Problem: Article: A metal scraper is a good place to start, though if you're worried about scratching the surface, you can use a plastic one. The polyurethane should peel off fairly easily as you move along. The paint stripper should have done the hard work. Scrape in the direction of the wood grain. Scrubbing against the grain can damage the surface of the floors or furniture. Plus, if you add any scratches, it will look like the grain of the wood. In curved or decorative areas, a scraper won't work as well. Instead, scrub it with a metal brush, as the bristles will get in all the nooks and crannies and remove the polyurethane. After wash is a solvent you use after paint stripper. Its purpose is to clean up the end of the polyurethane, as well as remove the paint stripper you used. Just use a paper towel to rub it in. You don't have to leave it on for any time. Just rub it on until the rest of the polyurethane comes up. If the first round didn't take off enough of the polyurethane, go through the process again. Apply another layer of paint stripper to the area, and then scrape it down again, checking to see if that completed the process. After you've removed most of the polyurethane, sand down what remains. You can simply use fine steel wool. You can also use 150-grit sandpaper. The sandpaper will smooth it out and take off the last of the polyurethane. The after wash should have taken off most of the polyurethane, which is why you shouldn't need a heavy-duty sandpaper. Always rub with the grain. Take the water and rags to a hazardous waste disposal unit in your town, along with leftover stripper. Do not throw rags and chemicals directly into the trash or sewer. Contact your city to find your local waste disposal center.
Summary: Use a scraper to scrub it down. Use a steel brush to get into small areas. Rub the polyurethane down with after wash. Repeat as needed. Sand the surface to remove polyurethane. Soak your discarded rags and steel wool in water to avoid fires.

Problem: Article: Cast-iron skillets are recommended for the best results, but you can use any frying pan you have. If you are using a cast-iron pan, you can speed up the heating process by placing it into a preheated 350° F (176° C) oven for about 20 minutes and removing it with an oven mitt. Starting with a piping hot cast-iron pan is key. Add a small amount of cooking oil to the pan. Don't use more than 1 tablespoon (0.5 ounces). If your oil smokes, your pan is a little too hot. Take it off the burner for a couple minutes and try again. When the beads of oil spread evenly and shine, the pan is ready for cooking! Place your patty in the middle of the pan and let it cook. Your burger patty will sizzle once it hits the pan and it might even smoke. This is good. Cook it for about 4 minutes. Resist the urge to poke and prod at your patty. Don't push it down into the pan. Leaving your patty alone will allow for it to form a delicious thick crust that will seal in the flavor. Once and only once, when you see the underside starting to turn brown, flip your burger. Cook for an additional 4 minutes on the other side.  The last few minutes of cooking is the perfect time to add a slice of cheese. Place a slice of cheese onto your patty and let it get perfectly melted in the last minute or so of cooking. Your burger is medium-rare at an internal temperature of 130 to 135° F (55 to 57° C). Your burger is medium at an internal temperature of 135 to 150° F (57 to 65° C). Your burger is medium well at an internal temperature of 150 to 165° F (65 to 74° C). Your burger is well done at an internal temperature of 165° F (74° C) or greater.
Summary: Preheat your skillet. Test the heat of your pan. Grill your burger. Flip your burger.

Problem: Article: You'll need a pair of dumbbells in a weight that you can lift 8 - 10 times before feeling muscle fatigue. Doing this exercise 2 times weekly will build up strength in your biceps and eventually help you get better at pull-ups.  Stand with your feet shoulder-width apart and the dumbbells at your sides. Curl the dumbbells up to chest height, bending your elbows. Lower the dumbbells back to your sides. Repeat for 3 sets of 10 curls. This exercise simulates a pullup, but it's a lot easier to do because most of your weight is on the ground. It's an excellent way to start building up enough strength to do a pullup. You'll need either a dip bar or a sturdy mop or broom positioned across two chairs. Here's how to do it:  Lie down with your neck positioned under the bar or broom. Bend your legs and keep your feet against the floor. Grip the bar with your palms facing out. Lift your chest toward the bar as far as possible.  Lower back down to the ground and repeat. You'll need a pulldown machine to do this. It's another effective way to strengthen your upper body and make you better at pull-ups.  Stand in front of a pulldown machine and grip the bar. Sit down and pull the bar down to your collar bones. Keep your shoulder blades down and back and lean backward while you do this. Repeat. This is like a pullup, but instead of gripping the bar with your palms facing out, they should face toward you. This position is generally easier and exercises the biceps and upper back. This position is a great compound bicep exercise, and a good exercise to do when you're training to become better at pull-ups.  Grip the bar with your hands facing you. Pull your bodyweight off of the ground, crossing your feet beneath you. Keep lifting until your chin reaches the bar. Lower yourself back down.
Summary: Do biceps curls. Do reverse pushups. Do pulldowns. Try chin-ups.
