What Malatang Leaves on Carpet
Malatang (麻辣烫) is a popular Sichuan street food version of hot pot — a single-serving, customisable spicy broth in which individually selected ingredients (meat slices, tofu varieties, fish balls, mushrooms, vegetables, offal, noodles) are simmered. The name refers to the two defining flavour characteristics: 麻 (má — the numbing, tingling sensation from Sichuan peppercorns, caused by the compound hydroxy-alpha-sanshool) and 辣 (là — intense chilli heat). The broth is built on a heavy base of chilli oil, doubanjiang (fermented broad bean and chilli paste from Pixian — the key flavouring in Sichuan cooking), beef tallow, Sichuan peppercorns, dried chillies, fermented black beans, and aromatics. On carpet, malatang is one of the most challenging hot pot stains: the chilli oil creates an intensely deep red-orange stain from concentrated carotenoid pigments (capsanthin, capsorubin) that are colour-fast and oil-soluble — requiring two to three hydrogen peroxide rounds. The beef tallow base is harder to remove than most cooking oils, requiring three cornflour rounds. The doubanjiang adds a dark reddish-brown fermented paste residue with additional protein and starch.
What You Will Need
- Spoon (for solid ingredients — meat, tofu, fish balls, noodles)
- Cornflour (three rounds for beef tallow and chilli oil fat)
- Cold water
- Clean white cloths or paper towels
- Enzyme carpet cleaner (protease enzyme)
- Dish soap (one teaspoon per 250ml cold water)
- Hydrogen peroxide 3% (two to three rounds for chilli oil colour)
- Baking soda (overnight for chilli and Sichuan peppercorn aroma)
Step 1: Remove Solid Ingredients
Collect all solid malatang ingredients with a spoon — meat slices, fish balls, tofu pieces, noodles, mushrooms, and vegetables. The heavy chilli oil broth will have coated all of these pieces. Collect them from the outer edge of the spill inward to avoid spreading the very fluid chilli oil broth further across the carpet.
Step 2: Blot the Chilli Oil Broth
Blot the deep red malatang broth firmly from the outer edge inward. The chilli oil broth is a very fluid, deeply pigmented oil — it spreads readily and penetrates carpet fibres quickly. Blotting cloths will immediately show an intense orange-red from the chilli oil carotenoids. Apply cold water and blot three times. The oil component of malatang broth means water dilution has limited effect before the cornflour steps, but reducing the surface concentration before the absorptive treatment helps.
Step 3: Apply Cornflour for Beef Tallow and Chilli Oil Fat (Three Rounds)
Malatang broth has an extremely high fat load from two sources: beef tallow (the traditional fat base, used in large quantities — a ladleful of hot malatang broth typically contains a significant tallow fraction) and chilli oil (itself a fat — chilli pigments are dissolved in oil). Beef tallow is a hard saturated fat (higher in stearic and palmitic acid than most cooking oils) that sets firmer when cool and is harder for detergent to emulsify. Apply cornflour generously, allow 20 minutes, and vacuum. Repeat twice more — three rounds in total. After the third round, apply cold water and blot.
Step 4: Apply Enzyme Cleaner for Meat, Tofu, and Bean Paste Protein
Apply cold water and blot. Apply enzyme carpet cleaner and allow 20 minutes. Malatang broth contains protein from the doubanjiang (fermented broad beans), meat broth components, and any solid ingredients that have dissolved into the broth. Fish ball and meat protein from the ingredients responds to the enzyme protease step. Follow with dish soap solution to emulsify the remaining chilli oil and tallow residue after the enzyme step. Blot and rinse.
Step 5: Treat the Chilli Oil Red-Orange Colour (Two to Three Rounds)
The malatang chilli oil stain is among the most colour-fast of all cooking stains. Chilli carotenoids (capsanthin and capsorubin — the pigments responsible for the red colour of both chilli peppers and paprika) are oil-soluble, which means they bind deeply to carpet fibres along with the tallow and oil carrier. After the cornflour and enzyme steps remove the fat carrier, the residual carotenoid pigment is addressed with hydrogen peroxide. Apply hydrogen peroxide 3% and allow 10 minutes. Blot and rinse. Allow to dry, then apply a second round. Most malatang stains require two rounds — very heavy chilli oil deposits may need a third. The deep red lightens progressively to orange-yellow to a faint yellow-beige. A residual warm yellow on pale carpet after two rounds typically continues to fade further over one to two days.
Step 6: Treat the Chilli and Sichuan Peppercorn Aroma Overnight
Apply baking soda over the fully dried stain area and allow overnight. The Sichuan peppercorn aromatic oils (containing linalool, geraniol, and the numbing compound hydroxy-alpha-sanshool) and the dried chilli volatile capsaicinoids leave a distinctive, persistent, deep spice aroma on carpet. The fermented doubanjiang also contributes a complex fermented aroma that benefits from overnight baking soda treatment.

Frequently asked
The malatang I ordered used a vegetarian broth base with vegetable oil instead of beef tallow — many malatang shops now offer a non-tallow option. Does the absence of beef tallow make the stain significantly easier to treat?
Yes — the fat component is meaningfully different. Beef tallow is a hard saturated animal fat (predominantly stearic acid C18:0 and palmitic acid C16:0) that sets firmly when cool and requires more cornflour absorption cycles and stronger emulsification than vegetable oils. Vegetable oil-based malatang broth is primarily unsaturated and semi-solid at room temperature — it responds to two cornflour rounds rather than three. The chilli oil component (the chilli pigment carrier) is typically a vegetable oil such as rapeseed or soya in both tallow and non-tallow versions — so the colour-fast chilli carotenoid stain and the two to three peroxide rounds remain unchanged regardless of the fat base. For vegetarian tallow-free malatang: two cornflour rounds, same enzyme and peroxide protocol as standard malatang.
The spill included a large amount of zhima sauce (芝麻酱 — Chinese sesame paste sauce) that I had mixed into my bowl as a dip. Zhima sauce is a thick, grey-brown sesame paste similar to tahini but with a stronger roasted sesame flavour. The sauce mixed with the malatang broth in the spill. Does sesame paste add a significant additional stain component?
Zhima sauce (Chinese roasted sesame paste) is very similar in composition to tahini — approximately 50–55% fat (sesame oil) and 20–25% protein (sesame seed protein), with a distinctive grey-brown colour from the roasted sesame. Mixed with malatang broth, the sesame paste adds: (1) additional sesame oil fat to the already heavy tallow and chilli oil load — plan for a fourth cornflour round for zhima-plus-malatang; (2) sesame protein that responds to the enzyme protease step; (3) a grey-brown sesame roasting colour that is very mild — typically obscured entirely by the much more intense chilli oil red, and any residual grey-brown after the peroxide rounds is minimal. The dominant stain character remains the malatang chilli oil red. The practical adjustment is a fourth cornflour round if zhima sauce was mixed in a significant quantity.
My malatang had extra-spicy broth — I asked for the highest spice level (最辣, zuì là). The broth was almost black from the quantity of dried chillies and doubanjiang. Very dark, nearly opaque. Does highest-spice-level malatang leave a dramatically darker stain?
Extra-spicy malatang at the highest spice level uses significantly more doubanjiang and dried chillies than standard. The doubanjiang (fermented Pixian chilli bean paste) is dark reddish-brown from both the chilli pigments and the Maillard browning from the long fermentation process — in very high quantities it pushes the broth colour from orange-red to a very dark, almost brownish-red. On carpet, maximum-spice malatang creates a darker stain than standard — the additional doubanjiang contributes melanoidin compounds from the fermentation, adding a dark brown layer on top of the chilli carotenoid orange-red. Plan for three hydrogen peroxide rounds as a minimum rather than treating two as sufficient. The large quantity of dried chilli also means a stronger capsaicin load in the carpet fibres, which means the chilli-burning sensation can be an irritant if the area is walked on in bare feet before treatment — address treatment promptly and rinse thoroughly after each peroxide step.
