We recently moved my 90 year old uncle out of his home where he has lived since the 1930s. Needless to say we found a lot of "treasures" and "keepsakes". He & my mom, 6 other siblings, their parents, and a grandpa lived in this one bdrm 1300 sf home. The still unfinished basement used to house many beds! Over the years it became the storage unit for many of the siblings. One thing I snatched up was a wool cap warn by my grandpa or great grandpa maybe. I would like to know the best way to clean it. It is in excellent shape, albeit the smell and grime on it. Also, what is the best way to clean the old lace, collars for dresses, crocheted purse, etc?
