They have a lemon/lime roll of 40 pull-out wipes in a tube that fits quite well in most drink holders. I pull one out just as I leave my car when going to the supermarket to wipe the handle on the shopping cart... Even though most supermarkets have them by their doors, I usually pick a wagon that someone left in a parking space.

Salt and pepper shakers are another filthy thing, but paper money is the worse.... you don't know who's dollar bills you're getting in change or if they even washed their hands after using the restroom.

Thanks for mentioning Walmart's product; I'll certainly give it a try...
