Article: A spark plug that is not damaged will appear light grey or possibly tan. There should be no buildup on the sparking surface of the plug. If you purchased new spark plugs, their colors should be fairly similar. A good spark plug will not need to be replaced. If you have been having a misfire in the cylinder with a good spark plug, there may be an issue with the plug wire. Try replacing it to see if that solves the problem. Carbon fouling often occurs when your vehicle's engine is running too rich. Running too rich means there is too much fuel in the air/fuel mixture when it is ignited by the spark plug. Look for black soot on the sparking surface of the plug. A black, dry soot may develop on the plug when the engine is running too rich. You may be able to clean the soot off of the plug and avoid having to replace it. Wipe it down with a rag or spray it with Brake Cleaner to clean it. You will need to bring your vehicle to a mechanic to diagnose why it is running rich. If there is oil leaking in your engine down past worn piston rings or through the valves on your cylinder head, the spark plug may be oil-fouled. Look for wet motor oil on the plug itself. Oil fouled plugs will be wet, whereas carbon fouled plugs will be dry. You will need to address the oil leak to prevent fouling more spark plugs. An oil leak into the engine can cause significant issues. Bring your vehicle to a mechanic for diagnosis and repair. If you have been having overheating issues with your engine, you may burn out a spark plug. Look for blistering on the insulator tip of the spark plug or signs of heat damage such as melted plastic or burned metal. A heat damaged spark plug will have to be replaced. Overheating issues may be caused by worn out or insufficient levels of coolant. Add coolant if your vehicle is low, otherwise you may need to drain and flush your radiator. A severely worn spark plug is simply a plug that has been in use for too long. Older vehicles that have never had their spark plugs replaced may experience spark plug failure without fouling them in the ways listed above. Severe wear can cause a spark plug to come apart as you remove it. You may also see signs of eroded connections or cracking plastic. Severely worn plugs must be replaced.

Look for light grey or tan metal on a good spark plug. Identify signs of carbon fouling. Check for wetness on an oil fouled plug. Look for blisters or burning. Check for signs of severe wear.
Article: For many people, sun exposure worsens acne. In any event, by reducing the threat of sunburn you'll eliminate one possible source of red skin! Choose products labeled "oil-free" or "noncomedogenic" to avoid further clogging your pores. The less you have touching your face, the less likely you are to introduce bacteria to your already-troubled skin. Wear hair away from problem areas, avoid tight clothing, and refrain from resting your hands or objects such as telephone receivers on your face. Vitamin E is an antioxidant; it can repair skin and keep it safe from additional damage. Your body does not produce vitamin E on its own, but it can be absorbed through digestion or through the skin. Its anti-inflammatory properties mean it can reduce redness on your skin. In addition, research suggests vitamin E is expelled from the body through the same substance in your skin that clogs your pores. This means you may naturally clear your pores by consuming vitamin E; the extra vitamin E may push clogs out of your skin. Sunflower seeds, almonds, spinach and other leafy greens, pumpkin, red peppers, mangoes, avocados, swordfish, and peanut butter are all good sources of vitamin E. A water-soluble vitamin that works best in tandem with vitamin E, vitamin C regulates your skin's production of collagen cells. It also boosts your body's immune system, reducing your body's inflammatory response to the bacteria that cause acne (and thus reducing redness). Cantaloupe, citrus fruits, kiwi, mango, papaya, pineapple, berries, watermelon, broccoli, Brussels sprouts, cauliflower, green and red pepper, spinach and other leafy greens, cabbage, sweet and white potatoes, tomatoes, and winter squash are all good sources of vitamin C.

Use an oil-free moisturizer containing sunscreen. Keep hair, clothing, and other irritants off your skin. Consume foods containing vitamin E. Eat a diet rich in vitamin C.
Article: If someone gave you a gift card that you want to use for your iTunes purchases, you can enter its code into your iPhone in order to apply it to your next purchases. iTunes gift cards take precedent over your normal payment method, so any purchases made after entering your gift card code will use your gift card (until you've used up your gift card). You will need to scratch the foil off of the back of your gift card before you can view its code. Tap the iTunes Store app, which resembles a white star on a pink background. It's at the very bottom of the screen. When prompted, type in the password you use to log into your Apple ID account, then tap Sign In. It's in the middle of the screen. Using the on-screen keyboard, enter the code that's on the back of your gift card. It's in the top-right corner of the screen. As long as the gift card's balance is sufficient, any song you purchase will use your gift card's balance rather than using a credit or debit card: Tap Search, then tap the search bar at the top of the screen. Type in a song's name. Tap the price of the song. Scan your Touch ID or enter your Apple ID password when prompted.
