As I said before BE CAREFUL. Washing with a pressure washer is NOT being careful. You will blow holes in the fabric and destroy the resin that is in the fabric to keep it crisp and tightly woven. Holes in the fabric will reduce the pressure differential across the sail surface and it will result in a "blown out" sail. Remember; the sail needs to be air-tight; and blasting water through it will surely damage/destroy this.
Also; try not to use too much oxalic; remember it is an ACID. Use it sparingly; and if the stain won't come out; just live with it. The stain is doing less damage to the sail cloth than the cleaner.
