I have recently purchased a cleaning solution for precision optics which has the following ingredients (amounts were not specified):
- Ethyl Alcohol
- Diethyl Ether
Typically reagent grade isopropyl alcohol alone is used for cleaning optical elements. So, does the mixture above provide any advantages over using pure isopropyl? (Possible advantages may include a faster dry time, better removal of oils/smudges, and less toxicity)
Any explanations would be greatly appreciated.
