I have now washed and line dried all the stained linens. I used the Dollar Tree brand of Oxy cleaner because that's what I had in the house. I mixed a bucket full of hot water with 1 scoop of the cleaner and let my fabrics soak for at least 2 days. Then I machine washed them. I put the oxi water from the bucket right into the washer and added detergent. I line dried them in the sun.
95% of the items came out perfectly clean. A couple pieces still have some stains. Now I'll put them all away until I find a use for them. At least they are clean. Thanks for everyone's help and I hope this thread helps someone else too!
