Great detergent, gleans well and leaves a nice scent. Like pretty much every manufacturer, Henkel provides a cap that is about three times larger than the recommended dosage. The instruction says "fill cap to level 1", but try to see that marker in the cap. After rinsing the cap and holding it against sunlight, I detect levels A,B,C,D,E, and Level 0, 1, 2. Your only chance of correct dosage is to take a permanent marker and emphasise this level, which turns out to be about 1/3 of the cap. Do your wallet, your health, and our environment a favour and do not overdose - 1/3 of the cap is all that is needed for a regular loa.
