Just interested to see how yours is done.
I:-
Empty it all into a black bin back and scrape out any clumps sticking to the bottom
Put a squidge of bleach into the pan and pour in freshly boiled kettle water.
Let it soak for a moment and then rinse out with more kettle water.
Dry it all off with a towel which then goes straight into the washing machine.
Pop in new litter, add the hood and voila, done.
sweep around where the litter box is due to the cat throwing it out
