Why Mohinga Creates a Golden-Yellow, Fish-Scented Carpet Stain
Mohinga (မုန့်ဟင်းခါး) is Myanmar's national dish — a fragrant, complex rice vermicelli noodle soup traditionally eaten for breakfast across the country. The broth is made from catfish (or other freshwater fish) simmered with lemongrass, onion, garlic, ginger, banana stem, and a generous amount of turmeric, creating a golden-yellow, deeply aromatic soup. The rice vermicelli noodles are served in the broth and topped with crispy golden chickpea fritters (pe kyaw), a halved hard-boiled egg, coriander, spring onion, dried chilli flakes, lime wedges, and fish sauce. Mohinga is served at street stalls, restaurants, and tea shops across Myanmar and is one of the most aromatic and distinctive soups in Southeast Asian cuisine. A mohinga spill creates: a vivid golden-yellow turmeric stain (curcumin), a strong fish broth aroma (trimethylamine from the fish), fine rice vermicelli starch, crispy fritter deep-fry oil, and lemongrass and ginger aromatic compounds.
Turmeric in the Broth: The Vivid Yellow Stain
Turmeric is the signature colouring spice of Burmese cuisine, used generously in mohinga to create the characteristic deep golden-yellow broth. Turmeric's yellow colour comes from curcumin — one of the most persistent food pigments on carpet, as discussed in guides for other turmeric-heavy dishes. On light or cream carpet, mohinga broth creates a vivid golden-yellow stain that is visible from across the room. Blot the broth immediately from the outside inward. Do not scrub — scrubbing spreads the turmeric-laden broth over a larger carpet area and forces it deeper into the pile. After blotting, apply a broad-spectrum enzyme cleaner, rinse, and apply 3% hydrogen peroxide for 25 minutes on light or cream carpet to address the curcumin pigment. A second peroxide application may be needed for a concentrated mohinga broth spill on white or light cream carpet.
Fish Broth Aroma: Trimethylamine Treatment
The catfish-based broth of mohinga has a very distinctive, pronounced fish aroma. Catfish (and other freshwater fish) produce trimethylamine (TMA) — the compound responsible for the characteristic fishy smell — in somewhat higher concentrations than saltwater fish because of their diet and metabolic profile. When the mohinga broth contacts carpet, the TMA and fish protein from the broth create a persistent fishy aroma. After the enzyme step and main cold water rinse, apply a diluted white vinegar rinse (1:5 vinegar to water) specifically to the broth contact zone — vinegar's acetic acid neutralises the alkaline TMA, significantly reducing the aroma. Follow with an overnight baking soda application. Two consecutive overnight baking soda applications are recommended for a significant mohinga broth spill.
Rice Vermicelli Starch and Chickpea Fritter Oil
Mohinga's rice vermicelli noodles are very fine (approximately 1mm diameter) and break into many small pieces when spilled. These fine rice noodle fragments scatter over a wide area and dry into a sticky, slightly translucent starchy residue on carpet that attracts re-soiling dust if not treated. The amylase enzyme step digests the rice starch from the vermicelli. Crispy chickpea fritters (pe kyaw) are made from chickpea flour batter deep-fried in vegetable oil until golden — if they fell with the mohinga bowl, the fritter oil adds a significant deep-fry fat component to the spill. Apply dry cornflour or baking soda to the fritter contact area and allow 20 minutes before vacuuming. The lipase enzyme step addresses both the fish oil from the broth and the fritter frying oil.
Lemongrass, Banana Stem, and Dried Chilli
Lemongrass in mohinga contributes citronellal, geraniol, and nerol — pleasant lemon-citrus volatile compounds that create a distinctive Southeast Asian aroma. Banana stem (the inner core of the banana plant trunk) adds a mild starchy, slightly astringent flavour compound and releases a small amount of a sticky, latex-like sap from the plant. Dried red chilli flakes as a topping add capsanthin carotenoid (addressed by the peroxide step alongside the turmeric curcumin). Fish sauce (if used as a condiment or ingredient) adds additional TMA and glutamate to the aroma profile. The overnight baking soda application addresses the lemongrass and ginger aromatic compounds alongside the fish aroma.
Turmeric Yellow Stain or Fish Broth Aroma Remaining?
Mohinga's turmeric curcumin is one of the most persistent food pigments on carpet, and catfish broth aroma is difficult to fully eliminate without professional extraction. We can connect you with a local carpet cleaner in the Sutherland Shire who handles Asian broth-based stains.

Frequently asked
The mohinga was the Mandalay version, which uses a different style of broth — instead of catfish flaked directly into the soup, the Mandalay version uses a thick, dense fermented fish paste (ngapi) dissolved into the broth. The ngapi creates a much more intensely flavoured and pungent broth than the catfish-only Yangon version. Does ngapi-based mohinga create a more difficult aroma challenge on carpet than standard catfish mohinga?
Ngapi-based Mandalay mohinga versus standard Yangon catfish mohinga on carpet: (1) Ngapi is highly concentrated fermented fish — ngapi (ငါးပိ) is Myanmar's fermented fish paste, made by fermenting small fish or shrimp with salt for several months to years. It is extremely pungent and contains very high concentrations of trimethylamine (TMA), volatile fatty acids, and fermentation volatile compounds (indole, skatole from protein breakdown) compared to fresh catfish. An ngapi-based mohinga broth creates a significantly more intense and persistent fish aroma on carpet. (2) Extended aroma treatment required — three consecutive overnight baking soda applications are recommended for ngapi-based mohinga, versus the standard two for regular catfish mohinga. The white vinegar rinse step is particularly important for the ngapi zone (apply a slightly more concentrated dilution of 1:3 rather than 1:5 for the ngapi contact area). (3) Same turmeric stain — the turmeric/curcumin component of the broth is the same regardless of the fish ingredient. The hydrogen peroxide step and duration are unchanged. (4) Higher TMA penetration — ngapi's extremely high TMA concentration means the TMA penetrates more deeply into carpet backing than fresh catfish broth would. Professional hot water extraction is more strongly recommended for a significant ngapi-based mohinga spill on carpet compared to a fresh catfish version. (5) Salt concentration — ngapi is preserved in salt and dissolves additional salt into the broth. Thorough cold water rinsing after the enzyme step is critical to remove dissolved salt and prevent hygroscopic re-soiling (the carpet feeling persistently damp in humid conditions).
The mohinga was served at a Burmese restaurant that adds a topping of lahpet thohk (Burmese fermented tea leaf salad) as an optional extra alongside the standard mohinga toppings. The lahpet thohk contains fermented tea leaves, fried garlic, peanuts, sesame seeds, dried shrimp, tomato, and lime juice. When the bowl spilled, the lahpet thohk topping mixed with the mohinga broth on the carpet. Does fermented tea leaf salad mixed into a mohinga spill add significantly to the stain complexity?
Mohinga with lahpet thohk (fermented tea leaf salad) combined spill on carpet: (1) Fermented tea leaf tannins — lahpet thohk uses tea leaves that have been fermented and preserved in oil (a process unique to Burmese cuisine). Fermented tea leaves contain tea tannins (epigallocatechin gallate and related polyphenols) in concentrated form, similar to the tannins in red wine or black tea but with the added fermentation volatile compounds. Tea tannins create a light brown to olive-green stain on carpet that is addressed by the hydrogen peroxide step alongside the turmeric curcumin. (2) Fried garlic oil — lahpet thohk contains crispy fried garlic, which contributes fried garlic oil (garlic fat-soluble compounds in frying oil) to the spill. The absorbent step and lipase enzyme address this. The garlic aroma from fried garlic is more persistent than raw garlic — two overnight baking soda applications are recommended. (3) Peanut oil and peanut protein — fried peanuts in lahpet thohk contribute peanut oil (approximately 50% fat) and peanut protein (arachins, conarchins). The lipase and protease enzyme steps address both. (4) Dried shrimp — dried shrimp (a common Southeast Asian ingredient) contains concentrated fish protein and a very pungent shrimp aroma compound. The dried shrimp adds another source of fishy/shrimpy TMA and related volatile compounds to the combined spill aroma. This reinforces the need for the vinegar rinse and the extended baking soda treatment for the lahpet mohinga combined spill. (5) Sesame seeds and oil — lahpet thohk uses both sesame seeds and sesame oil. Sesame oil is a very stable, aromatic oil with a distinctive toasted nutty aroma from pyrazine compounds. The lipase enzyme step addresses the oil; the overnight baking soda addresses the toasted sesame aroma.
The mohinga spill happened on a sisal carpet, which is a natural plant-fibre carpet woven from the agave plant. Sisal is known to be particularly sensitive to water and will develop water marks and staining from moisture. How does treating a mohinga spill on sisal carpet differ from treating it on a standard synthetic carpet?
Mohinga spill on sisal carpet versus standard synthetic carpet — critical differences: (1) Water sensitivity of sisal — sisal is a plant cellulose fibre that expands and contracts significantly when wet. Moisture causes sisal fibres to swell, which can cause visible water tide marks as the fibre contracts unevenly during drying. This means all wet treatment steps must use the minimum possible water to avoid tide-marking. Use a barely damp cloth rather than a wet cloth for blotting and rinsing — wring cloths out as thoroughly as possible. (2) No enzyme spray on sisal — liquid enzyme cleaners applied in spray form may cause uneven wetting of sisal and subsequent tide marks. Instead, apply a small amount of enzyme cleaner to a cloth and dab it gently onto the stain zone — avoid soaking the sisal. (3) No hydrogen peroxide on sisal — sisal is a cellulose fibre and may be bleached or weakened by hydrogen peroxide, especially if the carpet has been dyed. Do not apply hydrogen peroxide to sisal. For the turmeric curcumin stain and fish broth colour on sisal, the enzyme treatment (without peroxide) is the safe approach — it will reduce but not fully eliminate the colour on sisal. (4) Fish aroma on sisal — the TMA from the fish broth penetrates sisal fibres readily. The vinegar rinse step must be very controlled (minimal liquid) and the overnight baking soda application is the primary aroma treatment for sisal. (5) Drying sisal promptly is critical — sisal that remains damp for more than a few hours in warm conditions can develop mould and permanently discolour. After treatment, use a fan or ensure strong air circulation. Place dry towels under the sisal carpet to absorb moisture that has penetrated to the backing.
