I've had people look at me funny when I wipe the the cart, but I don't care. My grandson has caught two nasty bugs off those things, once because I had cleaned out my van and forgot to put the wipes back in . I have two containers of wipes I keep at all times. If I'm in the store and I see someone with a small child and he/she has their mouth on the handle, I will tell the parent about what happened to my granson. I know that's where he caught it because that's the only places I ever went. He caught something one time and passed it through four of us and I can tell you it's not something I want to ever get again. So, anyone with small children, PLEASE wipe the carts down really well.
