The moment of dread. You enter a public-slash-private locale (hotel room, library commode, the neighbor-with-triplets’ kitchen) and panic sets in. You can’t avoid it: bacteria.

Whipping out the hand sanitizer, you wildly rub it in as fears of E. coli and foot fungi swirl. You will lose this battle.

Unless, that is, you’ve packed your SilverClene 24, a four-ounce spray that’s powerful enough to be your very own purse-sized WMD. (It also comes in larger sizes for in-home use.) Aim the nontoxic, odor-free, silver-based sanitizer at any surface and — bam! — within 30 seconds every last microbe is destroyed. (It’s true: It’s science.)

Salmonella? Flu? Zapped. Hospitals use it. Equestrians use it. Even your grandparents used to. (Silver was the first antigerm agent.) Spritz counters, doorknobs, even the john. SilverClene 24 keeps nasty buggers away for at least 24 hours.

Though, unfortunately, it’s powerless against the neighbor’s triplets.
