I have, however, used raw ingredients. Sodium Metabisulphite as a reducer. Distilled vinegar for tea and coffee stains and as a dye fixative. Hydrogen peroxide and ammonia. Choose the right source and brands and you can easily download the safety data sheets so that you don't have problems with the authorities. Didn't have one for the vinegar though. I kept that in my van to add to my fries at lunchtime
