For bleach go to chemical place like univar or clear tech you can buy calcium hypochlorite powdered bleach.
You can also buy at pool places just MAKE SURE ONLY CALCIUM HYPOCHLORITE some comes with algaecide which you don’t want.

Disinfection with Calcium Hypochlorite
Don’t make pails of liquid bleach it just mix as needed as it decays fast in sunlight. I just use direct into our bleach bowl on counter it holds 4 L or about a gallon of water use a plastic fast food spoon we use the equivalent of a Wendy’s spoon half full for the solution
Keep it for max 2 days and then toss.
When you come in from farm work gloves or not you wash hands then disinfect before you start kitchen work and every time you change what you are doing. We bleach all utensils and have a water disinfect at 69c at each knife station just like at our meat processing building.
We also black light check our home once a week to make sure no buildup. Yeah I know germa phobe but we have elderly with weakened immune systems… I drink from creek water no treatment.
