Check out Thieves household cleaner. It seems very expensive–but it is highly concentrated, so it really last’s forever. It is WONDERFUL stuff. It is 100% natural–you could drink it if you wanted to. It will kill your mold totally–which actually bleach does not. There have been many studies done on it, it is actually used for cleaning up black mold, and it does a better job than bleach. If you want more info. about it you can google it, or e-mail me off list.
