It doesn't look like there is anything harmful/toxic in them but I would use something that sanitizes as well. I suggest a combination of spot cleaning with a vinegar/water mixture which helps get the solid bits up. Then spray it with a disinfectant like F10SC or using a small steam cleaner. Otherwise you could use the wipes to get the solid bits, wipe it with some water to rinse it, then disinfect the area.
I don't like to use those because they may leave a harmful residue if not rinsed thoroughly. I prefer F10SC for a disinfectant because it's safer when diluted to spec.
