Cleaning joggers

You can but they still don't come out very clean, they need to be scrubbed first. Soak in a bucket of warm (not hot or it can weaken glue) with washing soda for about half an hour. Make a paste with washing soda and scrub the bits that are still grubby with an old scrubbing brush like around cut material, sewing lines, rubber, shoe lace holes. Chuck in the washing machine and wash like normal in cold water. For really greasy shoes spray with degreaser before soaking.
