How to clean your lawn mower’s gas cap

DescriptionVideos

Here’s a frequently asked question:

“How do I get the crud off of my lawn mower’s gas cap?”

The fuel cap (a.k.a. gas cap) on lawn mowers, chainsaws and other gasoline-powered outdoor power equipment is a magnet for dust, dirt, grass and other debris.

Many people use a dry rag to remove the “crud” but I’ve found that the most efficient way is to use a paint brush. By simply brushing off the particles, this reduces risk of dirt or other contaminants getting into the fuel system.

Check the equipment’s owner’s manual for information about how to properly clean this area.

Bonus cleaning tips for lawn mower owners:

  • After every use, be sure to clean the lawn mower’s undercarriage. Use a garden hose to remove grass clippings and debris build up in the undercarriage. Important: ALWAYS turn off the mower and disconnect the spark plug before cleaning any part of your lawn mower.
  • Use a clean air filter: The air filter has the important job of preventing dirt, dust and debris from entering the carburetor and engine. It should be cleaned or changed every 25 hours or once per mowing season. Pleated, paper air filters must be replaced. Foam air filters can be cleaned with hot water and a small amount of detergent and then left to air dry before being saturated with engine oil and reinstalled.

Bonus cleaning tips for chainsaw owners:

  • A paint brush is also a great tool for removing wood chips and dust from chainsaw chains. It’s important to clean the chain before adding fuel or chain oil to chainsaws.
  • A few times per season (depending how frequently you use your chainsaw), use compressed air to clean the chainsaw’s carburetor.
