The main active ingredients in our tabs are food-grade citric acid, soda and oxygen bleach. This natural combination works very well for everyday soiling, but is no match for the classic chemical bomb. However, many people don't realise this: Extremely strong cleaners may clean superficially faster - but they leave a lot of environmentally harmful residues in the waste water. In most cases, the gentle detergent tabs are sufficient - you should only use our power powders for heavier soiling.
