What is the best way to get odours out of old books? Today is moving day. 


For the past few months We've been living on a family members couch due to the roof in our home being filled with mould that was making us sick. 


Today we get a new apartment and have to go back to the house to grab some things. Due to the mould we can't bring everything but I have a very large collection of books that have been kept in a different room than where we found the mould issue. For obvious reasons I don't want to leave them behind... 


Is there a way to deodorize and clean the books without ruining them? 


In the past I've used scented dryer sheets to refresh old books i've gotten from yard sales or used book stores but that is more just masking the smell rather than cleaning them and with as many books as I have, it'll take a lot of dryer sheets (10 per book at least). 


Are there any better ways or is it a lost cause? 

Any help is much appreciated! Thanks!
