Use a wire brush to scrub the grill clean to remove old food particles that have been burned on. Once you've removed the larger pieces, go over each part of the grill with a grill brush and give the grill a good scrubbing. Empty out old ashes from the bottom of the bowl. When you're finished cleaning the grill, remove it from the braai and set it aside so you can light the fire. Stuff the bottom of the chimney starter with a piece of newspaper. Fill the chimney starter with as much wood or charcoal as you can fit. A braai needs a good, hot, large fire, so you need to start with a lot of fuel. When the chimney starter is full, use a barbecue lighter to light the newspaper in the bottom of the starter. Light it in multiple places around the starter. Once the fire is started, it will begin to spread and the charcoal or wood will burn down. Continue burning the fire in the chimney starter until the wood turns to embers or the charcoal turns gray. When the wood or charcoal is ready, pour the embers into the bowl and spread them out evenly with charcoal tongs. This will ensure that there aren't any cool spots, and that the steak cooks evenly on the grill. Concentrate the coals in the center of the bowl so the heat will be directly below where the steak is cooking. Carefully place the grill back into the bowl of the barbecue. If your grill has multiple racks, place the grill on the lowest one, nearest to the fire. Let the grill sit over the coals for 10 to 20 minutes to preheat. This will ensure the steak starts cooking as soon as you lay it on the grill. Ideally, you want the grill to be 2 to 6 inches (5 to 15 cm) from the bed of embers. When the grill is good and hot, use the wire brush again to give it a final scrub.

Q: Spend some time walking the streets in your area. Talk to civilians, just to get to know them and to introduce yourself. When people know the police officers in their community, they'll have a better relationship with them. You'll have a better sense of the community, that will help you protect it and resolve any issues. There are lots of ways for police officers to make a positive impact in their community outside of their regular work. Think of these as opportunities to strengthen ties with the residents of your area, and to help them build trust in their police force. Try things like: Running a toys for tots drive. Hosting "Shop with a Cop" events at holidays and back-to-school times to help children and families who are financially needy. Volunteering to visit schools, community organizations, religious centers, and other locations to meet people and talk about the work that police officers do. To best serve your community, you need to know as much as possible about it. Talking to individuals face-to-face will tell you something about what's important to them, and what they're concerned about. Getting a big-picture view of your community will also help you serve them with sensitivity. Look at census data and other sources to learn things like: What is the average age in my community? What age range do the majority of people fall into? What are the gender, race, and ethnicity breakdowns of the population? What is the average household income in the area? Serving a diverse community is the reality for police officers. It's important to identify biases that may impact your thinking so that you can overcome them in order to make good judgments in your police work. Biases, when unchecked, can lead to problems like racial profiling. Evidence shows that they can be overcome with proper training. Ask your superiors to host a workshop on diversity to help officers. Invite experts trained in the areas of diversity and biases to come and speak to your force. Sometimes, it's necessary to withhold information from the press, especially for ongoing investigations. Appearing unnecessarily secretive, however, will make it harder for people to trust the police force. If you can give the media the information they request, do so. If you can't divulge information for any reason, tell them something like "I can't comment on that right now, because the investigation is ongoing. However, I promise to release that information to the public as soon as I am able."
A: Get out there and talk to the people in your community. Take part in community events. Study the demographics of your community. Learn about biases and how to overcome them. Be as forthcoming as you can with the media.

Article: These mild acids are especially effective at removing rust stains. If you use lemon, you can either squeeze the juice onto the stain or gently rub the stain with a lemon wedge. Alternatively, pour a little white vinegar on the stain. While lemon juice and vinegar are both fairly gentle, they should not be left sitting on your ceramic for too long. Allow the stained area to soak only as long as necessary, or you might risk etching the surface or your sink, which will make it harder to clean in the future. Try wiping the stained area with a gentle sponge or cloth after half an hour or so to see if the stain is ready to come off. Don't use anything too abrasive. The soft side of a kitchen sponge or a washrag should work for this purpose. While it may be tempting to reach for a Magic Eraser, melamine sponges actually work like a very fine-grained sandpaper, and can scratch up your sink. After using any kind of acidic cleanser on your sink, you should carefully rinse it away with water. Make sure there isn't any residual lemon juice or vinegar sitting in your sink, gradually eating away at the ceramic.
Question: What is a summary of what this article is about?
Apply lemon juice or vinegar to any stained areas. Allow the cleanser to sit for a while. Wipe down the stained surface. Rinse thoroughly.
