POS terminals need sanitizing, too

For servers already loaded with side work, cleaning a touchscreen is just one more task on a lengthy list, said Thomas Kapfhammer, general manager at Rocky's Italian Grill in Jeffersonville, Ind. But with servers' hands moving from dirty plates and glassware to money, to doors and to the POS terminal, it's a necessary step.

"Everything, I tell them, gets sanitized, right down to the POS," Kapfhammer said. "Too bad if they don't like it. They have to get used to it because it all needs cleaning."

No doubt the task is easier when touchscreens are used, versus standard keyboards, especially those without transparent, disposable dust covers. But even though touchscreens are easier, they're sensitive to sanitizing chemicals, Kapfhammer said.

"We always stress that they use a cloth that's not too damp, because any more liquid than that could fry the machine," he said. "And that turns out to be a very expensive sanitizing."

POS manufacturers agreed, saying treatment is all that's needed, not washing. One recommended using an ammonia-free glass cleaner for touchscreens, but stressed that cleaner should be sprayed onto a cloth and never directly onto the screen.

"If it's a non-sealed unit, the liquid could seep into the unit and cause damage," the manufacturer warned.

Another manufacturer said to make sure to turn the power off before sanitizing a POS unit to avoid damage or electrocution. And since that's not possible during service hours, she stressed that servers regularly wash their hands to reduce chances for contamination through the keyboard. Amid service, a quick wipe with a damp cloth can help, she said.

Both manufacturers said keyboards can become safety hazards or suffer damage if not well-maintained. Removable transparent covers are strongly recommended, especially in food preparation areas, both for sanitation and to improve the life of the keyboard.

When soiled, one said treat them as if you were cleaning any ordinary keyboard. Turn off the POS unit's power, shake any debris from the keys or clean with compressed air, and then wipe the entire piece with a cloth lightly dampened with a sanitary solution.

"If you're preparing any food at all and using a keyboard, it's probably best to wear gloves, too," the manufacturer said.
