I prefer hand wipes over sanitizer.
Also, please don't wash gear directly in a river or lake. Carry the water a distance away, wash, and then dispose of it away from the river/lake.
If you're by yourself, or with others who maintain good hygiene, then simple soap is fine. As someone mentioned, gear used with bateria-unfriendly foods - such as dry foods or watery fruits - can simply be wiped. Gear used with eggs or meat should be washed w/ soap. Boiling will kill nasties.
Don't be confused with the fact that we don't soap wash cast iron. Those pots have been heated enough to kill most bacteria - eating and food prep gear have not. Big difference.
Though it may seem extreme, if you're with a group, then you want to add a sanitizing step using a 100 PPM bleach solution (1 tablespoon/gallon) for at least 1 minute, quaternary solution, or boiling water. In groups its all too common for folks not to clean hands after deficating. Those contaminated hands then reach into rinse water and theb contaminate other campers' eating gear. It happens.
