I'm pretty new to this Quilting Board and I'm sure that this question has been addressed numerous times but I don't have time to go thru all 915 pages. Is there any way to get the musty smell out of the older Singer machines. I have a 221 and just purchased a 301A that I love and am using for my quilting. The 301 is not in the case because I'm sewing with it and I have to purchase a new case for the 221. I'm still holding on to the original cases. But the smell gets to my asthma. Any good suggestions would be appreciated and I'm thanking all in advance. Blessings, Nancy
