Robert, now that you mentioned it...
We all know it's hard to find vintage laundry detergents (both liquid or powder) and I'm 99.9999% sure you use vintage only for special ocasions, and a modern detergent for the daily duties.
If appliable, which brand(s) and version(s) of modern detergent(s) you use? What other aditives? (Softener, bleach, oxy bleach, stain remover, dryer sheets, iron aid spray, etc)
