Oil-Stain Care for Cotton Clothing
An oily patch needs more than a decision to wash the garment again. Remove excess without spreading it, check the cotton item's full care instructions, and choose a compatible pretreatment. The type of oil and the presence of other fibers or finishes still matter. Inspect the result before adding heat that could make remaining residue harder to remove.
Cover the stained area first
Ariel's method for butter, cooking oil, and grease begins with applying liquid laundry detergent directly to the mark. The treated garment then goes into a compatible wash load without the pretreatment being rinsed away first. Use the amount and procedure specified for the actual detergent rather than transferring a dose from another product.
Wash within the fabric limit
The guide recommends the hottest temperature allowed by the clothing label, which is a limit rather than a universal hot-wash command. Load size and correct dosing remain part of the process. A robust cotton item may permit treatment that another garment does not, so the stain type should not be the only factor used to choose the cycle.
