You can help keep your wheelie bin clean by being careful about how you throw rubbish away. Firstly, obviously, separate items that can be recycled – cleaning them as appropriate before putting them in recycling bins/boxes. This will also cut the amount of rubbish that goes in your main wheelie bin; this should all be secured properly in a bin liner that can be tied up to avoid spillages inside the bin, and loose items of rubbish and food waste left to rot at the bottom.
If you do notice that a bin liner splits, and liquid or food waste, for example, spills all over the wheelie bin, it’s a good idea to clean it up sooner rather than later – don’t leave it to rot and attract unwanted visitors!
If you take care with the other points, you shouldn’t need to give your wheelie bin a thorough clean too often. If it stinks and you can see there are items of rubbish stuck at the bottom or on the sides, it obviously needs a good clean!
Wheelie bins are quite big, so you’ll need somewhere with enough space to give it a good clean, to allow space for water splashing around, and for easy – and suitable – disposal of dirty water. (If you’re going to be pouring, or letting water drain down an outside drain, make sure it’s suitable/not breaking any local regulations to do so. In some areas, surface drains for instance, might flow into nearby water systems. Main sewer drains, or down the toilet, should be fine.)
Often the dirtiest bit of a wheelie bin is the corners inside at the bottom, where leakages have pooled and debris has got stuck. A suitable broom or mop will help you reach down to clean these areas, and along the sides. A big sponge could be used to clean the outside and around the lid and wheels.
Which products you use may be determined by how much space you have, how you’ll be disposing of the dirty water, and how filthy the bin is. For hardcore cleaning, a product containing bleach or an antibacterial formula (always read the label before use), might be called for. But there is now much greater choice of more environmentally-friendly cleaning products. Plus, if you generally take care of the bin and don’t let it get too vile, plain old soapy water will do the job.
