It leaves a residue if you try to use it as a cleaner. It certainly will affect its action as a solvent. Further, it is "spiked" (denatured) with methyl (wood) alcohol to act as a disincentive to human consumption. (Our government doesn't care if the wood alcohol blinds or kills you while you try to avoid the taxed ethyl alcohol!) If you want to avoid the methyl alcohol and oil, ask the pharmacy for USP Injectable alcohol (but I don't know what the standard concentration is). -------------------------- Ed Price [email protected] Electromagnetic Compatibility Lab Cubic Defense Systems San Diego, CA.
