Plug still smells after cleaning

I recently purchased a silicone butt plug from Spencers and after using AND cleaning it, it still smells like a bathroom at a football stadium. I've tried cleaning it with warm water and antibacterial handsoap, scorching hot water and dish soap, antibacterial wipes, and a 10% bleach solution. It still smells. I've read online that boiling it or placing it in the dishwasher can get rid of the smell. I don't want to try either of those things because I don't want someone to find it (especially in one of the pots we cook food in). Is it still safe to use despite the smell?
