Does anyone else get worried by this?

I have recently started washing my hands at least once an hour and everytime before I touch food etc. However this then leads to another worry than soap particles on my hand. will transfer on to the food I eat such as when washing my hands with soap and then eating a sandwich etc.

I also hate to come in contact with household cleaning chemicals etc. the other day being a bit apprehensive about stepping into the shower because my mother had cleaned it with chemicals earlier on in the day....
