Great save product
Lost my oil filter cap, engine covered in oil I thought car would be badly damaged and costly. Used this amazing spray then took to garage and it had cleared and cleaned everything off, so no costly repairs. Would recommend

Engine Oil Spill; block paving - use it, you won't regret it.
OK, this is not about Gunk's engine cleaning capability. I used Gunk to clear a 4 day old engine oil spill on my block paving. The patch was not old oil but it permeated the block paving over a couple to 3 days before I could clear it up. I sprayed on the gunk to the area affected (approximately 5-10 sq ft. I gently rubbed the mixture into the stone and left it for 20 minutes, afterwhich I used a hose to clear it away. After about an hour , when it had dried it was as though the oil stain never existed. Remarkable.

Good strong degreaser….that works.
Course, it works best if you agitate it with a paint brush or other agitatey thingy.
