The Aussie Bulldog
I hit mine with the Australian version of Scrubbing Bubbles, then wash it in hot water and dishwashing detergent. It may take a few washes depending on how dirty it is. I then give mine a small soak in diluted Dettol which is a disinfectant. Then they are right to go. Everyone has their own idea. Just try a few and see what works for you.
