After shaking, you should turn the pump head briefly to the left and hold it by the lower part, as otherwise it could come loose due to the resulting pressure. Pour the washing-up liquid directly onto the sponge or dishcloth. There will be no excessive foaming. However, efficient cleaning does not require a great deal of foaming either.
To save water and energy and still clean efficiently, soak the dishes instead of washing them under a running tap.
Please clean the bottle thoroughly before refilling.
