Yes , I think the mixture is 3 parts water and 1 Part bleach. I know this works for mold on hvac grills.
Absolutely not! Any bleach having been diluted or not could result in a very unpleasant experience for you. Keep in mind what the word bleach actually Means because that is what it can and will do to the finish on your cabinets. Depending on how diluted the bleach actually was, it could even take the finish completely off your cabinet's.
