Advice - stained old linens
In cleaning out my Mom's belongings I found a box with old pillowcases and old store bought aprons. Some of the aprons had paper store price tags attached with straight pins. Based on the location of the store, I think these items may have been given to my Mom by my grandmother who died in the early 1960's.
Some of the pillowcases are badly stained with age related dots. They feel brand new and unwashed. I think it's possible my grandmother made them with "pillowcase fabric", the kind with the edge printed on it. Some of the brand new (with tags) aprons also have stains, brownish yellowish ones. Some are unscathed.
I've washed the pillowcases and one of the aprons. The stains did not come out. I am line drying them.
I have no immediate need for any of this so I'm tempted to just put them in my attic for another day. Will this cause the stains to set any further? I'd rather not go to great lengths to clean them right now. I'd rather wait until I need to use them, if I ever do...
Thanks.
