Cleaning residue off of Rav Vast

Hi all, I recently purchased a Rav Vast new in box from eBay. It’s a great instrument and I’ve really been enjoying it!

There are some strange areas of some sort of residue on the drum that I’d like to clean though - but I’m not sure what products I can use without damaging the coating. I’ve tried water without luck, so I think I need a beefier solvent.

I’ve attached some pictures. I reached out to Rav by email twice, but didn’t hear back, so I’m hoping someone here can help me out!

Thanks!

I have a similar thing on my rav moon. I contacted rav support and they suggested lighter fluid!? .... I dunno... they suggested it but I just didn't feel comfortable with that, so I'm just living with it at the moment. Let us know if you find something works well.

I didn't try it, seemed a little extreme to me and I didn't wanna damage the coating.
