Before You Start

Identify the stain type and fabric or fiber. Test any cleaner on a hidden area to check colorfastness and avoid damage. For delicate fabrics, consider professional cleaning for set-in stains. Allow time for the stain to air-dry between steps and avoid heat until the stain is fully lifted, as heat can set oil further. Critical cautions: never rub vigorously, use hot water on protein-based fibers, and never mix cleaners with bleach.

Step-By-Step: How To Remove Set-In Oil Stains

Scrape off any excess oil with a dull edge, taking care not to push the stain deeper into the fabric.
Blot the stain with a clean cloth to absorb surface oil, then apply the oil stain remover spray for fabrics enzyme cleaner to the affected area.
Let the cleaner sit for 5–10 minutes to break down the oil, then gently agitate with a soft-bristle brush.
Rinse or blot with warm water, repeating as needed until the stain lightens noticeably.
For set-in stains on fabrics, apply a pre-wash laundry stain remover for set-in oil stains and work into the fibers with the brush.
Wash the garment as directed on the care label with the longest cycle available for the fabric, using the appropriate detergent.
For carpet or upholstery, spray the carpet upholstery stain remover with brush applicator oil stain cleaner over the stain and blot from the outside inward to prevent spreading.
Repeat treatments if necessary, but avoid over-wetting. Allow the area to air-dry away from direct heat.
Check the treated area after drying. If any trace remains, repeat the steps above or consider a professional cleaning for stubborn spots.
Once the stain is gone, protect the fabric by applying a stain guard if appropriate for the material.
Document maintenance steps for future spills, especially on high-traffic fabrics and carpets.
