Customers today have been looking to save money anywhere they can, so Spilltech answered back. If you need the best priced oil absorbent, look no further. Don't worry, these are a US made quality oil only pad. Cost were saved by not finishing them the same way as some of the other premium oil pads and are just a little smaller at 15" x 18". They are constructed of a meltblown polyproplene and finished with dimpled bonding points and a perforation. If you have leaks or spills, these are perfect for you boat or shop. They may lint a little if used as a wiper.
Have you heard of the term oil diaper? Ships engineers lay them in the bilge to remove oil and they got nicknamed Oil Diapers. So they are a oil diaper for your engine, makes perfect sense when you think about it.
