How to Maintain and Store Your SUP Board Properly

Stand-up paddleboards (SUPs) are built to handle sun, water, and adventure—but a little care goes a long way in extending their life. Whether you paddle every weekend or your board only comes out for summer fun, proper maintenance and storage are key to keeping it performing like new.


Below is a complete guide on how to clean, maintain, and store your SUP board the right way.

1. Rinse Your Board After Every Use

Saltwater, sand, dirt, and algae can all damage the finish and hardware of your SUP board over time.
Make it a habit to:

  • Rinse the entire board with fresh water

  • Clean the deck pad to prevent grime buildup

  • Rinse fins, fin boxes, and tie-down points

A quick rinse prevents corrosion and keeps your board looking new.

2. Deep Clean Periodically

Every few weeks—or after long trips—give your SUP a proper cleaning.

How to deep clean your SUP:


  • Use mild soap or a board-safe cleaner

  • Gently scrub with a soft cloth or sponge

  • Rinse thoroughly and dry completely

Avoid harsh chemicals or abrasive scrubbers, especially on inflatable SUPs.

3. Check for Damage Regularly

A quick inspection can prevent small issues from becoming bigger problems.

Look for:

  • Dents, cracks, or pressure dings (hard boards)

  • Abrasions or leaks (inflatable boards)

  • Loose or rusting hardware

  • Worn deck pads

  • Fin damage or misalignment

Addressing problems early ensures better performance and safety.

4. Protect Your Board From the Sun

UV rays are one of the biggest enemies of any SUP board. Prolonged exposure can fade colors, damage deck pads, and weaken material.

Protect your board by:

  • Keeping it in the shade whenever possible

  • Using a UV board cover or bag

  • Never leaving it on a hot car roof longer than necessary

This is especially important for inflatable SUPs, as heat can increase internal pressure.

5. Maintain Proper Air Pressure (Inflatable SUPs)

Inflatable SUPs require a little extra attention.

Tips for proper pressure:

  • Only inflate to the recommended PSI

  • Release some air if the board will sit in the sun

  • Never store an inflatable board fully inflated for long periods

  • Inspect valves for debris and proper sealing

Maintaining correct pressure extends the life of the seams and PVC.

6. Care for Your SUP Fins

Your fins are essential for tracking and stability—so keep them in top shape.

Proper fin maintenance:

  • Remove fins before transporting or storing

  • Rinse fin boxes and fin screws

  • Check for bent or cracked fins

  • Store them flat to avoid warping

A damaged fin can affect your board’s handling more than you might think.

7. Store Your SUP Board Properly

Whether you have a hard board or inflatable, correct storage is crucial.

For Hard SUP Boards:

  • Store indoors whenever possible

  • Keep it off the ground and out of direct sunlight

  • Use padded wall racks or ceiling mounts


  • Never store your board standing on its tail for long periods

For Inflatable SUP Boards:

You can store them either inflated or deflated.

Deflated storage:

  • Ensure the board is completely dry

  • Roll loosely to avoid creases

  • Store in a cool, dry location

  • Keep it away from sharp objects and pests

Inflated storage:

  • Release a little pressure

  • Keep it out of sunlight and heat

  • Store on a soft surface or padded rack

8. Use a Board Bag for Extra Protection

A padded SUP bag protects against sun, scratches, and dings—especially during travel.

Choose a board bag if you:

  • Transport your board frequently

  • Store it outdoors or in a garage

  • Want to prolong the life of the deck pad and paint

It’s one of the easiest ways to keep your board in good condition.

9. Transport Your SUP Safely

Good transport habits prevent accidental damage.

  • Use high-quality roof racks or soft racks

  • Tie down securely with SUP-friendly straps

  • Avoid overtightening (can dent hard boards)

  • Pad the board to prevent strap marks

10. Keep Your Gear Clean Too

Don’t forget to maintain your:

  • Paddle

  • Leash

  • Pump (for iSUPs)

  • Life jacket

  • Dry bags and accessories

Clean, dry gear lasts longer and makes paddling safer.

Final Thoughts

With just a little routine care, your SUP board can stay in top condition for years. Regular cleaning, proper storage, and mindful transport are the keys to protecting your investment—and enjoying smoother, safer paddling every time you hit the water.
