Keep It Clean
After each paddle, you need to clean and dry out your kayak inside and out, especially after being in saltwater. You can wash your kayak with mild or organic dish soap and water. Dry off your kayak or let air dry before storing.
Protect It from the Sun
Apply a UV-protective coat to your kayak at the start and end of the kayak season. If you use your kayak often, applying a coat midseason isn't a bad idea. Do not store your kayak in direct sunlight.
Carrry, Don't Drag
When transporting your kayak, carry it. If you drag your kayak, you can weaken the kayak and cause scratches, holes and other damage.
Cover Your Kayak
Covering your dry kayak when not in use can protect it from the elements and from insects or other critters.
Store your kayak upside down on its stern, if possible, to put the least amount of stress on it. If you have a plastic kayak and can't stand it up straight, put it on its side. You can hang any other kayak upside down.
