If you don’t have enough time to wash your dirty dishes straightaway, sprinkle them with salt to prevent any food from sticking. Because the salt is absorbent, it will make washing the dishes easier.
To cut grease when washing pans and dishes, add a few tablespoons of vinegar to your soapy dishwater.
If washing the dishes is just not your thing, then you could hire a domestic cleaner to do it for you. There are many London cleaning companies available that can provide domestic cleaning services on a one-off or regular basis.
