Thanks for the response.

I have been soaking it down with water a little bit of vinegar off and on for the best few days. Hopefully after a few more days of it and few good rinses it'll be ready to use. Unfortunately parts of it started cracking but hopefully it'll hold up.

We pulled the sac about 2 weeks ago and have been incubating the eggs but its looking they are duds sadly. We will just have to find her a boyfriend this summer and try to get fertilized eggs. Currently we have 3 tarantulas expecting to lay a sac and we mated them so the eggs will / should be good.
