How do you removes stains from vintage linens?

I use oxyclean.I make a paste with it and brush it on the stained areas.I soak the linens for two hours,adding extra oxyclean in the machine.Use the hottest water for the fabric,let the machine agitate for a couple of minutes to work the oxy through the fabric.After that,let the machine finish the cycle, then use regular detergent, and run the cycle again.
