Question

it's quite old

Answer 1

You can try using some Dawn (non-bleach kind) dish soap and warm water. Use a scrub brush or get the majority of the gunk off of it. The if you haev an old toothbrush, use it to get into the smaller detailed areas. Just be sure to rinse all of the soap off after you are finised. You can go ahead and use a towel to dry it. Or just let it air day on its own.
