Question about Sanytol Laundry disinfector

The product is used in the washing machine by adding 45 ml of the disinfectant to the rinse compartment instead of the fabric softener. You can set the washing programme as usual. For hand washing, mix 20 ml (1/2 lid) with 3.5 litres of water in the final rinse water and leave to work for 15 minutes before rinsing thoroughly.
