Article: A mouthpiece puller is a handy device that is solely intended to pull stuck mouthpieces out of brass instruments. They can be used for small and large instruments, so they are versatile enough to use on trumpets, trombones, tubas and so on. These are available online or in music stores. The most common mouthpiece pullers are:  Bobcat Mouthpiece Puller: This is the least expensive, costing about $40. This one has two screws that need to be tightened simultaneously when using it. Ferree G88 Mouthpiece Puller: This is a more expensive option, costing about $100. It is bulkier, but it only has one T handle that needs to be screwed in when being used. DEG Magnum Mouthpiece Puller: This is usually the most expensive puller, costing about $130. It is very similar to the Ferree. You should have a level working space. Be careful to not put it near the edge where it can fall. Alternately, you can do this on the floor, especially if you have a large instrument. You may want someone to help you by gently holding the instrument still while you operate the mouthpiece puller. One end of the mouthpiece puller will go against the instrument at the point where you insert the mouthpiece. There are usually grooves or other U-shaped areas where your mouthpiece will fit into the puller. Read the manufacturer’s instructions to ensure you are using the mouthpiece puller correctly. Depending on the type of puller you are using, tighten the screws (on the Bobcat mouthpiece puller) or the T handle (on the Ferree G88 mouthpiece puller). Turn the screws evenly, steadily and slowly. The mouthpiece should start to move out of the instrument. Once the mouthpiece puller has loosened the mouthpiece, you should be able to gently twist and pull to get it free. It should come out smoothly. For mouthpieces that are really stuck, use a rubber mallet to tap the puller when it is tightened up. This might enable you to turn the screws a little more to help move the mouthpiece. The mouthpiece end that inserts into your instrument should be round and clean. There should be no rust or other debris on it. Look for dents and an oval or squashed shape by holding the mouthpiece at eye level or comparing it to an undamaged mouthpiece. If your mouthpiece is misshapen at all, use a trueing tool to return it to its correct shape. This tool looks like a skinny T and has a somewhat pointed end. To use, insert the tool into the end of your mouthpiece. Tap it very gently with a rubber mallet (not a hammer!). The tool will force the mouthpiece end to become rounded.

Problem: Article: Using a stiff-bristled brush or dry sponge, remove as much dirt from the pants as you can while they’re still dry. Use long, sweeping strokes, being careful to avoid spreading dirt to clean areas. Shake the pants out thoroughly when you’re done.  Brush down the pants outdoors to keep from making a mess inside your home. It’s important to treat stains as soon as possible so that they’ll have less time to set up on the fabric. Mix together roughly two parts hydrogen peroxide and one part liquid dish soap and shake to combine. Both of these ingredients contain active stain-fighting agents and will be instrumental in lifting the worst of the stains prior to laundering. Keep a bottle of hydrogen peroxide solution mixed up so that you’ll have a ready supply on hand to treat a dirty uniform after each game. Mist the pants liberally on both sides, focusing on areas where dirt and discoloration is the heaviest. Then, use your brush to work the solution further into the fibers of the garment where they can continue working on the stains.  Reapply fresh solution after chipping away at the stains with the brush. If the stains are very pronounced, turn the pants inside out and spray and brush the opposite side of the fabric as well. Give the solution time to take effect before moving on to other deep-cleaning methods. You might be surprised how well the initial treatment can work on ground-in dirt, grass and blood stains.  Leave the pants on a flat, dry surface as they sit, like a countertop or the ironing board. The longer you let the stain-fighting solution work, the better the end result will be.
Summary: Brush off excess dirt and debris. Combine hydrogen peroxide and a mild detergent in a spray bottle. Spray the stain-fighting solution onto the pants. Allow the solution sit for 20-30 minutes.

You want to be sure it is physically healthy and doesn't have any hereditary problems. Watch the guinea pig move. It should run and walk without difficulty. Look at the shape of the guinea pig. Make sure it is neither too skinny or too fat. Also, look at the pig's legs and feet to make sure its foot pads aren't swollen or bleeding and that the legs are straight along the bone. Lastly, look at the skin. There should not be any bald spots. Look in its eyes, ears, and nose. If there is discharge in the ears or nose or film on the eyes the guinea pig might have some kind of infection. Another sign that the guinea pig might be sick is if it doesn't eat. It should eat frequently, so even if you meet a guinea pig for a short period you should see it eat. To do this, you will need to inspect the genitals. Also check that they are over six weeks old and aren't pregnant. Just because a guinea pig is healthy doesn't mean it has the personality to be your perfect pet. Play with the guinea pig for a bit and gauge its personality. Ask him or her if the pig has ever been sick and if its parents were healthy. Chances are good that they will tell you the truth and its always better to ask than not to.
