Stain Removal
How to remove oil stains
Oil stains can look faint when wet and then darken after drying. Treat them as residue stains: give detergent time to surround the oil, avoid dryer heat, and inspect in bright light before deciding the stain is gone.
Quick answer
Blot excess oil, apply liquid laundry detergent or a label-safe grease-fighting pretreatment, let it sit briefly, wash by the care label, and air dry before checking for a dark shadow.
Never mix bleach with ammonia, vinegar, rust remover, or other cleaners. Test a hidden seam first. Use professional cleaning for valuable, delicate, wool, silk, leather, or dry-clean-only items.
Stain-specific decision points
First action: Blot fresh oil with a clean cloth or paper towel without rubbing it wider.
Heat warning: Do not put oil-stained fabric in the dryer until the shadow is fully gone.
Fabric limit: Denim and cotton often hide oil until the fabric dries, so inspect before drying with heat.

Fabric notes
FAQ
Why is oil still visible after washing?
Oil can remain as a translucent shadow after water evaporates. Repeat detergent pretreatment before using dryer heat.
Should I use hot water?
Use the warmest water allowed by the care label after detergent pretreatment. Do not override the label for delicate fabrics.
Can dish soap be used on clothes?
Some people use a tiny amount for grease, but laundry detergent is safer for machines. Too much dish soap can create excess suds and residue.
