Can Grease Stains Be Removed From Carpet?

The answer

Many grease stains can be treated using CRI's grease spot-removal procedure, although stubborn or old stains may require repeated treatment or professional cleaning.

Why

CRI advises acting quickly, blotting liquids or gently scraping semi-solids, pretesting any spot-removal solution, applying small amounts to a white cloth, working gently from the edge toward the center, and rinsing the area after the spill is removed.

When it is usually OK

• The grease spill is treated promptly.
• Excess material can be blotted or gently scraped before applying cleaner.
• The selected spot solution is pretested without color or texture damage.
• The area is rinsed and dried after treatment.

When you should not

• Do not rub or aggressively scrub the grease into the fibers.
• Do not pour solvent directly onto carpet backing.
• Do not use stronger solution concentrations than CRI recommends.
• Do not continue DIY treatment if color transfer or fiber damage appears.

Risks and exceptions

• Solvents can damage carpet backing if poured directly onto it.
• Cleaning residue can attract new soil if not rinsed out.
• Some old or stubborn stains may not be fully removable with household spot treatment.

Best practice

Follow the CRI grease procedure in sequence: remove excess material, pretest, use small amounts of the appropriate treatment, blot gently, rinse residues, and stop if the carpet changes color or texture.

Alternatives

• Use a CRI-approved spot-removal product.
• Use a professional carpet cleaner for stubborn grease.
• Use a dry absorbent cleaning compound where the CRI procedure allows it.
