Khao pad (ข้าวผัด) is Thai fried rice — one of the most common everyday Thai dishes. Day-old cooked jasmine rice is stir-fried in a hot wok with egg, protein (chicken, prawn, pork, or crab), garlic, onion, and a seasoning combination of fish sauce (nam pla), light soy sauce, and oyster sauce. Some versions add tomato or fresh herbs. A spilled plate of khao pad deposits cooked rice grains across the carpet, embedded in a light coating of sauce and egg fat. The primary challenges are: cooked rice grains embedding between carpet fibres (they become sticky as they cool and can press into the pile base), fish sauce odour, and the combined soy/oyster sauce colour. Khao pad is lighter in colour than pad see ew (no dark soy) and less oily overall than many wok dishes, but the cooked rice starch challenge is significant — rice starch dries quickly and can adhere strongly to carpet fibres.
Khao pad cleaning steps
- Scoop up the bulk of the rice grains with a spoon before they press further into the pile. Then vacuum the area to remove remaining loose grains.
- Blot the liquid sauce component.
- Apply cornflour for the wok oil and egg fat. One to two rounds.
- Apply cold water and blot to loosen the rice starch and dilute the fish sauce and soy sauce.
- Apply dish soap solution and blot.
- Apply enzyme cleaner for 20 minutes — rice starch (amylase component), egg protein, and prawn or chicken protein if present. Fish sauce protein compounds also benefit from enzyme dwell time.
- Rinse thoroughly.
- Apply hydrogen peroxide (3%) for colour. Light soy and oyster sauce colour: one to two rounds on light carpet. Fish sauce itself adds minimal colour (it is a pale amber liquid) — the colour treatment is primarily for the oyster sauce brown component.
- Apply baking soda dry overnight for the fish sauce odour. Fish sauce fermented-fish volatile compounds persist in carpet pile after the visible treatment is complete. One overnight baking soda treatment is usually sufficient.
Cooked rice grains — scoop and vacuum before any liquid treatment
Cooked jasmine rice grains are sticky when fresh and become even stickier as they cool to room temperature. Rice starch (amylose and amylopectin) gelatinises during cooking and re-sets as the rice cools — on carpet, this means grains that are not removed while still warm and loose will begin to adhere to carpet fibres within minutes. Vacuuming after scooping removes the remaining grain fragments from between fibres. Once liquid is applied to the spill area, any remaining rice grains absorb the liquid and swell slightly, pressing even more tightly into the pile base. The grain removal step is therefore strictly before any liquid treatment. If some grains have already dried onto the carpet, dampen them with cold water first (30 seconds to a minute), then vacuum or scrape — rehydrated grains release from fibres more easily than fully dried ones.
Fish sauce odour or rice starch residue from khao pad persisting in carpet?
Embedded cooked rice starch and fermented fish sauce compounds that have penetrated carpet backing may need professional hot-water extraction for complete resolution.

Frequently asked
The khao pad was khao pad poo (crab fried rice) and the crab meat left a faint pinkish colour on the carpet alongside the sauce staining. Does crab meat leave a separate colour stain?
Crab meat contains astaxanthin (a carotenoid pigment responsible for the pink-orange colour of cooked crustaceans) — the same pigment found in prawns and lobster. A faint pinkish mark from crab meat contact is from this astaxanthin. The pink colour responds to hydrogen peroxide — the same one to two rounds applied for the soy/oyster sauce colour will also address the crab astaxanthin pink. In practice, the crab colour is lighter and less persistent than the oyster sauce brown, so if the oyster sauce colour clears after two rounds, the crab pink will have cleared alongside it or earlier. The crab protein is addressed by the enzyme step alongside the egg protein.
The khao pad was served with a small dish of nam pla prik (fish sauce with sliced bird's eye chillies) on the side as a condiment, and the entire dish tipped including the condiment. The chilli condiment spilled separately onto a clean area of carpet. Do I treat the nam pla prik zone separately?
Nam pla prik (fish sauce + bird's eye chillies) is fish sauce with sliced chilli rings floating in it. It has two components that stain: the fish sauce liquid (pale amber, strong fermented odour) and the chilli slices (minimal red colour from the cut chilli flesh and seeds). The nam pla prik zone is treated as a fish sauce spill with a minor chilli component — blot immediately, apply cold water, enzyme cleaner (20 minutes), rinse, then one hydrogen peroxide round for any chilli red colour, and baking soda overnight for the fish sauce odour. Treat the nam pla prik zone and the main khao pad zone as separate stains, applying the full sequence to each independently. The chilli slices should be picked up before any liquid treatment.
The khao pad had pineapple pieces in it (khao pad sapparod style). The pineapple juice has a distinct smell and the pineapple pieces left a faint yellow mark. Is pineapple juice on carpet a significant stain?
Pineapple juice is mildly acidic (pH around 3.5) and has a faint yellow colour from its natural pigments. On carpet, pineapple juice is a minor stain — the colour is light and responds easily to cold water rinse and hydrogen peroxide (one round is sufficient). The more relevant consideration is the bromelain enzyme content of fresh pineapple: bromelain is a proteolytic enzyme that can, with extended contact time on protein-based carpet fibres (wool, nylon), potentially affect the fibre surface. Blotting and rinsing the pineapple contact areas promptly prevents extended bromelain contact. For the pineapple zone specifically, apply cold water rinse immediately, then proceed with the normal khao pad sequence — the bromelain concern is addressed by prompt rinsing, not by an additional treatment step.
