How to stop a bike smelling like poop?

Hi,

Nope, I’m not joking.

This is the first winter that I’ve kept up my summer mileage, despite the weather. I’m riding at least every other day doing about 100 miles a week. I go out whatever the weather (unless there’s ice about) and I have mudguards.

The trouble is, there’s a pig farm on the way out of the village, when it rains the road is covered by all the pig waste that washes straight out the farm onto the road. The local roads are also covered in cow/pig !”£$%^ and might bike stinks of it.

I wash it every couple rides, but it still smells. Any ideas how to get it smelling better?
