countertop disinfectant

Bleach is a good way to keep bacteria off of the kitchen counters and sinks.  You don't need much.  I keep a quart sized spray bottle with 2 tsp bleach and the rest water.  That's all you need.  It's enough to kill germs but not enough to ruin your towel or washcloth. 

Additional Notes:
It's also good for cleaning bathrooms counters and sinks.
I also use this same mixture if my puppies goes to the bathroom on the floor.
