The benefits of regular stove cleanings include better fuel efficiency, flame control and no rust or corrosion. While there is no set schedule, you should clean it when it’s dirty or after a boil-over that causes buildup in the burners.
Annual cleanings are recommended before storing your stove at the end of camping season. Under most conditions, stoves can be wiped out with warm water and dishwashing soap and then dried before storing.
For a deeper cleaning, here are a few suggestions:
- If there has been a boil-over, remove the screw from the center of each burner and lift off the burner rings and bowl to check the manifold for fluid or food debris. If there is a build-up, clean it with dishwashing soap and warm water before rinsing with clean water.
- If the stove has a significant amount of grease and dirt build-up inside the case or on the grill or burners, you can take the stove to a car wash and use a high-pressure hose. Don't use any type of tire, oven or engine cleaner because it can damage the paint on the inside of the case and the metal of the grate and manifold.
- If a stove has been cleaned with any type of water hose, turn the stove upside down to ensure all the water is removed. Any water left inside the manifold can cause it to rust and disturb the flow of fuel to the burner, preventing the stove from burning properly.
- After cleaning, proper storage of your Coleman® stove is also important. Put it into a plastic bag, sealing with a twist tie to prevent spiders or other insects from crawling in the unit, which can block the fuel and airflow.
With a liquid fuel stove, transfer as much fuel as possible out of the fuel tank and back into the fuel can to prevent a lacquer buildup on the tank's fuel tube. Keep in mind that storing a liquid fuel appliance with fuel in the tank can eventually cause a buildup on the fuel tube, which restricts fuel flow to the generator and burner.
When it's time to take out your stove, remember to oil the pump cup on the tank's pump plunger at least twice a year with a light machine oil. This allows the cup to seal against the inside of the pump barrel and insures the pump will work smoothly and push air into the tank properly.
