OT8 is a good product, but if you want to double hit the stain, then Resiblock OR first before you start washing, allow dwell time etc, then wash off, then follow up with OT8 as this can go on damp/wet surface's where as the OR needs to go on a dry surface.
The OR for those that might remember it, is the closest to Tech-cleans degreaser which was the best around.
