To clean an ignition key hole, you'll need contact cleaner and lubricant. The process involves spraying, drying, and lubricating.
Here's a step-by-step guide:
- Clean it Up: Hold the ignition switch upside down. Using a contact cleaner with a red straw/nozzle, spray liberally into the key slot. Also, spray into the small hole at the base of the stem (if your ignition has one). This helps to dislodge dirt and debris.
- Let it Dry: Allow the contact cleaner to fully evaporate. This ensures that any dissolved grime is removed and doesn't interfere with lubrication.
- Lubricate: Apply a lubricant specifically designed for locks and ignition systems. This will help the key turn smoothly and prevent future buildup. A dry lubricant, like graphite powder or PTFE-based lubricant, is generally recommended, as it won't attract as much dirt as a wet lubricant. Avoid using oil-based lubricants, as they can trap debris and worsen the problem.
Important Considerations:
- Type of Cleaner: Always use a contact cleaner, not a general-purpose cleaner, as contact cleaner is designed to be safe for electrical components.
- Type of Lubricant: Use a lubricant specifically for locks or ignition systems.
- Avoid Over-Lubricating: A small amount of lubricant goes a long way. Excess lubricant can attract dirt and create a sticky residue.
- Safety First: Disconnect the car battery if you're concerned about electrical shorts. Although, this is typically unnecessary with proper contact cleaner use.
