I wash out my 4 litter trays in the bath; its the only the only thing that will hold all the trays and scoops etc
(3 of them are jumbo littertrays!) using hot water and a scrub brush.
They're then left to drain and sprayed liberally with 'clean and safe' disinfectant from PAH. It kills all viruses including Coronavirus.
Then they get dried off with old towels......the towel goes straight in the wash afterwards.
All great fun
