Persillade has three staining components that each require a different treatment step: parsley chlorophyll (fat-soluble green pigment, dissolved in and lifted with the fat during dish soap emulsification), garlic allicin and sulphur compounds (adsorb to carpet fibres, require enzyme cleaner and baking soda for removal), and a fat base of butter or olive oil (wicks into the pile, requires cornflour absorption before water-based treatment). The garlic smell in persillade is raw rather than cooked, meaning the allicin and sulphur compound concentration is higher than in a garlic sauce that has been heated.
Treatment Steps
- Blot up excess persillade with dry paper towels — do not rub.
- If butter-based and the butter has re-set (solidified), scrape from the carpet surface with a blunt knife before the cornflour step.
- Apply cornflour to absorb butter or olive oil; leave 5–10 minutes, then vacuum.
- Apply dish soap solution (one teaspoon per two cups warm water) and blot — emulsifies fat and lifts fat-soluble parsley chlorophyll simultaneously.
- Apply enzyme cleaner for 15–20 minutes — breaks down garlic sulphur compounds.
- Rinse with cold water blotting.
- Apply baking soda after partial drying; leave 30–60 minutes; vacuum — adsorbs residual garlic volatile compounds.
Butter-based persillade sets on cooling — scrape first
Butter-based persillade (as in garlic butter for escargots or steak) is liquid when warm but solidifies as it cools. If the persillade was applied hot and has cooled on the carpet, the butter has likely firmed up. Gently scrape the solidified layer with a blunt knife before applying cornflour — removing the solid layer first prevents the cornflour from being wasted absorbing solid fat on the surface rather than the liquid fat deeper in the pile.

Frequently asked
Garlic butter persillade dripped from an escargot dish onto the carpet during serving. Is escargot garlic butter treated the same as persillade?
Escargot garlic butter is compound butter — butter mixed with persillade, sometimes with added shallot or Pernod. The staining chemistry is the same: dairy fat and milk proteins, parsley chlorophyll (fat-soluble, lifted with the fat), and garlic sulphur compounds. The snail itself, if it also fell, adds a small amount of mollusc protein addressed by the enzyme cleaner step alongside the dairy protein. Treatment is identical: scrape solidified butter, cornflour for oil absorption, dish soap for emulsification and chlorophyll removal, enzyme cleaner for garlic and protein, baking soda for smell.
Persillade breadcrumb crust fell from a rack of lamb onto the carpet. The crust contains breadcrumbs, parsley, garlic, and olive oil. How do I handle the solid crust on carpet?
Pick up the crust pieces by hand and vacuum the breadcrumb fragments before any liquid is applied — applying water before removing breadcrumbs causes them to clump in the pile. After vacuuming, the remaining stain is the olive oil, parsley, and garlic that transferred to the fibres. Treat with cornflour for oil absorption, dish soap for chlorophyll and oil emulsification, enzyme cleaner for garlic, and cold water rinse. Any lamb fat that accompanied the crust is addressed in the cornflour and dish soap steps.
The garlic smell from persillade is still present after dish soap and water cleaning. What do I do?
Dish soap and water alone do not remove garlic sulphur compounds — they address the oil and chlorophyll components only. Garlic smell requires enzyme cleaner (apply to a slightly dampened area, leave 20 minutes, rinse) followed by overnight baking soda (apply, leave overnight, vacuum). This two-step sequence breaks down the organic sulphur precursors (enzyme) and adsorbs the residual volatile breakdown products (baking soda). Both steps are needed — enzyme alone or baking soda alone leaves a partial result.
