Accidentally used silicone lube on toy - Help Please

I got my first Monster Toy recently. A Tentacle Knot toy, size small, extra soft from Uncover Creations.

I was really excited to try it out but I didn't pay attention when grabbing the the lube, so I ended up using my silicone lube instead of the water based, only realizing too late.

Needless to say, now my toy is really sticky and I can't seem to wash it off. I've tried warm water and gentle, unscented soap and even hot (not boiling) water. But nothing seems to help so far.

I really don't want my first toy to desintegrate or be unusable. I appreciate any advice I can get. Thank you.
