That's right–a normal writing eraser. You could also use a Magic Eraser or similar cleaning product, but a normal pink eraser is actually very effective at cleaning up scuff marks. Mix 1 cup (about .25 liters) of white vinegar in bucket or bowl with 4 to 5 cups (0.9 to 1.2 liters) of very warm water. Vinegar is a key, powerful cleaning agent that is all-natural to boot. Dilute it with water to make it easier to use and less harsh on the nose. You can also use a few drops of mild dish soap in lieu of vinegar. Don't try and do the whole thing at once–water left on wood generally doesn't do good things. Once you have an area clean to your liking, immediately dry it. While forgetting once or twice won't likely cause any damage, it can cause issues for sensitive woods or finishes. Get into the dustiest, dirtiest spots with a wet cotton swab. Soak the swab in your dilute vinegar or soap solution first. You may need a couple, but they're great for the harder to reach areas.

One-sentence summary -- Attack any tough scuff marks with an eraser. Make a diluted vinegar to clean the baseboard. Soak a sponge in the vinegar solution and scrub a section. Dry off the wall with a clean rag as you work. Scrub out the corners of the baseboards with a cotton swab.

Q: Use a bucket that is only for the aquarium so that you don’t get other chemicals and contaminants in the water. If the tap water is not the right temperature, you can leave it out for a few hours at room temperature. Always add a water conditioner (with Stress Zyme if you need some slime coat protection) to get rid of the chloramines/chlorine. Not doing so will result in damage to fish gills and a slow death! If you are using straight tap water, you will need to put some neutralizer in it and let it set for a minute. Test it again before putting it into the tank. This is better than pouring it in because it won’t upset the fish or the decorations.
A: Fill a bucket with tap water that is the same temperature as what is in the tank. Add any necessary additives, like salt for a saltwater tank, or nitrates/potassium. Check the pH balance of the water. Use the siphon to put the water back into the tank. Test the water again after an hour to make sure it has the right chemical balance. Finished.

Article: You can often tell when a headlight blows out while you’re driving, but confirm which bulb has actually blown out by leaving your headlights on and getting out of the vehicle to check.  Then get back in your vehicle and turn on your high beams.  Some vehicles use a single bulb for both high and low beams while others do not.  If the high beam on the same side is also out, it may be one bulb.  You do not need to purchase specific bulbs for each side, but identifying which is the blown out bulb will help you to replace it without having to start the vehicle again. If neither the low or high beams work on the same side, there could also be an electrical issue preventing the bulbs from getting power. It’s important that you get the correct bulb for your year, make and model vehicle.  Try asking the clerk at your local auto parts store to look it up in their system, or try checking the auto maker’s website for the code indicating which headlight to use.  Headlight codes are usually comprised of letters and numbers like H11B or D3S. You can find the proper code for your vehicle at websites such as www.lightbulbs4cars.com as well. Swapping a low beam bulb can require varying amounts of work.  While some cars may require no tools at all, others may require specialized tools to help remove portions of the trim under the hood, or even the bumper and grill.  Refer to the service manual for your specific vehicle for a comprehensive list of tools required for the job.  Most vehicles require only a screw driver or nothing at all to gain access to the headlight housing.  After referring to the service manual for your vehicle, visually inspect the area around the headlight in yours to ensure it looks the same as it does in the manual. If you purchased your vehicle used, flat head screws may have been replaced with Philips head screws or other components may have been swapped out during repairs by the previous owner. Be sure you remember which side of the car has a blown out low beam bulb before disconnecting the battery.  To disconnect it, use a hand or socket wrench of the appropriate size to loosen the nut holding the ground cable onto the negative terminal of the battery.  You don’t need to remove the nut, just loosen it enough to slide the cable off of the terminal, then tuck the cable to the side of the battery.  Tucking the cable will prevent it from popping up and coming into contact with the negative terminal of the battery. You will not need to disconnect the positive terminal.

Article: Cut the butter into small cubes first, then put it into a small saucepan. Place the saucepan onto the stove, and turn the heat up to medium. Wait for the butter to melt, stirring it occasionally. Stir the butter and flour constantly as it's cooking to prevent scorching. Stir the sauce as you pour the milk so that it blends in. Once you have the milk stirred in, place the saucepan back onto the stove, and set the heat back to medium. Cook the sauce until it comes to a boil. Stir it often. Take the saucepan off the stove, and stir in part of the cheese. Be sure to scrape the bottom of the pan from time to time to ensure that everything mixes in evenly. Save the remaining ½ cup (50 grams) of cheese for later. If you have not already done so, wash and peel the potatoes, then cut them as thinly as your can. Spread a third of them across the bottom of your dish, overlapping the edges slightly. Repeat the potato, salt, pepper, and sauce layers two more times. Spread it as evenly as you can over the top of your potatoes. When the cheese bakes, it will form a melted, crusty layer on top. They are ready when they turn tender and golden. If the top of your potatoes start to burn, cover the dish with a sheet of aluminum foil; this will allow the potatoes to continue baking without getting burnt. They are a great size dish for just about any meat dish. They are also easily transported, making them perfect for picnics, potlucks, and parties.

Melt the butter in a saucepan over medium heat. Stir in the flour, then cook it for about 2 minutes, or until it starts to bubble. Take the saucepan off the stove, then slowly stir in the milk. Cook the mixture over medium heat until it starts to boil. Stir in 1½ cups (150 grams) of cheese. Spread a third of your potatoes across the bottom of the dish. Season the potatoes with salt and pepper, then pour a third of the cheese sauce over them. Sprinkle the rest of the cheese on top. Bake the potatoes, uncovered, for 1 hour. Allow the potatoes to cool slightly before serving them.
