How to Clean a Spear Gun

Time to go hunting.

Spear guns must operate in an unforgiving environment. Saltwater is very corrosive and will take its toll on all things mechanical. Inspecting and cleaning of your spear gun is important if you expect it to operate at the bottom of the ocean. It is frustrating to have a big fish lined up, ready to shoot, only to have your spear gun fail because of improper upkeep. Take good care of your spear gun and it will be ready when you find that big fish.

Things You'll Need

• Tap water from garden hose
• WD40
• Tung oil
• Silicone spray
• Sand paper

Instructions

1. 

   Immediately after use, spray the spear gun thoroughly with tap water from the garden hose. Use high pressure and make sure the water reaches all parts of the spear gun. Allow the gun to dry in the sun until all the water has evaporated.

2. Inspect rubber bands for any cracks or defects. Replace the bands if any cracks or defects are found. Spray the bands with silicone spray, and then rub the spray in with a dry cloth. While inspecting the bands, pay close attention to the attachment points and also check the nocking wire for any signs of wear.

3. Inspect the receiver for wear and proper operation. Spray the outer and interior of receiver with WD40. In addition to lubricating the trigger and safety mechanism, WD40 will also displace any water left inside the receiver.

4. Check the stock for any cracks, rough edges or splinters. Repair any defects found and lightly sand any rough edges. Rub the wood with Tung oil every other month to help preserve the wood.

5. Inspect the spears for straightness and for signs of rust. Check the nock notches and barb for damage. Lightly sand rust spots and wipe down the entire spear shaft with WD40. Store the spear gun out of the sun.

Tips & Warnings

• Spear gun bands will deteriorate quickly if left in the sun. Store in a shaded area.

• Use caution when working with spear guns. Never cock a spear gun out of the water.
