Experiment 1- Temperature of detergent medium at start
A warm medium, with temperature of around 50 degree celsius is the most ideal temperature for effective stain removal.
Using the recommended concentration or slightly above the recommended concentration of detergent would be the ideal detergent concentration for effective stain removal. But the saturation of stain left for the recommended concentration and slightly above the recommended concentration do not differ much, at only 1.8%. When too little/too much detergent is used, stains will be less effectively removed.
A neutral pH is most ideal for the effective removal of stains.
