Pea soup covers a range of preparations with distinct staining profiles. Fresh blended pea soup (made from fresh or frozen peas blended smooth) has a vivid, intensely bright chlorophyll green colour — one of the most saturated natural food greens in home cooking. Dried split pea soup (made from yellow or green dried split peas) is thicker, more starchy, and less colour-vivid — green split pea soup has a muted grey-green rather than bright green, while yellow split pea soup is golden and has no chlorophyll challenge at all. Split pea soups are almost always made with a ham hock, smoked bacon, or ham stock base, adding rendered fat and smoky compounds. The primary staining considerations are: green colour (chlorophyll from fresh peas or residual pigment from green split peas), pea starch (which dries to a very adhesive crust in carpet pile), and ham or bacon fat from the stock base.
Pea soup cleaning steps
- Scoop the bulk soup mass with a spoon immediately — pea soup starch dries to a hard, adhered crust faster than most soups. Do not let it sit.
- Blot the liquid across the full spread area.
- Apply cornflour for the ham or bacon fat in the stock base. One to two rounds depending on how fatty the soup was.
- Apply cold water and blot to loosen the pea starch and dilute any remaining colour.
- Apply dish soap solution and blot.
- Apply enzyme cleaner for 20 minutes — pea starch (amylase component), pea protein, ham protein (if the soup contained meat pieces).
- Rinse thoroughly.
- Apply hydrogen peroxide (3%) for colour. Fresh blended pea (bright green): one to two rounds on light carpet for the chlorophyll green. Green split pea (muted green): one round is usually sufficient. Yellow split pea: no peroxide step needed — the colour is very pale and resolves with the water and enzyme steps.
- For smoked ham versions: baking soda overnight if a smoky or ham odour lingers after the main treatment.
Fresh pea green vs split pea green — very different colour intensity
Fresh blended pea soup gets its vivid green from intact chlorophyll in freshly cooked peas — the chlorophyll has not had time to degrade as it would in a long-simmered split pea soup. A spill of bright green fresh pea soup on light carpet is one of the more vivid natural food colour stains and should be treated promptly before the chlorophyll oxidises and binds more strongly to carpet fibres. Dried green split pea soup, by contrast, has already undergone chlorophyll degradation during the long slow cooking of the dried peas — the green is duller and the pigment less intense, making it easier to remove. Yellow split pea soup has essentially no green pigment at all. When you assess the colour challenge: bright, vivid green (fresh peas) → two hydrogen peroxide rounds; muted grey-green (split peas) → one round; yellow (yellow split peas) → peroxide not needed.
Pea soup green colour or starch residue persisting in carpet?
Pea starch that has set hard in carpet pile, or chlorophyll pigment that has bonded to light-coloured carpet fibres, may need professional hot-water extraction for complete resolution.

Frequently asked
The pea soup was a Dutch erwtensoep — a very thick, almost paste-like split pea soup with smoked sausage (rookworst) and ham pieces. It is so thick it barely poured. Does extremely thick pea soup penetrate carpet differently from thinner versions?
Erwtensoep (Dutch split pea soup) is one of the thickest common soups — it can set nearly solid when cold. Its extreme thickness means it does not spread across carpet as a thin liquid would; instead it lands as a dense, thick deposit in a smaller area. The higher starch concentration per contact area makes the carpet starch challenge more severe — the starch residue will be thicker and harder when dried. The smoked rookworst sausage adds significant rendered fat (smoked pork fat). Treatment adjustments: scoop with a spoon more aggressively to remove the bulk (there is more dense material to remove than from thin soups), apply three cornflour rounds for the sausage and ham fat, extend enzyme dwell to 25 minutes for the high starch density. The colour challenge is the same as standard green split pea soup — one hydrogen peroxide round for the muted grey-green.
Mushy peas (UK-style processed marrowfat peas) were served as a side dish and tipped onto carpet. Mushy peas have a different starch profile from soup — they are overcooked, almost paste-like marrowfat peas. Are they treated like pea soup?
Mushy peas (processed marrowfat peas cooked soft, often with mint and a little sugar) are very similar to thick split pea soup in staining profile — high starch content, green colour (from marrowfat pea chlorophyll, which is typically a muted green rather than vivid), and minimal fat. The key difference from soup is that mushy peas are even drier and more paste-like — they deposit as a concentrated green paste rather than spreading as a liquid. Scoop up as much as possible with a spoon, then vacuum remaining fragments. Apply cold water to dampen and loosen before the enzyme step. The peroxide step for the green colour: one round is usually sufficient for the muted marrowfat green. Mushy peas are a simpler stain than thick split pea soup because there is no ham or bacon fat component and they cover a smaller spread area.
The pea soup spilled in winter when the room was cold. The soup had partially set to a gel-like consistency before it landed. Does cold-set pea soup remove from carpet differently than hot pea soup?
Cold-set pea soup (when the pea starch has gelled, as split pea soup does at low temperatures) deposits as a thicker, more gel-like mass on carpet rather than a pourable liquid. The gelled mass sits higher in the pile and penetrates less deeply than hot liquid soup — this is actually slightly advantageous for initial removal, as more of the gelled mass can be scooped off the carpet surface before penetration. However, gelled pea starch that has been pressed into the pile (by a foot or the plate) becomes very adhered. To remove: scoop the gelled surface material first, then dampen with warm (not hot) water — warm water re-liquefies the gelled pea starch, making it easier to blot up. Proceed with the normal enzyme and peroxide sequence. The colour treatment is the same regardless of gel temperature.
