Depending on how old the stove is and how much rust and grime has built up on its outer surface, this may take some serious scrubbing. Focus on applying the wire brush to the top of the cast iron stove, and to other areas where rust is visible. Rust is especially likely to have built up if you've rested metal on the top of the cast iron stove. People often leave tea kettles on top, or use the heat of the stove to cook pans of food or raise bread dough. These uses will contribute to rust and grime on the stovetop. Once you've cleaned off the majority of the rust and built-up grime with the wire brush, you can use sandpaper to get of any remaining rust and to generally clean the outside of the cast iron stove. Start with a coarse grain sandpaper, such as 150-grit. Then move on to a more fine-grained sandpaper, even one as fine as 400-grit. Sand the entire outer surface of the cast iron stove. This will remove any marks or scratches made by the wire brush or by the coarse grain sandpaper. After you've finished sanding the stove, you can clean any lingering smudges of ash or dirt off of the exterior surface using a vinegar cleaning solution. Spray the solution across the surface of the cast iron stove, and wipe it clean using a few old rags. Let the stove dry before you light the next fire inside. To make the vinegar cleaning solution, find an empty spray bottle, and combine inside two parts water to one part vinegar, then add a small amount of dish soap. Shake the spray bottle, and the cleaning solution will be ready to use.

summary: Scrape rust off with a wire brush. Apply sandpaper to the exterior of the stove. Wipe the stove down with a vinegar cleaning mixture.

You'll need to know exactly what coin you're looking at to determine its specific value. Modern coins will include a date of issue printed on the front or back of the coin itself. They will probably also name the country of origin. If the information printed on the coin is printed in a language you can't read, consult a world coin reference book or website. These will include images that will help you match your coin. These guides can also be used to help you determine how old coins without a printed date are. If you cannot find the coin in a book due to lack of identifiers, try to determine general area (i.e. Sinosphere, Islamic Countries, Core African). Broadening your search first may help you narrow in on the correct country. The value of a coin is greatly affected by its condition. Higher quality coins are generally more valuable than ones that are blemished or dirty. Coins that were never used are known as uncirculated. Coins are rated from "mint" (perfect) condition, all the way down to "poor" (dirty or damaged). If you have a coin that you think might be rare or valuable, don't attempt to clean it yourself. Take it to an expert to have it cleaned without damaging it and lowering its value. If a coin is severely damaged, it might just be worth the value of the metal itself. Some websites will make values for some coins freely available. Check with an professional organization like the Professional Numismatics Guild. Look up your coin according to its date and origin, and you may be able to find its current value. A number of factors (including condition and current demand) impact the amount a coin can actually be sold for, so use the value you find online only as a ballpark figure. If you can't find the value of your coin online, consult a reference such as the Standard Catalog of World Coins, or the Guide Book of United States Coins. These references are especially useful because they may list several values for a particular coin: The "book" value (a generally accepted value of the coin) The "buy" value (what a dealer would pay to buy the coin from you) The retail value (what a dealer would sell a coin to a customer for) The wholesale value (what a dealer might sell the coin to another dealer for, especially when several coins are sold together) The value of coins can go up and down, since they are driven by interests that can change. When lots of people want to buy a certain type of coin, the value may go up. Rare or unusually fine coins are often more valuable than common ones. Finally, commemorative (special issue) coins may also be especially valuable. Take these values into account when calculating the value of your coin. For instance, you may have a type of coin that is not especially rare. However, if it is in mint condition, and most coins of that type are not, its value may be higher than the normal "book" value.

summary: Pin down the coin's origin and date. Inspect the coin to determine its condition. Check coin value lists online. Consult a coin value book. Account for any special factors.

The addition of oil helps preserve the paste when it's put in the fridge or freezer. The actual amount you add can be adjusted to your flavor preference. Any neutral-flavored oil, like canola or avocado oil, will work in place of vegetable oil. Using a small amount of vinegar will have a similar effect, but may affect the flavor. Use a dry glass jar with an air-tight seal. Avoid adding any water to the paste so it stays fresher for longer. Label the container with the date so you know how long you've kept the ginger paste. Don't let the ginger paste sit at room temperature as you cook. Once you've scooped out the desired amount, close the jar tight and put it back into the fridge. Keeping the paste cold is essential for keeping a fresh taste. Measure out 1 tablespoon (15mL) of the paste into the wells of an ice cube tray and put it in the freezer. Once the cubes are frozen, transfer the cubes to an airtight freezer bag. Label it with the date you made the paste so you know how long you've kept it. Frozen ginger paste has a shelf life and can be used for up to 3 months. Ginger paste can be added to stovetop meals immediately, but thaw it in the fridge for 5 minutes if you plan on using it in baked goods.
summary: Add 2 tablespoons (30ml) of vegetable oil. Store the paste in a glass container for 1 month in the fridge. Return the paste immediately to the fridge after you use it. Freeze the paste in individual servings in an ice cube tray.
