Bilge Oil absorbent. Absorbs up to 3 litres of oil or Diesel. Manufactured from meltblown polypropylene and specially treated, Cleana Marina Bilgeels will quickly absorb large spills of oil or diesel. It's sometimes very difficult to get complete access to the bilge. You know the oil is there, you can smell it but you just can't get to it. Bilgeels are designed to be stuffed, pushed, wriggled, floated or lowered into oil filled areas. Their absorbent body just loves oil yet the absorbent core hates water but also loves oil, so they float. Perfect for hard to reach bilges!
