completely
Use an ultra-absorbent Gauntlet Microfiber Drying Towel to prevent water spots and streaking.
6. Polish & Protect the Paint
Depending on the paint condition, use a polishing compound to restore gloss or remove oxidation.
- For minor scratches, a polish will do.
- For oxidized or chalky paint, use a compound first.
A machine polisher is recommended for best results, but hand polishing can work for smaller areas.
7. Apply Jet Ski Wax or Protective Coating
Seal the surface to protect against UV rays, oxidation, and water damage. Apply a coat of sealant like our STS3000 or a Ceramic Coating to protect the watercraft’s finish.
8. Regular Maintenance Tips
- Wash and spray wax your jet ski after every few rides to prevent buildup.
- Avoid using abrasive pads or harsh chemicals that could damage the finish.
- Always follow the instructions on detailing products for best results.
Can You Use Car Wax on a Jet Ski?
Absolutely, car wax can be used on jet skis if it offers UV and water protection. However, a jet ski wax or marine-specific sealant is recommended for better resistance to saltwater and long exposure to sun and moisture.
By following these steps and using jet ski-specific detailing products, your waverunner or personal watercraft will stay looking sharp and performing at its best all season long.
