Lubricate Spark Plugs & Other Parts
For part of your car repair and maintenance, you can use WD-40 to remove carbon residue, and keep moisture away from spark plugs and spark plug wires.
Yes, you can spray carb cleaner (or carburetor cleaner) inside the spark plug hole. This'll help dissolve the hardened debris and loose materials in the spark plug well. After that, you can remove the filth with a compressed air can.
Oil is a vital lubricant in a well-functioning engine, but your spark plugs are not the place it should be. Oil on spark plugs can indicate much larger engine problems. So you'll want to watch for common signs indicating excess oil on your spark plugs.
Silicone spray or powdered graphite are the most easily found lubricants, or Master Lock 2300D or 2305 lock lubricant should help the lock work more smoothly.
It is mandatory to maintain a balanced spark gap between the two electrodes. A short gap can weaken the spark plug and a wider gap might prevent the spark from firing at all or may misfire at high speeds. Before creating a balanced gap between the electrodes, refer to the user's manual for a balanced figure.
To safely clean a spark plug, you should use a wire brush or spray-on plug cleaner specifically designed for this ignition part. You can also use a sturdy knife to scrape off tough deposits. Note: NEVER clean a spark plug with a shot blaster or abrasives.
Drive out moisture from flooded engines. From tractors to cars to lawnmowers, WD-40® Multi-Use Product can displace excess moisture from flooded engines. Make sure your engine is turned off, then spray the original WD-40 formula into the carburetor before re-starting the engine.
Yes, it's perfectly safe to use. Despite what some of the doom-mongers are spouting on here. Yes there are better things to use but if WD40 is what you've got then just go ahead. Just don't use too much and have a rag handy to catch any run-off.
Teflon-based dry lubricant is preferred by some locksmiths over other options, like graphite or WD-40. It's ideal because, besides lubricating your lock, it repels water and dust. That means that once you fix a lock with this type of lubricant, you can expect the lock to be in good shape for a long time.
Warning – Do NOT apply copper grease/slip or anti-seize to the plug threads, copper grease is only for used on old fashioned black spark plugs which don't feature a corrosion-resistant zinc plating.
Because it's fast-drying and leaves no sticky residue, WD-40 Specialist Contact Cleaner is great for use on circuit boards, switches, spark plugs, and tape heads, removing any oil, dirt, dust or flux residue that cause current leakage and component failure, and protecting against condensation in damp conditions.
But as good as silicone-based lubricants are, there are still some limitations to their use under certain circumstances. Silicone lubes cannot be used alongside silicone sex toys, as the mixture between the two silicone products will cause the toy's material to swell, deform, and become gritty over time.
NGK spark plugs are installed at the factory dry, without lubrication or anti-seize. Anti-seize can act as a lubricant, altering torque values up to 20 percent, increasing the risk of spark plug thread breakage and/or metal shell stretch.
Tighten the spark plug finger-tight until the gasket reaches the cylinder head, then tighten about ½ – ⅔ turn more with a spark plug wrench.
