Snakes and rubber, not rubber snakes

[rover95disco]

Recently picked up a new hide box for our mexican pine and the hide has a very strong natural rubber smell. I have washed it repeatedly and even buried it in kitty litter for four days(read that on a forum about dog training aids) and the smell is still there, it's like what new floormats or gym mats smell like. I haven't put it in her enclosure for fear of it putting her off or making her uncomfortable, is this something I should be concerned with?
