Basically the ingredients to make homemade Febreeze are a mix of water and fabric softener.

Directions:

• Unless otherwise noted, place ingredients in a spray bottle and shake well to mix. Test a small unnoticeable area first before using to make sure no discoloration or damage occurs. Use as needed, shaking well each time before use.
