White coloured Oil Only absorbents are hydrophobic. They absorb just oil-based fluids but repel water-based fluids. For locations outside, in or on large bodies of fresh or saltwater subjected to weather exposure, Oil only absorbents are particularly suited, as they will only recover oil-based fluids without soaking up any water. In most instances white Oil only absorbents will be best suited to the vast majority of tasks involved in oil and gas refining, transportation and distribution. For vehicle fleet management, fuelling and servicing, Oil Only absorbents will provide the better option here too. For more generic building maintenance and cleaning grey Maintenance absorbents will cover the tasks at hand. For any aggressive spills like acids or alkalis yellow Chemical absorbents should be the default choice
