Bought this massive gator skull from a lady about a month ago, been cleaning it since, soaked it in Hydrogen peroxide, took it out, started stinking, tried dish soap to see if there was any degreasing or anything left in it, didn’t help, then soaked it in hydrogen peroxide again and took it out today. Still stinks in certain spots. What do I do! I’m fairly new to cleaning bones so I expect I’ve done something wrong, but I don’t want to keep spending chunks of cash on peroxide. Please help.
