The services of commercial cleaners are most likely to be needed in Cardiff, a new survey suggests.
According to research from Keep Wales Tidy, Cardiff and Blaenau Gwent have the dirtiest and most littered streets in the country.
A 12-month long survey found that the streets of Blaenau Gwent are littered with discarded food wrappers, drink waste and dog foul, while Conwy was found to be the cleanest area.
Some 3,464 roads were inspected as part of the extensive survey, which revealed that overall, there has been a drop in the amount of litter in Wales and the overall cleanliness index in the area has improved.
Blaenau Gwent and Cardiff councils said they are working to improve the levels of cleanliness in their areas.
Representatives from the councils said they will be employing extra cleaning machines including a new cigarette cleaning vacuum to deal with the litter problem.
A member of staff will also be tasked with emptying and cleaning dog bins in the county every week.
Commercial cleaners from London cleaning companies can be hired to improve the overall level of cleanliness in your area.
