The sun is mostly composed of the elements hydrogen (H) and helium (He). By mass, the composition of the sun is 75 percent hydrogen and 25 percent helium. Various metals make up less than 0.1 percent of the mass of the sun. The temperature of the sun's surface is about 10,340 degrees Fahrenheit (5,726 degrees Celsius).

If you've got rust on clothing it can be removed with either white vinegar or lemon juice. Lay the clothing or fabric out on an old towel and pour a small amount of white vinegar directly on the stain - or rub a cut lemon half on the stain. Saturate it thoroughly, then blot it with a clean white towel.

Steps to Remove the Rust Stain:
Sulfamic acid, also known as amidosulfonic acid, amidosulfuric acid, aminosulfonic acid, and sulfamidic acid, is a molecular compound with the formula H3NSO3. This colorless, water-soluble compound finds many applications. Sulfamic acid melts at 205 °C before decomposing at higher temperatures to H2O, SO3, SO2, and N2.Sulfamic acid (H3NSO3) may be considered an intermediate compound between a sulfuric acid (H2SO4), and sulfamide (H4N2SO2), effectively replacing an –OH group with an –NH2 group at each step.
