Open the fuel door when you wash, wipe the cap and filler neck with an all-purpose cleaner, and dry the area.
Why it gets grimy
Fuel drips, dusty hands and road film all concentrate around the filler neck. Because the door is usually closed, the grime builds up unnoticed.
Cleaning steps
- Open the fuel door before washing
- Wipe the cap, neck and surround with all-purpose cleaner on a cloth
- Clean the inside of the door itself
- Dry everything before closing
