I make up a solution of 1 part bleach to 5 parts water. Since I want enough to cover whatever size clay pots I want to clean/disinfect, I might make up 2-4 gal. of the solution in a bucket. If its 3 gal., that would be 2 qts. bleach and 10 qts. water. I use hot water. I just put the pots in the bucket and pour the solution over them, enough solution to cover the pots. I let them soak for 30 minutes but longer won't hurt a thing. Then I take them out, and while they are still wet with the bleach solution, I scub them with a 3M scrub pad, those green pads found in grocery stores. Then I will rinse them off and put them somewhere to dry.
Be careful with the bleach solution. You might want to wear water-proof gloves and don't get the solution on your clothing.
