Review on PNR16OZ-08 Edgewater Industries 16 oz Oil Stain Remover by Justin Falker

Slightly disappointed in its performance. Suitable for light spots, but not for dark spots where the car has been dripping oil for a long time. The instructions state that if the stain is severe, a touch-up treatment may be required. However, given the low coverage I got from the first bottle, I decided to try something else. So instead of a second coat I used 100% TSP and a spatula. It worked. On some other stains that I haven't used with Pour-n-Restore (due to limited coverage), I used TSP first. It worked well on light spots, but again only on very dark spots. I then tried WD-40 on these stains. The combination of TSP and WD-40 worked pretty well, especially after I washed off the WD-40 residue with soap and water. I think it would be more effective to use WD-40 first.
