My idea is for a shopping cart wipe. As a professional nurse, I know just how dirty and gross public items can get over time. Shopping carts are the worst. Fecal bacteria to TB are all over shopping carts. Having a small pop-up like those used for baby travel wipes specifically formulated for nasty things on shopping carts are needed. The dispensers already exist. The refills would a profit maker and even the initial dispenser will not need to be developed. The exact formula for the chemical in the wipes will need attention. Money will need to go toward public education. The formula for the wipe should evaporate quickly so that if Clorox is used, the wipe will not cause staining or bleaching of clothing.
