Sorry for the late reply but I do bin cleaning I don't use any chemicals, just use a really good pressure washer. Anything at Honda 160 -200 is enough. I cant even run that on full power without moving the bins with it. Make sure you recycle the water as it powers through it. Then spray it with a strong disinfectant that has a strong smell, I use lemon diluted to about 50/50.
That will get rid of any muck.... second cleans are always easier.
