First, add 225 ml of warm water (about 35–40°C) to a bottle. Then, add one packet of dishwashing powder (25g), close the bottle tightly, and shake it vigorously for about 10 seconds.
The powder will begin to dissolve after a short time – usually within 5–10 minutes.
If some particles are still visible, that’s completely normal – they usually dissolve gradually.
You can already use your dishwashing liquid. By the next morning at the latest, the mixture should be fully dissolved and turned into a gel-like dishwashing liquid.
