In one sentence, describe what the following article is about: Once a spill or leak has occurred, immediately press a clean, dry towel into the mattress to absorb the liquid. Replace your towel once it becomes soaked. Try to get as much of the liquid up as possible. If your mattress is wet from bodily fluids, like urine or blood, you'll need to use an enzyme cleaner. Other stains can be treated with a mixture of 2 parts hydrogen peroxide to 1 part liquid dishwashing soap. Brush the stain remover into the mattress with a toothbrush, then wipe it up after 5 minutes with a cool, damp cloth. If only a small amount of liquid got on the mattress, like if you spilled a glass of water, you can quickly dry it with a hairdryer. Aim the hairdryer at the wet spot and use a warm, not hot, setting. Keep the hairdryer moving for best results. If rain blew in from the window, for example, a portion of your mattress may be soaked. Turn on a wet/dry vacuum and run the nozzle over the wet parts of the mattress in long, even strokes to suck up the liquid. Disinfect the vacuum nozzle first, as you don't want to touch your mattress with a nozzle that's been stuck into cobweb-filled corners of the garage. Simply wipe it with an antibacterial wipe, inside and out, and let it dry. If your mattress was moved during a rainstorm, for instance, it's bound to be pretty wet. Spread a layer of clean kitty litter over the wet areas of the mattress. Then, cover the kitty litter with a towel and firmly press the kitty litter into the mattress. Vacuum up the kitty litter with a wet/dry vacuum. If the mattress is still wet, spread a fresh layer of kitty litter on the mattress and allow it to sit for 1 to 2 hours. Then, vacuum it up. After you've soaked up as much of the liquid as possible, take the mattress outdoors and set it in the sunlight. Choose the hottest, sunniest spot on your property. Be sure to spread plastic sheeting or an old blanket beneath the mattress so it doesn't get dirty. Sunlight has the added benefit of killing bacteria in your mattress, as well. Open as many windows as possible to get the air moving around the mattress. If both sides are wet, stand it on one end or lean it against a solid surface so air can flow freely around it. Set up a fan and/or a dehumidifier, depending on what you have handy. Direct the fan at the mattress to increase the air circulation. Unfortunately, time is essential for drying a mattress. If the mattress is soaked, like from a ceiling leak, it's best to make alternative sleeping arrangements for the night, as it may take up to 24 hours to fully dry. Covering the mattress with sheets and bedding when it's wet will lead to mold and mildew growth, which is hazardous to your health.
Summary: Blot the area with clean, dry towels. Treat any stains. Dry small spots with a hairdryer. Use a wet/dry vacuum to soak up excess liquid. Press clean kitty litter into the mattress to absorb liquid. Dry a soaked mattress in direct sunlight, if possible. Provide plenty of air circulation if drying indoors. Expect to wait a few hours.

INPUT ARTICLE: Article: Squash is a game played with two players (although you can practice on your own). The game begins when one player serves the ball from the serving square. The server hits the ball against the far wall of the squash court so that it bounces back into the other half of the court, opposite the servers square. The goal for both players is to return the ball to the far wall, only allowing one bounce on the floor before hitting it. When returning the ball to the far wall, it can bounce off the the side walls of the court, but not the floor. The last person to successfully hit the wall during a volley wins a point. You must hit the far wall of the court in between an upper line and a lower line, indicated on the wall. The bottom line has a strip of tin along it, so that you can hear when a ball hits it. A squash match is awarded to the player who wins the best of 3 or 5 games. Each game goes to 11 points, with the first player to reach 11, by at least two points, winning. If a player reaches 11 points but the other player has 10 points, for instance, then the game continues until one player gets ahead by two points. Unlike in tennis, either player can gain a point on any play. All that matters is that the person who does not return the volley loses the point. The player that earns each point follows their point by becoming, or continuing to be, the server. Position your hand so that there is a "v" between your thumb and pointer finger, but put the rest of the fingers close to the pointer finger. Grip your hand around the handle of the racket firmly but not so hard that your hand is stressed.

SUMMARY:
Review the rules of the game. Review how to score a game. Learn how to hold the racket correctly.
