Zhug is a blended sauce — all the fresh herbs and chillies are processed together with olive oil, releasing a high volume of chlorophyll from the coriander and parsley. Green chillies also contain chlorophyll, adding to the green pigment load. Unlike dried red chilli sauces, zhug has minimal carotenoid colour — the stain is primarily the deep, bright green of concentrated herb chlorophyll in an olive oil carrier. The cardamom in zhug is distinctive: it adds a strong aromatic volatile compound (cineole, terpinyl acetate) that can persist in carpet after the visual stain is removed.
Treatment Steps
- Blot up as much sauce as possible with dry paper towels — do not rub.
- Apply cornflour over the stain to absorb the olive oil base; leave 5–10 minutes, then vacuum.
- Apply dish soap solution (one teaspoon per two cups warm water) and blot — chlorophyll is fat-soluble and is emulsified and lifted with the olive oil by dish soap surfactant.
- Apply enzyme cleaner for 15 minutes for the garlic, coriander protein, and cumin residue.
- Rinse with cold water blotting.
- For any remaining green tinge on light carpet: a second dish soap round with warm water, or a diluted hydrogen peroxide application (3%, 1:3 with water, 5 minutes contact).
- For cardamom aroma: baking soda applied after drying, left 30–60 minutes, then vacuumed.
Green chlorophyll stain vs. the dish soap step
The intense bright green of zhug is almost entirely from chlorophyll dissolved in olive oil. Because chlorophyll is fat-soluble, the dish soap step (which emulsifies the olive oil) simultaneously removes the majority of the green colour — the dish soap and colour removal happen as one step rather than two. After thorough blotting of the dish soap application, a significant colour reduction should be visible. Any remaining green after the first dish soap round is residual chlorophyll pigment that responds to a second dish soap application rather than requiring a specialist stain treatment.

Frequently asked
Zhug was made with a lot of fresh green chillies and the stain is both bright green and has left a burning sensation on my skin when I blotted it. Is capsaicin in green chillies treated the same as in red chillies?
Capsaicin is capsaicin regardless of whether it comes from green or red chillies — the same chemistry applies. Capsaicin is fat-soluble and is emulsified and removed by the dish soap step. The burning sensation on skin from contact with concentrated zhug during cleaning is from the capsaicin in the green chilli. Wearing rubber gloves when blotting zhug stains protects the skin. Dish soap and water on the skin removes capsaicin from hands if contact occurs. The carpet treatment does not need to be adjusted for the capsaicin component — the dish soap emulsification step that removes the olive oil simultaneously removes the capsaicin dissolved in it.
Red zhug (zhug adom — the red version made with red chillies) spilled on the carpet instead of the usual green version. Is the treatment different?
Red zhug (zhug adom) replaces the green chillies and herbs with dried red chillies, giving it a deep red-orange colour from chilli carotenoids rather than the green chlorophyll of the green version. The olive oil base and garlic and spice components are the same. The treatment is identical but the colour chemistry changes: instead of chlorophyll (which lifts with the dish soap emulsification), you are dealing with red carotenoid pigment (also fat-soluble, also lifted with dish soap emulsification). For red zhug, the hydrogen peroxide step is more likely to be needed for residual orange-red colour on light carpet than for green zhug.
The zhug was served on the side with falafel and both the falafel pieces and the sauce fell on the carpet together. Do I treat the solid falafel first?
Yes — remove the solid falafel pieces first, before any liquid is applied. Falafel is a fried chickpea patty: it is oil-saturated from frying and will crumble into the carpet pile if wetted before removal. Pick up the falafel pieces by hand, then vacuum to remove crumble fragments. After the solid falafel is removed, treat the combined stain — the falafel and zhug share an oil component (the olive oil from the zhug plus the frying oil from the falafel), so the cornflour absorption step addresses both. The chickpea starch and herb protein from the falafel are treated along with the zhug residue in the dish soap and enzyme cleaner steps. The enzyme cleaner is particularly important for the chickpea protein from the falafel.
