Cleaning and Maintaining a Kayak

A proper clean: mild soap and a soft brush

For a proper clean, use warm water and a mild soap with a soft brush or sponge. Avoid harsh solvents and abrasive pads on plastic and gelcoat. A mild cleaner removes the greasy film that builds up around the cockpit and the waterline. Rubber hatch covers benefit from an occasional wipe with a silicone-based protectant, which keeps them supple and sealing well; leave them slightly loose when storing so they do not deform.

Moving parts need periodic attention

Moving parts need periodic attention. Rudder and skeg cables should slide freely without resistance. Flush them with fresh water, and if a skeg jams with grit, work it back and forth gently rather than forcing it, since bending a cable is easy and annoying to fix. Check pedal assemblies, foot brace tracks, and seat hardware for salt buildup and loose bolts. Stainless hardware still corrodes in salt, so inspect and replace anything showing rust streaks or pitting.

Deck lines and bungees are safety equipment

Deck lines and bungees are safety equipment and they age from sunlight, not from use. Perished bungee loses its stretch and cord goes stiff and pale before it breaks, usually at the worst possible moment. Replace them when they look faded or feel brittle, which is an easy job with a few metres of cord and a lighter to seal the ends. While you are there, check the security of every deck fitting and pad eye, and confirm that grab toggles at bow and stern are sound, since those are what you will grab after a capsize.

Hull repairs depend on the material

Hull repairs depend on material. Light scratches on polyethylene are cosmetic and can be left alone; a shallow fuzz of plastic can be carefully trimmed with a sharp blade. Deeper gouges that go more than a millimetre or two deserve attention, and plastic welding with a compatible rod is the proper fix. Composite boats with gelcoat chips are repaired with a gelcoat repair kit, and any damage that exposes fibres should be repaired before the layup starts to absorb water. Small cracks in either material spread, so fix them promptly rather than at the end of the season.

Test for leaks periodically

Test for leaks periodically. Dry the inside of a compartment, paddle a normal trip, then check for water. A wet compartment usually means a hatch seal, a bulkhead seam, or a fitting that has worked loose. Bulkhead seams can be resealed with a flexible marine sealant. A slowly leaking hatch is easy to live with and easy to forget, but it also means your dry storage is not dry and your flotation is compromised.

Build a simple maintenance schedule

Build a simple schedule. After each trip: rinse, drain, dry, hatches open. Monthly during the season: check deck lines, bolts, cables, and hatch seals. Twice a year: a full inspection with the boat on trestles in good light, looking at the hull from every angle. Keep a small kit of spare bungee, cord, a few bolts, sealant, and tape. Kayaks that get this treatment routinely last twenty years and more, and they sell well when the day comes to move on to something different.

Frequently asked questions

How do I maintain a kayak? Rinse the hull, cockpit, hatches, and fittings after every trip and dry with hatches open; monthly, check deck lines, bolts, cables, and hatch seals; twice a year, do a full inspection in good light.

Why do I need to rinse my kayak after paddling? Fresh water leaves silt and organic material that encourages mildew and can spread invasive species; salt water leaves crystals that attack metal fittings, stiffen fabric, and degrade rubber.

When should I replace kayak deck lines and bungees? When they look faded or feel brittle, because they age from sunlight rather than use and tend to fail at the worst moment. It is an easy job with a few metres of cord and a lighter to seal the ends.

How do I fix scratches in a plastic kayak? Light scratches on polyethylene are cosmetic and can be left or the fuzz trimmed with a sharp blade. Deeper gouges need plastic welding with a compatible rod, and small cracks should be fixed promptly because they spread.

Cleaning and caring for an inflatable kayak

Inflatable kayaks need the same rinse as hardshells, but drying is far more important because they get folded and packed away. Rinse the outside, the floor, and the seams with fresh water, open any drain valves, and wipe out sand that collects along the inside tubes. Grit left in a fold acts like sandpaper every time the boat is packed and unpacked.

Dry the kayak completely before folding it, ideally inflated or partly inflated in the shade, and pay attention to the underside of the floor and the seams where water hides. Packing a damp inflatable is the most common cause of mildew smells and stained fabric. Keep the valves clean and free of sand, and close the caps so grit does not get into the valve seat, which can cause slow leaks.

Sun and heat are the other enemies. Avoid leaving an inflated kayak in direct sun on a hot deck, since air expands as it warms and raises the pressure in the chambers. If the manufacturer recommends a UV protectant for its material, apply it occasionally, and store the boat loosely folded in a cool, dry place rather than tightly rolled in a hot garage.

A simple routine for kids' and youth kayaks

Youth kayaks are usually smaller polyethylene boats, which makes them easy to maintain and a good chance to teach kids the routine. After each outing, have them help rinse the hull and cockpit, tip the boat to drain it, and check that the seat, footrests, and any carry handles are still secure. Small hands tend to leave snacks and sand behind, so a quick wipe of the cockpit is worth adding.

Check the paddle and the life jacket as part of the same routine, since they are the parts kids use hardest. Rinse both, let the life jacket dry fully before storing it, and look for torn straps or buckles that no longer click firmly. Store the kayak on its side or upside down, off the ground, and out of direct sun so it keeps its shape for the next child who grows into it.
