Spray brake cleaner on the plug and wipe it down. Spray some brake cleaner on the plug and threads, then use a clean rag to wipe away any remaining dirt or debris. If your spark plugs are really dirty, you can use the brake cleaner and wire brush together to tackle stuck on grime.
Technically, yes, you can clean spark plugs, however, in most cases it's not worth it. We do not recommend it for a number of reasons. Ultimately, you won't get the same performance from a cleaned plug as from a new plug. Electricity discharges best from sharp edges.
A spark plug usually lasts about 30,000 miles, but cleaning them and maintaining them periodically lets your engine perform better and increases your plugs' lifespan. If you see rust, carbon, gunk, dust, or any type of buildup during the inspection, it may be time to clean them.
WD-40 Multi-use Product is ideal for cleaning spark plugs. Spray WD-40 Multi-use Product on a microfiber cloth and rub over the spark plug. You can even spray WD-40 directly on the spark plug & then wipe it down using a soft, clean cloth.
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.
Dielectric grease is a simple compound of oil and silica filler that's very hydrophobic and is excellent at sealing out moisture and preventing corrosion.
You can clean a fouled spark plug and reuse it, but it might not function as well after that. If your spark plug is too worn or dirty to clean easily, you'll need to replace it.
Soft, black, sooty dry deposits on plug indicate carbon fouling. Carbon fouling is an indication of a rich air-fuel mixture, weak ignition, or improper heat range (too cold).
It is the same process if you're curious about cleaning spark plugs with vinegar or petrol. With a wire brush, remove the carbon deposits from the plugs and soak the plugs in vinegar or petrol for a few seconds to remove the accumulated carbon deposits.
While the engine is running at the correct operating temperature, Increasing the engine RPMs helps the motor to burn-off carbon buildup within. The use of specialized fuel additives and fuel treatments will also aid the engine in removing these deposits.
Can I Spray Carb Cleaner Inside the Spark Plug Hole? 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.
Spark plugs are designed for long-term durability, meaning that they only need to be replaced between every 80,000 and 100,000 miles. However, they can become damaged earlier than expected and require replacements to avoid pricey engine repairs.
Two Common Mistakes While Changing Sparkplugs
Possibly the two most common mistakes made with handling sparkplugs---aside from installing the wrong type for your engine---is damaging the spark plug cables by pulling on them; and, misapplying dielectric connector grease to your plugs.
Flood the tip of the plug with rubbing alcohol and let it sit for one minute, gap-end upward. Scrub the entire tip of the spark plug with a soft brass or plastic brush, applying more rubbing alcohol as needed to keep the tip wet. Clean as deeply as possible in and around the tip.

Spark plugs are made to be self-cleaning. The heat generated by high engine temperatures allows the spark plugs to burn off anything that may be covering them.
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.
The most common signs of bad spark plugs include start-up trouble, rough idling, sluggish acceleration, declining fuel economy, engine misfiring, and engine knocking.
This silver or chrome-colored finish on the threads is designed to provide corrosion resistance against moisture and chemicals. The coating also acts as a release agent during spark plug removal. NGK spark plugs are installed at the factory dry, without lubrication or anti-seize.
Just about every spark plug manufacturer will recommend against putting any lubrication on spark plugs.
