I carry out holiday change overs for s complex of holiday flats( about4-5). They have asked me to clean their wheelie bins once a month and asked how much would I change?. I have entered a search on here to make the questionhas not aalready been asked snd came up with environmental issue. These are household size bins and I was going to use some household disinfectant. ?. Can anybody give me some advice regarding the procedure and price? Thank you in advance . The flats are up a hill down quite a few steps from the flats ..is the bins are kept very close to the road .
