Goggle Sanitizing
You may be lucky enough to afford an ultraviolet sanitizing cabinet. If not, Lysol®
kills gram positive and negative bacteria, including pseudomonas, staphylococcus,
streptococcus, lipophillic viruses like the influenza virus A-2, herpes
simplex, vaccinia and adeno type 2. Lysol is a concentrate. Dilute the Lysol in a
full bucket of deionized water, immerse the goggles, and allow them to air dry.
