How to Dispose of Linseed Oil

Linseed oil is made from the pressings of the dried, ripe seeds of the flax plant that are then exposed to a solvent extraction process. In its untreated form, it's used as a nutritional supplement that is said to ease constipation and lower cholesterol. You can dispose of it by any responsible means in this form. Boiled linseed oil is a woodwork finish and an art material and can be dangerous if disposed of incorrectly.

Instructions

  1. Excess Oil

    • 1

      Put any excess boiled linseed oil that you want to dispose of to one side. Do not pour it down a sink or drain. Linseed oil cures hard and may block drains as a consequence. Do not cover the oil and make sure it is in a well-ventilated area where it will dry quickly.

    • 2

      Allow the linseed oil to cure for 24 hours or until it has hardened.

    • 3

      Throw the cured oil away with your general trash.

    Soaked Rags

    • 4

      Place any boiled linseed soaked rags in the metal container. Linseed oil dries through a process of oxidation that produces heat. This could cause the rags to spontaneously ignite.

    • 5

      Seal the metal container until you're ready to dispose of the rags.

    • 6

      Incinerate the rags.
