I only use on the kitchen counters and stainless sinks -- then I rinse with water. ...hmmm... guess, I should go back to the 50/50 solution.
Typical chlorox disinfectant mix is around 16 :1 (a cup in a gallon of water...)
3 fingers in a spray bottle is around 8:1 and is used as I said to bleach out stains in wood... That is fairly caustic.
Do what you do, your business and all, but I don't think you are getting any more value as a disinfectant with such a hot mix. And even 8:1 (plenty hot) would be easier on your lungs and skin.
