In one sentence, describe what the following article is about: Apply a light oil that will not stain or dry the metal components. You can use commercial products such as WD-40, 3-In-One, Clean Streak, and Metal Brite. Use a clean rag to apply a thin layer of oil directly to the blade. Use as little oil as possible because a thick layer of oil may attract dust and debris. Leave the knife open and allow the oil to soak into the blade for two to three days. This should loosen up the rust spots and make them easier to remove. After two to three days, use the tip of a sharp knife to carefully scrape off the rust spots. You can also use a piece of steel wool. If you work slowly and carefully, you can remove the rust while leaving much of the original finish of the blade intact. You can purchase non-toxic rust removal products in hardware and auto parts stores, such as Evapo-Rust. These products are gentler than some of the other acid-based chemical solvents that you can use to remove rust. To use a product like Evapo-Rust, pour some of the product into a bucket and then immerse the knife blade in the solution. Leave the knife to soak in the solution for 30 minutes or overnight if it is really rusty. Rinse off the excess product and dry the knife with a clean, dry cloth. CLR is a commercial cleaner that removes calcium, lime, and rust from any metal surface. It is often used on old plumbing and appliances, but it can also be used to remove rust from a knife blade. Dip the blade of your knife directly into a solution of half CLR and half warm water. Avoid getting CLR on the knife handle, if it is made of anything other than metal (e.g. plastic, bone, wood, stone). Rinse the blade right away with cold water. Do not soak the blade in CLR for any longer than two minutes, as this may damage the metal. If stains persist, use CLR at full strength (not diluted with water), and rinse right away with cold water. CLR is a caustic substance. Clean your knife in a well-ventilated area, and use gloves when handling CLR. Do not mix CLR with other household cleaners, as this may cause a dangerous reaction. Do not use CLR on galvanized metal, as it may cause spotting on the zinc coating of the blade.
Summary: Oil the blade to remove light rust stains. Use a non-toxic rust remover. Try CLR for extra stubborn rust stains.

In one sentence, describe what the following article is about: Click or double-click the grey elephant app icon to do so. You should see the MAMP dashboard window appear. On a Mac, you can find the MAMP app icon inside the Applications folder. This will allow MAMP to skip using port 80 in favor of using the next free port. In virtually all cases, MAMP will use port 81 if port 80 isn't free. Doing so will allow MAMP to use its selected port. If you're on a Windows computer, Firewall will ask for permission to let both Apache and MySQL through. Click Allow on both prompts before you proceed. Skip this step on a Mac.
Summary: Open MAMP. Click Use next free port when prompted. Click Yes when prompted. Confirm any Firewall requests.

In one sentence, describe what the following article is about: Do not use a plastic comb or a comb with no handle. Your hot comb must be made of metal or ceramic so that it won't melt, and it needs a heat-resistant handle so that you don't burn your hand. Hot combs can be purchased at beauty supply stores or online. If you have a gas stove, hold the comb so that the teeth are just barely getting brushed by the top of the flames. For an electric stove, hold the teeth against the hot burner, and use medium to medium-high heat. After 30 seconds, test the comb before you use it by setting it on a white paper towel. If the towel turns brown, your comb is too hot and will damage your hair. Let it cool for a minute and test it again before using it in your hair. This test is very important, as your hair can burn or fall off if the comb is too hot. Remove the clip holding one of the bottom back sections of your hair. Give that section a quick comb-through with a normal plastic-tooth comb before using the hot metal comb. This prevents getting the hot comb stuck in your hair. Position the teeth of the comb on the hair near your roots. Do not allow the comb to actually touch your scalp, but get it as close as possible so you can straighten any new growth. Holding the section of hair out from your head with one hand, use the other to gently pull the comb all the way from the root through the ends of the hair in one quick motion. Avoid keeping the hot iron comb in one spot for too long, or you could scald your hair. If one pass-through didn't get it straight enough, you can go over it again with the hot comb. But don't do this more than one additional time, or you risk burning your hair. One pass should be enough for fine or medium hair. Two passes may be necessary for coarse or thick hair. After running the comb through your hair a few times, it will begin to lose its heat. Hold it over the flame or on the burner again, but remember that it's already slightly hot so it won't take as long to warm back up. Remember to test the comb on a white paper towel each time you heat it up to make sure it isn't too hot for your hair. Continue hot combing, working your way from the nape of your neck to the top of your head. Work from back to front since the back is the hardest spot to reach, and having the rest of your hair in clips will make it easier to see what you're doing.
Summary:
Use a ceramic or metal comb with a heat-resistant handle. Hold the comb over a stove burner for 30 seconds. Test the comb on a white paper towel. Loosen a section of hair. Place the comb close to your scalp. Pull the comb down through your hair quickly. Repeat on the same section of hair if necessary. Reheat the comb periodically. Comb the rest of your hair.
