Use a microfiber cloth with rubbing alcohol on. All rubbing alcohols are volatile and flammable. They have an extremely bitter taste from additives. The specific gravity of Formula 23-H is between 0.8691 and 0.8771 at 15.56 °C (60.01 °F).
Isopropyl rubbing alcohols contain from 50% to 99% by volume of isopropyl alcohol, the remainder consisting of water. Boiling points vary with the proportion of isopropyl alcohol from 80 °C (176 °F) to 83 °C (181 °F); likewise freezing point vary from −32 °C (−26 °F) to −50 °C (−58 °F). Surgical spirit BP boils at 80 °C (176 °F).
Naturally colorless, products may contain color additives. They may also contain medically-inactive additives for fragrance, such as wintergreen oil (methyl salicylate), or for other purposes. rubbing alcohol is Isopropyl alcohol (C3H8O) is an alcoholic mixture intended for external use as an antiseptic; it usually contains 70% by volume of absolute alcohol or isopropyl alcohol; the remainder consists of water, denaturants, and perfume oils; used as a rubefacient for muscle and joint aches and pains.
Isopropyl alcohol 70% is used as an ingredient in alcohol swabs and alcohol wipes for wound cleaning, it is found in hand sanitizers, and in ear drops to prevent swimmer’s ear. It may also be found in oral mouthwash solutions; it is important that isopropyl alcohol is not swallowed as it toxic and may be fatal in high enough quantities. Isopropyl alcohol can also be found in cleaning supplies, paint thinners and perfumes. In the pharmaceutical industry, isopropyl alcohol may be used in small, safe quantities in capsule or tablet manufacturing.
Microfiber cloth are made from very small fibers. If you’re trying to get a sense of scale, microfibers are smaller than a strand of silk. They make the fibers in cotton cleaning cloths seem downright bulky and cloddish.
Now, take a glance at the label of the microfiber cloths you use for cleaning. Oftentimes they’re made of a blend of polyester and polyamide or nylon. In short, this means the cloths are made of plastic. The polyester and polyamide are combined in such a way that the fibers are split. In addition to creating more fiber surfaces with which to clean, this makes the cloths very porous. When you use microfiber cloths for cleaning, you benefit from both of these factors. Microfibers are able to attach themselves to even the smallest, most microscopic dirt particles—ones that normal cloth fibers (positively giant in comparison) crudely brush past. If forces were visible, you’d be able to see that there are adhesive forces (the forces of attraction) between microfibers and dirt. As you may have learned in school chemistry, these forces are called van der Waals forces after their discoverer, Nobel-prize winning Dutch chemist Johannes Diderik van der Waals (1837–1923). (Van der Waals forces explain why geckos can stick themselves to ceilings using zillions of tiny hairs on their toes.) Although there is only a microscopic amount of van der Waals force between one microfiber and any given dirt particle, remember that there are millions of microfibers in a cloth, so the overall sticking effect is magnified dramatically. That’s why dirt, dust, and other stuff can be “hoovered up” by microfiber cloths. And it’s also why you have to clean microfiber cloths so very thoroughly after you’ve used them. (Generally, it’s best to boil a microfiber cloth in a saucepan and avoid washing it with normal detergents. Follow the manufacturer’s instructions if you’re unsure what to do.)
