WHOA so back to stuff like washing bedding etc. LONG thought of the whole aspect of all that, more than you could possibly care to know. Reeling in info. I was like GOTTA be a more natural way. Washing my bedding, and decided to also add pure almond extract. FOOK their poison scent extenders, I'll let ya know how it turns out then could OBVIOUSLY use any natural scent. No I have not looked it up, yes I think SURELY a simple inquiry at this point would gather info.
