Article: For pens that are made of silver, sterling silver, or plated silver, use a polishing cloth with a little dab of silver polish. If your pen has etching on it, you can use some silver polish with a toothbrush. This will work the silver polish into the grooves of the etching. Many fountain pen exteriors are made of platinum, palladium, stainless steel or chrome. These metal finishes can be buffed with a soft cloth. Older pens may have a celluloid finish, which is a finish that predates modern plastic. Just use a soft cloth to clean the celluloid. If your pen has a lacquer or painted surface, use a soft cloth to clean it. Do not use any chemical or abrasive cleaners on this pen, as these will damage the finish. Fine resin finishes can be vulnerable to cracks and scratches. Use a soft cloth to clean these types of finishes.

Use silver polish on a pen made of silver. Use a soft cloth to clean hard metal finishes. Use a soft cloth to clean celluloid, lacquer, and fine resin finishes.

Problem: Article: Sandpaper won't work as well on the places where the compound has piled up a bit, so start with your drywall knife. Just run it along where you have larger bits of compound built up, scraping them up as you go.  Go around the whole room first with the knife before working on sanding. Buildup is common in the inside and outside corners, so make sure to scrape these areas well. Start in the corner where two walls meet. Sand outward so that you taper the mud down to the wall. In other words, sand along the corner in broad strokes, then slowly move those strokes outward toward the edge of the mud. You can also try wet sanding, which cuts down on dust. Dip a sanding block in warm water and wring it out thoroughly before using it on the wall. Rinse your sponge out when it becomes coated in white goo. You can use either the sanding sponge or the full sandpaper to go over the areas with screws and even them out. These areas usually only need a quick sanding. You'll also have seams along the wall where pieces of the drywall meet. Go over it with sandpaper (220 grit) first to quickly even it out. Swipe back and forth over it in broad strokes. Smooth it out again with your sanding sponge. Keep checking with the light to see if you miss areas. You don't need to send very hard. You're not scraping burnt rice off the bottom of a pan. You just want to smooth out any ridges and bumps in the dry wall, so you have an even surface. Don't sand down to the paper. Also, make sure you're only sanding the high parts. You'll fill in the low points with another coat of mud. You don't need to try to sand them smooth. If you notice there's dust on the wall from your sanding, you can use a dry paintbrush on it. Quickly run the brush over it to loosen up the dust, so it doesn't get into your primer when you start painting. You may also want to vacuum the wall or wipe it down with a damp cloth to ensure that there is no sand left on it. Clean up the area by vacuuming as much as you can with a Shopvac then folding the dropcloths to take outside. Make sure you use the proper filters and bags for drywall when preparing the Shopvac. Otherwise, the dust will just come out of the back. If you're renting at a shop, ask what supplies you'll need for cleaning up drywall.
Summary: Scrape off the extra bits of mud/compound. Taper with the sanding sponge. Go over screws. Sand the seams. Use light pressure. Run over it with a dry paintbrush. Clean up carefully with a Shopvac.

A standing hamstring stretch is an exercise that can help treat sciatica pain by stretching and lengthening the hamstring (back of your thigh) muscles.  Stand in front of a low table or sturdy box.  Place one heel on the table or box on it while standing straight and keeping your foot flexed and toes pointed to the ceiling. Slowly bend over at the waist, making sure to keep your back straight.  Try to touch your toes, as much as you can until you feel a slight stretch in your hamstrings.  If you're not able to touch the toes, rest your hands on your shin or knee for a more comfortable position. Hold the stretch for 20-30 seconds, then return your foot to the floor.  Repeat this stretch two to three times per leg. Flexing and bending your back forward can alleviate pain from sciatica.  This helps to alleviate the irritation or impingement on the nerve.  Start by lying on your back on the floor on an exercise mat or carpet.  Bend both of your knees while raising them towards your chest. You will be able to feel a light stretch at the lower part of your back.  Hold your knees at a position that you feel a light, yet comfortable stretching sensation in your lower back. Hold the stretch for thirty seconds, and repeat four to six times. Although a common pose to yoga, the child's pose is another exercise that can cause the comfortable, forward bending stretch that can help alleviate sciatica pain.  Sit on your knees on a carpet or exercise mat.  Lower your forehead to the ground and rest your head comfortably. Stretch your arms out in front of you and over your head and just allow them to relax, palm-side down on the mat or carpet in front of you. Hold this position for 30 seconds and repeat four to six times as you're able and feel comfortable. The piriformis stretch or "ankle over knee" exercise helps to  loosen the piriformis muscle and increases its flexibility. Increased piriformis flexibility reduces the pressure on the sciatic nerve underneath. It is important to stretch the piriformis because, while it is very small and deep, it runs directly over the sciatic nerve.  Increased tension in this muscle will cause compression of the sciatic nerve (possibly all the way down the leg).  Lie down on your back on the carpet or exercise mat.  Bend both of your knees at a 90 degree angle and keep feet flat on the floor. Place the left ankle on top of the right leg's knee. Your legs should now form a figure four pattern. The outer side of the left ankle should rest comfortably on the right leg’s front thigh. Grab the back of your right thigh and slowly pull your thigh forward. You should feel a stretch deep in the left butt muscle. This is the piriformis being stretched. Keep your butt on the ground the whole time and hold the position for 30 seconds. People older than 40 years old should hold the position for 60 seconds. Switch legs and repeat two to three times per leg.
