No matter whether you sleep on your back, stomach, or side, adding pillows can help provide support. Basically, you want to add a pillow anywhere there's a space between your body and the mattress. For instance, if you sleep on your stomach, which is the worst position for your back and posture, place a flat pillow under your stomach to provide support. Choose a flat pillow or no pillow for your head. If you sleep on your back, place a small pillow behind your knees, and choose a supportive pillow for your head. If you sleep on your side, place a pillow between your knees and pull them up towards your chest. Pick a pillow for your head that keeps your spine straight, or use a full body pillow. Avoid turning at your waist while you are in bed. Instead, keep your back straight and your stomach muscles tight, and turn your whole body when you want to reposition yourself. While you may have heard that one mattress or another is best for a healthy back, the truth is whatever works for you is best. Choose one that lets you rest comfortably and wake up pain free. Remember to replace your mattress every decade or so. If your mattress isn't providing the support you need, add a board between the box springs and mattress, which should keep it from sagging.

summary: Provide support for your back with pillows while sleeping. Turn your body as 1 unit when laying down. Sleep with good posture by choosing a comfortable mattress.

A fiber brush is useful because it can easily enter the grooves of the record to remove dirt. Additionally, the type of fiber easily drains static electricity which is responsible for attracting dust. To use, spin the record slowly while holding the brush over the vinyl. Special brushes can be purchased at your local music store or online. Use the brush to clean your records both before and after each record use. Don't forget to clean the dust off of the brush between uses too. Avoid using a T-Shirt or towel as this can damage the surface of your vinyl. There are pre-formulated cleaning products available both online and at local music stores, but you can also make a safe and affordable cleaner at home. Combine distilled water, isopropyl alcohol, and a couple drops of laundry detergent #without fragrance or dyes#, spray onto the vinyl, and use a microfiber cloth to wipe in a circular motion until the vinyl is dry. Combine 12 oz distilled water, 2 oz alcohol, 2 drops free and clear laundry detergent, into a spray bottle. It's important to use distilled water because it doesn't have any minerals that could be harmful to the record. Vinyl record vacuums provide a deeper clean than brushing and cleaning products alone. The vacuum sucks the debris out of the grooves with as little friction as possible. In addition, vacuums are able to apply a thin layer of cleaning fluid which dissolves oils and further protects the record. Each record vacuum is different so consult included with the device to learn to operate the device correctly. As an added bonus, the vacuum also helps to dry the record in an even fashion.

summary: Use a carbon fiber brush. Try using a cleaner. Purchase a vinyl record vacuum cleaner.

Storing a lead-acid battery at a very low charge state can cause permanent crystal formation (sulfation) that reduces capacity. Lithium-ion batteries at low charge can develop copper structures that short the battery, making it dangerous to use. The exact recharge instructions depend on the battery design. Follow these guidelines if you do not have access to manufacturer instructions: Lead AcidRecharge to full whenever voltage drops below 2.07 volts / cell (12.42V for a 12V battery).One charge every six months is typical. Lithium Ion (Li-ion)Recharge to 3050% capacity whenever voltage drops below 2.5 V/cell. Do not recharge if voltage drops to 1.5V/cell.One charge every few months is typical. If your rechargeable batteries drop to low charge levels for more than a few days, they will likely require special treatment before you can use them again: Lead AcidThe battery will usually recharge, but with permanently reduced capacity. If a small lead acid battery fails to recharge, apply a very low amount of current at a high voltage (~5V) for two hours.Anti-sulfation devices are not recommended without an experienced operator. Lithium Ion (Li-ion)The battery may enter "sleep mode" and fail to recharge. Use a charger with a "boost" feature, taking care to apply the voltage with the correct polarity.Never boost a battery that falls below 1.5V/cell for a week or more, as it is permanently damaged and dangerous to use. Nickel-based (NiMH, NiZn, NiCd)No major issues. Some types may require charging and fully discharging a couple times to return to full capacity.For large scale use, consider a battery analyzer that can "recondition" the battery.
summary: Recharge lead acid and lithium-ion batteries periodically. Restore discharged batteries.
