The wear gloves bit.
By the end of the day, unless you are suggesting your riders wear rubberised palm/finger gloves,
(see toolstation page 261 for examples), that could be wiped down between drop-offs with 'antiseptic stuff',
normal/cycling gloves have the possibility of being breeding grounds for who knows what.
Less environmentally aware option is disposable glove over cycling glove for each drop-off.
Hope it goes well for you and your clients.
