You can use bleach...I think it is 1 part bleach to 10 parts water and rinse VERY well. Someone please correct if Im wrong.
No you're right you can use bleach BUT it must be chlorine bleach not the Lemon bleach for example. Chlorine bleach (common household variety) should just be chlorine and water. You all remember Chlorine it's the stuff they put in our water that we use conditioner to get rid of
You don't have to dilute it but use rubber gloves if you choose to use it straight out of the bottle and wear old clothes that you don't mind throwing out after you're done because no matter how careful you are you will get it on them and they will be ruined.
Rinse well as with anything but Chlorine is destroyed very quickly by sunlight, withing a few minutes, making it perfectly safe for the job but terribly stinky while you're using it... I HATE the smell of chlorine.
You could also use diluted pool chlorine, as long as it doesn't contain a stabilizer, it's the same stuff just stronger but unless you're confident in diluting it properly to make it safe for skin contact just stick with the stuff from the supermarket.
Good luck.
