Article: First of all, this method is much easier than it sounds. Fill a plastic bucket with enough water to submerge your rusted object and mix one tablespoon of baking soda or washing soda per gallon of water. Use hot water, the warmer the water, the better. Mix well until it dissolves. The electrolysis process will take the rust from the object you want to clean and eventually attach itself to this metal. You want the sacrificial anode to be big enough so that half of it is submerged and the other half the half onto which you attach your positive terminal is above water. This is very important. A steel can works fine as your sacrificial anode, provided it is big enough to be partly sticking out of the water. Rebar is good too. Make sure the can anode is magnetic to avoid confusing it with aluminum. You do not want to use aluminum or stainless steel as your sacrificial anodes for electrolysis. Connect a negative terminal (black in color) from a battery charger to a rust-free section of your rust-covered object for a good connection. You may have to manually scrape away some rust to achieve this. Fully submerge the rusty object, taking care to keep as much as possible of the wire out of the water. Caution: Make sure this rusted object does not touch the anode to prevent an electrical short-circuit (a short). Next, you will need to connect a positive terminal (red in color) from the battery charger to the sacrificial metal. Remember not to submerge the sacrificial metal completely, or you'll risk eating away at the positive terminal, which you don't want to be eaten away. If the sacrificial metal is completely submerged, consider using another wire as a mediator/connection between it and the car battery charger lead to keep the charger terminal and connection dry. The electrolysis process will gradually start working away at the rust. Let it sit for 12-20 hours. Caution: If you ever want to check the status of your rusted object, be sure to turn off and unplug the battery charger first. You will see bubbles rise to the surface and muck gather at the surface. Both of these things are normal. When taken out, your rusted object should be rust-free, but still in need of some cleaning. Use a Scotch Brite pad to remove any sludge on the object and a bristle brush to clean those harder to reach spots.
Question: What is a summary of what this article is about?
Set up an electrolyte solution. Use a different, sacrificial piece of steel as an anode. Connect a negative terminal. Connect a positive terminal. Plug in the car battery charger and turn it on. Unplug the car battery and remove the leads from your objects.

You can remove an ingrown hair by inserting a sterile needle into the pimple and using sterilized tweezers to catch the hair and pull it out; however, inserting a needle into your skin can lead to infection if the needle is not sterile, so it is best to check with your doctor first before trying this method. It is best to try to clear up the ingrown hair by keeping it clean before you try using a needle to remove it. If the ingrown hair is on your face, you risk scarring and disfigurement. If you aren't comfortable doing this yourself, you can ask your doctor to remove the ingrown hair for you. Dead skin cells can build up over an ingrown pimple and cause the skin to look thicker and darker. Retinoids can get rid of dead skin cells, which may make ingrown pimples go away faster. Retinoids are available by prescription only, so ask your doctor if you are interested in trying them. Ingrown pimples can become red and inflamed, which may make them more noticeable. Using a steroid cream will not get rid of ingrown pimples, but a steroid cream can reduce redness and swelling. As a result, your ingrown pimples may blend in with the rest of your skin a little better. Because ingrown pimples are prone to infection, antibiotic ointments may help to control infections. If you develop a severe infection from an ingrown pimple, then your doctor may prescribe an oral antibiotic. Make sure that you follow your doctor's instructions for using antibiotic creams and pills. Most ingrown hairs will go away on their own and your doctor may advise you to just leave it alone. If the ingrown pimple bothers you, then you can cover it with a loose band-aid until it heals. While you are waiting for the ingrown pimple to get better, do not tweeze, wax, or shave the area, as this can cause further irritation.
