In one sentence, describe what the following article is about: Despite the fact that ciao (chow) is perhaps one of the most universally known Italian greetings, it is used exclusively with friends and family who you know very well. Ciao is never used with strangers. You should also never use it with people who are older than you or in a position of authority – you'll be seen as rude.  You may also be familiar with the phrase ciao bella (chow BEHL-lah), which means "hello beautiful." This phrase is typically used flirtatiously, although it may also be used among friends. Be careful using it with acquaintances, however – they might get the wrong idea.  Ciao can be used both when you arrive and when you depart, as a "hello" or a "goodbye."  Salve (SAHL-veh) means "hi," and is generally appropriate in any situation. While many words and phrases in Italian are considered either polite and formal or casual and informal, salve is used in both contexts. If you've known someone for a long time and are very close to them, they will likely consider salve too formal. In that situation, you'd be better off using ciao. Bella technically means "beautiful," or even "nice," but young people in Italy also use it as a generic greeting, similar to ciao. This is relatively youthful slang, however, so avoid using it with people over 30, or if you are over 30 yourself. You'll sound immature.  Bella is often followed by an Italian word that means "guys" or "dudes," such as bella lì or bella zio. No one's going to look at you strangely if you simply say come sta. But if you want to sound a little cooler and blend in more with Italian friends your age, you might try come butta (KOH-meh BOOT-tah), which is a bit more casual. Avoid this type of slang in public settings, such as if you're greeting a server at a restaurant, even if they seem to be around your age or younger. In that setting, this phrase can be considered too direct and the person might take it as rude or even condescending.
Summary: Use ciao to greet friends. Greet a group of friends by saying ciao a tutti. Switch to salve if you're unsure about the context. Say bella when greeting younger people. Add come butta to ask the person "what's up" in Italian.

Problem: Article: Use a wire brush to scrub the grill grate, removing any traces of burnt on food from previous grilling sessions. Even if you cleaned your grill after using it, it is still a wise idea to clean it again, especially if it has not been used for a while. Scrubbing the grill grate also helps to remove other debris that could have gathered on it in between uses. Pour a small amount of canola oil onto a clean paper towel and rub the paper towel over the grate.  The oil creates a non-stick coating that will limit the amount of steak getting stuck to the grill as it cooks. In the absence of oil, you could also use aluminum foil. Cover the grill grate in aluminum and poke holes throughout the foil with the tines of a grilling fork. You must poke the holes in the foil so that enough heat can travel through. You should begin 20 minutes before cooking, and you need to prepare two areas of high heat and one cooler area.  Set the grill grate aside temporarily. Use a chimney starter to ignite a moderate pile of charcoal briquettes. Let them burn until they are covered in white ash. Dump the hot coals into the bottom of the grill. Use tongs with a long handle to carefully spread the coals. You should have two or three layers in one-third of the fire bed, and one or two layers in another third. The remaining third should have no coals. Return the grill grate to the grill As with the charcoal grill, begin 20 minutes before you plan on cooking. Turn all heat elements on as high as they will go. The grill must be very hot before you can add the steak.  To check a charcoal grill, hold your hand roughly 4 inches (10 cm) above the tallest flames. You should only be able to count to 1 before needing to pull your hand away. If you can tolerate the heat longer, the grill is not hot enough yet. For a gas grill, the temperature gauge needs to reach 500 degrees Fahrenheit (260 degrees Celsius) before it is ready.
Summary:
Scrub the grill grate. Coat the grill grate with canola oil. Preheat a charcoal grill. Alternatively, preheat a gas grill. Check the grill before beginning.
