Summarize the following:
Before you start, you should unplug the dryer to prevent accidents. The plug is usually located behind the machine. Test it to be sure that you have unplugged it correctly. Make a paste with baking soda and a few drops of water. Then, spray the inside of the drum with bleach water or a bleach cleaning product like Clorox. With a scrubbing sponge, put the paste onto the area you want to scrub and start scrubbing. When you're done, rinse with a wet rag. This should help remove some of the dye. Make bleach water by mixing 1-2 cups of bleach with 1 gallon (3.8L) of water. You'll want to wear kitchen gloves while you do this, as the bleach and baking soda can be very harsh on your skin. Now to remove the rest of the dye. Soak some old towels or a large number of rags in more of the bleach water that you mixed previously. Just get them thoroughly soaked, they should not need to be in the water for more than 5 minutes. Wring the towels out, to remove excess water. Run the towels through the fluff cycle on the dryer for about 30 minutes. This should have removed most if not all of the dye. However, if more remains, you can repeat the towel process a few times to see if any more can be removed. Once you've removed as much of the product as you can, mix a bucket with soapy water. Use this water and a clean cloth to wipe down the inside of the drum. With the dryer rinsed out, run a load of old towels through a cycle in the dryer to remove any ink which might still remain.

summary: Unplug the dryer. Start by scrubbing with bleach water and a mild abrasive. Soak towels in bleach water. Wring out the towels. Run the towels through the dryer. Repeat as needed. Rinse the drum. Run a cycle with old towels.

Make sure you add cup (118 grams) of sea salt for every 1 gallon (3.8L) of water. Mix the sea salt in thoroughly and wait until it dissolves and the water is clear. Wait 2 to 3 hours until the water is at room temperature before adding it to the aquarium. Purchase pre-mixed saltwater from pet stores. between 8.0 and 8.4. Use pH paper to test the pH of your water daily. To increase pH, add 1 teaspoon (4.9mL) of baking soda for every 5 gallons (19L) of water. To decrease pH, add peat moss. Buy pH paper and peat moss from pet stores. Dip ammonia into the water regularly to make sure levels are undetectable. Similarly, use nitrate strips to make sure levels are less than 10 ppm. Purchase both ammonia and nitrite testing papers from pet stores, big-box suppliers, or online stores. Pour a sample of the habitat water into a container and insert a hydrometer. Once it stops floating, check the waterline and read the corresponding specific gravity. When specific gravity levels are too high, replace saltwater with freshwater 10 percent at a time to lower it. If specific gravity levels are too low, raise it by replacing up to 10 percent of the freshwater with saltwater at a time. Hydrometer scales read "specific gravity," which is the ratio of the liquid's density to the water's density. Make sure replacement water is the same temperature as aquarium water. Don't alter specific gravity more than 0.001 per day. Anything more can cause shock to your hermit crabs. If necessary, adjust salinity over the course of 3 to 4 days.

summary: Fill your tank with chlorine-free saltwater. Keep the water pH Test your water for nitrite and ammonia regularly. Keep the specific gravity between 1.021 and 1.028.

Visit your local library or a bookstore to begin reading about electronics. Even older books have a lot of information about electrical circuits and how they work. Use it to study the basics before you begin building your own circuits. Try books like Make: Electronics, The Art Of Electronics, or Foundations of Analog and Digital Electronic Circuits. For more resources, search online for informative websites and digital book copies. Search your phone's Play Store to find a number of informative, hands-on apps. Some apps teach you the basics of electronics, while others let you design your own circuit board using a touchscreen. For example, try Electronics Basics or ElectroDroid. An electrical current consists of electrons, which are the negatively charged particles in atoms. In a current, the electrons flow from a negative source, such as a battery terminal. Then, it flows around the circuit and returns to the positive terminal. You can think of it like a faucet. When the faucet turns on, "water" is pushed through until it reaches the end of the pipe. Voltage is a measurement of the force needed to make a current flow through a circuit. In a circuit, the electrons accumulate near the battery's negative terminal. Energy is needed to get the current to flow through the circuit, and this measurement is the voltage. Think of it as pressure in a water tank. When water is drained from the tank, the pressure goes down and less water flows out. Resistance slows the current in a circuit. Different materials inhibit electricity more than others. You will need a stronger electrical current to pass through insulation than a conductive material like metal. This increases the voltage. For example, imagine water pipes of different sizes. Water faces more resistance flowing through the smaller pipe due to the lack of space. Electrical diagrams and schematics use symbols to denote components. Before you can copy one to build your own circuit, find out what the symbols mean. Search online for a list of symbols used as shorthand in diagrams. The straight lines are wires. A battery is represented by a + sign followed by a long and short straight line. Diodes, for example, are represented by triangles. Resistors are represented by squares or jagged lines.
summary: Read books to learn the fundamentals of electronics. Download a phone application to study electrical engineering. Study how a current travels along a wire. Read about the voltage in a circuit. Study the resistance factor of different objects. Read circuit diagrams to understand the notation.
