Buy a funnel whose stem fits snugly with the fuel opening of your tiki torches. Pour your fuel into the funnel slowly to avoid spills. Avoid overfilling the fuel reservoir by keeping an eye on the fuel level as you fill. If you don't have a funnel, pour the fuel in a thin stream directly into the torch. Avoid pouring the fuel into another container and then trying to fill the torch, which can cause spills. An overfilled fuel reservoir will overflow and leak down the sides of the tiki torch. Let the kitty litter sit on the spilled fuel until it is clumped and firm to the touch, at least 10 minutes. Throw away the soiled kitty litter in its own garbage bag away from other flammable materials. Use a commercial-grade cleaning solution suited to the spill surface to remove any remaining fuel residue. Keep the area well ventilated after cleaning so it can dry out completely. Typically you can apply cleaner to the stain with a damp towel and let it air dry. Use a match or lighter to ignite the wick of your tiki torches when you're ready to use them. Avoid lighting them long before your event to keep from wasting fuel. When you want to extinguish your torches, place the snuffer cap completely over the wick and let the torch go out naturally. Remove the snuffer cap when the flame is out, and let the wick cool down completely. Once the wick is completely cool, replace the snuffer cap. This will protect your wick from the elements if you store your tiki torches outside. How long your torches take to cool down will depend upon how long they were lit. Hold your hand close to the torch to feel if it is still giving off heat, if you're unsure. Make sure your torches are firmly staked into the ground if you intend to keep them outside. Keep an eye on the weather forecast, as temperatures below 32 (0 C) will cause the fuel in your tiki torches to freeze. If you store your tiki torches in a garage or shed, use a tether to secure your torches upright. It is safe to let any unused oil stay in the torches while they are in storage. If the temperature hits freezing, either empty the fuel reservoirs of your outdoor tiki torches or bring them inside to a warmer area.

Cotton is king when it comes to comfortable underwear because it is breathable. That means moisture won't be trapped in the fabric so your undies won't get as sweaty and you won't have to worry as much about bacterial and yeast infections. Because of the possibility of yeast infections, cotton underwear is a particularly good option for women. Cotton underwear is also less likely to cause chafing or rashes. While cotton underwear's breathability makes it more comfortable, it doesn't always look smooth under clothing. For a slimmer, fit, opt for undies made from a stretchy, synthetic material, such nylon, Lycra, or spandex. Make sure that the crotch is lined with cotton, though, to ensure that you're comfortable. Consider the type of underwear labeled as "seamless" or "no-lines." They don't have any elastic in the hips or leg openings, making them ideal for fitted garments. A cotton lining in the crotch is important for another reason: it's breathable. If the crotch lining is synthetic, then you risk trapping moisture, which can lead to infections. Silk underwear definitely has a luxurious, sexy feel, but it doesn't breathe as well as cotton. That means there's a greater chance of moisture being trapped in your underwear, which can lead to infections. Only wear silk underwear on special occasions for the most comfortable feel. This also goes for other types of fancy underwear, such as lace. While lace underwear does often have a cotton lining, it's not very comfortable or durable.
