Use a paint brush to loosen surface dust, then vacuum it up with a shop vacuum. You may want a few different size brushes to help you reach into all the nooks and crannies. If you don't have a shop vacuum, you can blow the dirt and dust away with a leaf blower. Go over the entire engine with the brushes and vacuum. The intake sits at the top of the engine and is usually made from aluminum, which can get stained and pitted. Rub a metal wire brush over the entire intake and any other aluminum parts, like lettering plates, to clean them. Be careful not to rub any hoses or sensors with the metal wire brush. Alternatively, you could use a rotating wire wheel to clean aluminum parts. Spray the engine bay with a weak stream of warm water before applying any cleaner to remove loose dirt and grime. Avoid spraying the covered electrical parts. Rinsing the bay first helps the cleaner to spread evenly and reduces spotting. Make sure you don't use cold water, which could crack the block. Diluting the cleaner or degreaser provides you with a more even clean. Use 1 part water and 1 part cleaner.  Spray the entire engine bay except for the covered electrical parts. Pay special attention to the firewall, fluid containers, hoses, and caps, which tend to build up grime. Products like Simple Green and Purple Power Degreaser work well for detailing engine bays. You don't want to use a high-pressure sprayer, or water may be forced into places it shouldn't go. Use a weak stream of warm water to rinse the grease and grime off the engine. If the engine bay still looks pretty dirty, spray more diluted degreaser, let it soak for 5 to 10 minutes, then rinse it away.

Prepare at least four custard dishes or small bowls. Spoon about 1/4 cup (60 ml) of prepared white frosting into each dish.  There are multiple ways to create orange frosting, but each one requires a base of white frosting. You'll need at least four samples of white frosting, but setting up six to twelve will allow you to experiment with more options. You should obtain at least four different food dyes: one orange, one red, one yellow, and one black. Consider getting additional hues of red and yellow for additional experiments. Ideally, you should use paste, powder, or gel food dyes that are designed for use with frosting. Avoid liquid food dyes since these tend to have a negative effect on frosting consistency. Dunk separate, clean toothpicks into one container of red food coloring and one container of yellow food coloring. Mix both dyes into another sample of white frosting, continuing until no streaks remain. The combination should result in an orange frosting. This second sample may not look exactly the same as your first, of course, since the red and yellow you use may result in a slightly different hue. Create another sample of orange frosting using the orange food dye or the combined red and yellow dyes. Mix a very small dot of black food coloring into the sample, as well. The black should darken the shade of the orange without changing the hue. Only use small amounts of black food coloring at a time, though, since even small amounts can have a dramatic impact on the color of the frosting. If you prepared any additional samples of white icing, you can use them to experiment with different combinations or food colorings. Take notes so you'll be able to duplicate the same orange hues and values later.  Most food coloring manufacturers have recommendations for you to follow, but you can easily experiment on your own. Several ideas include:  Combine nine parts red with ten parts yellow to create a rosy peach color.  Mix two parts orange with one part golden yellow to make an apricot color.  Create a rusty orange by mixing eight parts orange, two parts red, and one part brown.

Align the ring as evenly and as tightly as you can. Avoid holding one end of the right higher or lower than the other to prevent the ring from twisting or tangling as you work on it. Keep the metal ring in-between the two rings. Continue twisting it until the ring is tight between the two rings and you cannot twist the horseshoe any further. Push the two horseshoes together into the middle of the chain until it bends in half. Line up the horseshoes as evenly as possible, allowing the ring to fall to the bottom of the horseshoes. Grab hold of the metal ring and lift it up through 1 side of the horseshoes. If the horseshoes are aligned, the ring should come off without forcing it. Check the horseshoe alignment if your ring appears stuck or you cannot locate an opening at the top of the horseshoes. When you're ready to put the puzzle together again, twist and bend the chain in half to align the horseshoes back together. Drop the ring through one end of the horseshoes, then fold the horseshoes back up and twist 1 horseshoe in the opposite direction to secure the ring.
