Sport wash from Amazon. If everything you did hast hurt I doubt this stuff would.

It's probably oil base , you might try to soak it in dawn soap. Rinse before washer.

If you don't have anything big enough to soak you can try sport wash from Amazon, link below. Vinegar in the rinse would help also.
