Grease and cooking-oil stains: first aid now, and what actually gets it out
Fresh, this normally comes out at home with the steps below. Set or previously scrubbed, it usually still comes out with the right professional chemistry. Success depends on the fiber: 1 of 5 common carpet fibers rate high, 4 medium — see the table.
Do this now
Blot excess with a dry towel; don't press hard.
Cover the spot with baking soda or cornstarch, leave 15 minutes to absorb, vacuum.
Dab with a solution of clear dish soap (a degreaser) in warm — not hot — water. Blot, repeat.
Rinse with plain water and dry with a weighted towel. A faint ring on polyester or olefin means oil is still in the fiber — that's the professional step.
Don't do this
Plain water first. It spreads the oil.
Hot water on olefin — the fiber is heat-sensitive.
Rubbing, which drives oil into the base of the pile.
Why it works (and why the usual advice doesn't)
Oil doesn't dissolve in water — it has to be either absorbed while fresh, dissolved with a solvent, or emulsified by a detergent that can grab both oil and water. That is why water alone spreads a grease spot into a bigger, paler ring. Fiber matters more here than for almost any other stain: nylon releases oil, while polyester, olefin and triexta are oleophilic — they attract and hold oil — which is why the traffic lanes on those carpets go gray from foot oil even when there's no spill.
Will it come out? Depends on the fiber
The same grease and cooking-oil stains behaves differently on each carpet fiber. Flip a corner or check the closet remnant — the fiber is usually printed on the backing label.
| Fiber | Outlook | Why |
|---|---|---|
| Nylon | High | Nylon doesn't hold oil. Solvent plus degreaser removes it fully. |
| Polyester | Medium | Oleophilic fiber. Comes out with solvent work; very old set grease can leave a faint dull spot. |
| Olefin (polypropylene) | Medium | Attracts oil strongly and is heat-sensitive. Solvent-based removal, no hot water, no friction. |
| Triexta (SmartStrand) | Medium | Oil-loving fiber like polyester. Solvent step required. |
| Wool | Medium | Wool handles oil reasonably but must be cleaned cool and near-neutral; strong alkaline degreasers damage it. |
High = normally removed fully. Medium = usually removed, some risk of a faint ghost. Low = partial at best. Permanent = dye or fiber damage; repair options only.
The Tampa factor
Sunscreen, cooking oil and body oil in a humid climate never fully dry — they stay soft and collect sand. On a polyester carpet from the lanai door to the kitchen that adds up to a gray path in months. Solvent pre-treatment on the lanes is the fix, not stronger detergent.
What we do when you call
A dry solvent applied to the spot dissolves the oil without water, then an alkaline degreasing pre-spray emulsifies what's left, and hot-water extraction removes it. On polyester, olefin and triexta we repeat the solvent step because those fibers hold oil in the fiber itself. Whole-room traffic lanes on those carpets get a solvent-boosted pre-conditioner, which is the difference between lanes that come up and lanes that don't.
