In one sentence, describe what the following article is about: You can even buy a special cleaning brush, but a toothbrush will work just as well. Don’t use the toothbrush you use for brushing your teeth. Try to find a hard bristled toothbrush. Dishwashing soap is a good choice, but you can also use hand soap. Anti-bacterial soap also works. Gently brush the mouth guard or retainer. Pay special attention to the pockets of dirt and plaque. Make sure all of the soap comes off. Feel the mouth guard to make sure none of the soap remains. Rinse it really well to avoid any unpleasant irritation of the oral mucosa from leftover soap. If your mouth guard or retainer is not in use, it should be in a case. This protects it from getting damaged and away from pets (who often like to chew on it.)
Summary: Get a toothbrush specifically for the purpose. Put a small amount of soap on the mouth guard. Use lukewarm water on the toothbrush to create suds. Rinse under warm water. Put into your mouth or into a case.

Problem: Article: Chances are that most sites that list available proxies are also blocked at your school. Building a list at home will help you find more sites to use. A proxy site is a site that fetches the blocked website for you, and displays it through the proxy site. This means that the filter software never actually sees you going to the blocked site (YouTube), just the proxy site. Your search result should list quite a few sites that index available proxy sites. Your school's network administrators actively block new proxy websites as they appear, meaning that a large number of the sites you find will already not work. Grab sites from multiple different proxy lists. You just need to be able to access your list from the school's computer. If it is blocked, move on to the next site until you find one that is unblocked. youtube.com into the URL field. Click the button to open the site. A proxy will increase the time it takes for sites to load since the traffic has to be routed through the proxy server. This means videos will take longer than normal to play. Also, make sure that your proxy doesn't block scripts, or else YouTube won't load.
Summary:
Open a search engine on your computer at home. Search for "proxy list". Find a website that lists a lot of available proxies. Make a list of a dozen proxy sites to try. Email the list to yourself or write it down. Visit the first site on your list. Enter . Wait for YouTube to load.
