@melbaboutown @briongloid my maximum attack cycle (assuming you get the offending item fresh!) is presoak in a bucket of Sard soaking solution with the full quota recommended in the hottest water available for several hours. Then (front load machine) put another generous portion of Sard in the prewash dispenser and max half recommended detergent on a hot cycle (60+). Increase water level and rinse cycle as machine allows. Good luck!
@melbaboutown @AWStephen Sard Power Soaker. Bear in mind that Aldi now has very good equivalent products at sometimes significantly reduced cost. I just don’t have 25yrs experience with it like Sard.
