Jetski Cleaning Process

Why Proper Jetski Cleaning Matters

Jetskis face unique challenges in Southwest Florida's marine environment. Unlike larger boats, PWCs have more exposed surfaces and intricate water systems that trap salt. Without proper cleaning, salt crystallization leads to:

  • Corrosion of metal components and fittings
  • Gelcoat oxidation and fading
  • Clogged cooling systems reducing performance
  • Premature wear of seals and gaskets

Essential Products & Tools

Recommended Products from Marine Detail Supply

Cleaning Products:

  • • Starke Salt Clean (rinse additive)
  • • Starke Pure Clean Boat Soap
  • • Starke Ultra Clean SiO2 Soap (for coated surfaces)

Tools & Accessories:

  • • Microfiber wash mitts
  • • Foam cannon or spray bottle
  • • Marine-safe brushes
  • • Chamois or waffle-weave towels

Step-by-Step Cleaning Process

Step 1: Immediate Post-Ride Rinse

Time Required: 5 minutes
Frequency: After every saltwater use

  1. Start the jetski and flush the cooling system with fresh water using a garden hose adapter
  2. Run the engine for 30-60 seconds to clear salt from internal passages
  3. Spray the entire exterior with Starke Salt Clean mixed with fresh water
  4. Pay special attention to the pump area, steering components, and any metal fittings
  5. Allow to air dry or towel dry the seat area

Pro Tip: Never skip this step! Salt damage occurs within hours of exposure, especially in Florida's heat and humidity.

Step 2: Weekly Deep Clean

Time Required: 30-45 minutes
Frequency: Weekly with regular use

  1. Pre-rinse: Thoroughly rinse with fresh water, using Starke Salt Clean for enhanced salt removal
  2. Soap application: Mix Starke Pure Clean (1-2 oz per gallon) in a bucket or foam cannon
  3. Washing: Work from top to bottom using a microfiber mitt. Clean the hull last to avoid transferring bottom grime
  4. Detail areas: Use a soft brush for textured surfaces, intake grates, and around decals
  5. Rinse thoroughly: Remove all soap residue, paying attention to crevices where soap can collect
  6. Dry completely: Use a chamois or microfiber towels to prevent water spots

Step 3: Monthly Protection Application

Time Required: 60-90 minutes
Frequency: Monthly or quarterly depending on use

  1. Complete the weekly deep clean process
  2. Apply marine wax or ceramic coating to all gelcoat surfaces
  3. Treat vinyl seats with marine-specific protectant
  4. Apply corrosion inhibitor to metal components
  5. Check and clean the ride plate and pump for debris

Common Mistakes to Avoid

Using automotive products

Car washes and waxes aren't formulated for marine environments and can leave residues that attract salt.

Pressure washing the engine bay

High pressure can force water into electrical connections. Use gentle rinse pressure only.

Skipping the cooling system flush

Internal salt buildup is the #1 cause of PWC cooling system failures in Florida.

Seasonal Considerations

Hurricane Season (June - November)

  • Increase cleaning frequency due to higher humidity and rain
  • Apply extra protection before storm season
  • Clean immediately after any storm exposure

Dry Season (December - May)

  • Focus on UV protection with quality marine wax
  • Clean more frequently during peak usage months
  • Pay attention to increased salt concentration during dry periods

Pro Results Checklist

  • ✓ No visible salt residue or water spots
  • ✓ Gelcoat has uniform gloss without oxidation
  • ✓ All metal fittings are corrosion-free
  • ✓ Engine flushes clear water (no debris or discoloration)
  • ✓ Vinyl surfaces are clean and protected

Jetski Cleaning FAQs

Common questions about jetski maintenance and cleaning in saltwater conditions.

How often should I clean my jetski?
Rinse with fresh water after every saltwater use. Deep clean weekly if used frequently, monthly for occasional use.

No, use marine-specific pH-neutral soaps like Starke Pure Clean that won't damage gelcoat or leave salt-attracting residues.
What's the most important step in jetski maintenance?
