Google is honoring Danish chemist S.P.L. Sørensen today with another one of their interactive doodles. Sørensen’s claim to fame is his introduction of the pH scale, which he developed while studying beer. The scale measures acidity and alkalinity, and while you may not think it has any use to you outside of a high school chemistry class or in your job as a non-chemist, you may be surprised to learn that a passing knowledge of the pH scale can be very useful.
Glasses and sunglasses wearers alike spend a significant amount of time cleaning smudges and dirt off their lenses, but not everyone knows how to clean their lenses properly, and safely. A cleaning solution that is too acidic and abrasive can cause irreparable damage, and fixing ruined lenses can mean an unnecessary expenditure of a few hundred dollars.
However, there is something in your house that is safe to use which you may have never considered before…
Common, household dish soap is an excellent cleaning solution for getting the gunk and grime off your glasses or sunglasses, and thanks to S.P.L. Sørensen, we know why:
“The pH of dish soap is slightly alkaline. The alkaline medium helps in alkaline hydrolysis of the esters inside the soap. This process breaks the ester into a carboxylic acid and alcohol. Because of the alkaline medium, you get a carboxylate ion and alkoxide ion.
Molecules form ion-dipole interactions with water, allowing them to be dissolved. The long carbon chains form id-id interactions with the organic molecules such as grease, oil, etc. The greasy oil bonds to the long carbon chains of the ions, the ions get dissolved into the water, and everything gets washed down.”
Long story short: bad stuff goes, good stuff stays. While not all dish soaps are made equal, many basic bottles should be perfectly safe. Always check labels, and Google searches cost nothing. Or, best option, just stop by Blink Optical for a free bottle of cleaning solution and a lens wipe. Always free, purchase or no purchase (in-store only).
Blink Optical, always with you in mind.
