The Two Thickeners in Lomi and Why They Create Different Challenges
Standard noodle soups like mami or tinola have a thin, watery broth that spreads rapidly but is easy to blot. Lomi broth is thickened by two components: beaten egg whisked into the soup creates protein strands suspended throughout the broth (like a hot and sour soup), and cornstarch dissolved in the cooking liquid gelatinises at high temperature to thicken the broth to a near-gravy consistency. These two thickeners create conflicting treatment requirements: the egg protein strands require cold water treatment only (heat sets them permanently), while the cornstarch gel is most effectively broken down by warm water and amylase enzyme. Cold water is the correct priority because egg protein heat-setting is irreversible.
Stain Components at a Glance
- Egg protein strands (beaten egg in broth) — from egg whisked into the soup; albumin and yolk lecithin suspended throughout the thick broth; sets permanently with heat
- Cornstarch thickener — gelatinised starch from the dissolved cornstarch added to the broth; cools to a sticky, adhesive gel
- Thick egg noodle (lomi noodle) — fresh thick wheat-egg noodle; higher egg content than dried wheat noodles; contributes egg albumin to the stain at the noodle landing point
- Pork protein — from the pork slices or pork liver in the soup; responds to enzyme treatment
- Shrimp TMA — from any shrimp in the soup; standard seafood amino odour
- Chicken or pork broth — the base broth; chicken or pork fat, dissolved protein
- Fish sauce or soy sauce seasoning — TMA from patis or minor soy melanoidins depending on the recipe
Step 1 — Absorb Thick Broth With Paper Towels
Lomi broth is thick and does not spread as rapidly as thin soups — press paper towels firmly onto the full spill area. The thick broth will absorb into the towels more slowly than water. Remove noodle pieces and pork slices by hand. The thick noodles (lomi noodles) are fresh and firm — they can be picked up without pressing them into the pile.
Cold Water Only — Egg Protein in the Broth Sets Permanently With Heat
Lomi broth has beaten egg stirred throughout — egg albumin and yolk lecithin are suspended in every part of the thick broth, not just at the egg landing point. This means the cold water rule applies to the entire spill area, not only where visible egg pieces landed. Hot water, warm water above approximately 60 degrees Celsius, or steam mops applied anywhere in the lomi spill zone will cook the egg protein into the carpet fibres. Use cold water for all rinse steps. The cornstarch starch can be addressed later with amylase enzyme despite the cold temperature — enzyme activity on starch does not require heat.
Step 2 — Cold Water Rinse for Egg-Safe Dilution
Apply cold water to the full spill area. Cold water dilutes the egg protein and cornstarch broth, keeping both in a removable state. Blot out thoroughly. The broth will thin as it is diluted, making subsequent blotting more effective. Repeat the cold water rinse once.
Step 3 — Baking Soda for Pork-Chicken Fat
Apply baking soda paste to the fat landing zone. Lomi typically uses a pork or chicken-based broth with pork fat rendered in — moderate fat load. Leave for 20 minutes, vacuum.
Step 4 — Protease Enzyme (Cold Water Dilution) for Egg and Pork Protein
Apply protease enzyme cleaner using cold water dilution to the full stain area. The enzyme addresses: the egg albumin and yolk lecithin protein from the broth and the fresh noodles, the pork protein, the shrimp amino compounds, and the fish sauce or soy protein residue. Use cold water dilution throughout — keep temperature cold to protect the egg protein from heat setting during the treatment. Allow 15 minutes dwell. Blot out and rinse cold.
Step 5 — Dish Soap for Residual Fat
Apply diluted dish soap to the fat zone. Emulsifies pork and chicken fat residue. Allow two to three minutes, blot and rinse cold.
Step 6 — Warm Water Flush for Cornstarch Starch Residue
After the enzyme step has addressed the egg protein, it is now safe to apply warm water to the cornstarch residue zone. Warm water re-liquefies the cornstarch gel and allows the remaining starch to be blotted out. If an amylase-containing enzyme product is available, apply it now at warm water dilution and allow 10 minutes dwell — amylase is more effective at warm temperature and the egg protein risk has already been addressed. Blot and rinse.
Step 7 — Hydrogen Peroxide (If Soy Tinting or Pork Liver Residue)
Batangas lomi is typically a pale broth — no soy melanoidin chromophore in the traditional recipe. Apply H2O2 only if a brown tint from soy seasoning, pork liver (haem compounds), or the egg yolk carotenoids remains after the enzyme step has dried. Apply 3% H2O2 targeted to the discoloured zone, allow 8 minutes, blot and rinse cold.
Step 8 — Extended Baking Soda for Shrimp and Fish Sauce Odour
Apply dry baking soda across the full treated area. Leave for two hours for TMA from the shrimp and fish sauce components. Vacuum and ventilate.
Need a Local Carpet Cleaning Specialist in the Sutherland Shire?
Lomi's egg-thickened broth distributed throughout a large spill area is one of the trickiest cold-water scenarios — any warm contact anywhere in the spill zone risks cooking the egg protein in. If egg protein has set from accidental warm contact, or the cornstarch gel has fully dried into the pile structure, a local specialist can apply professional enzyme extraction to address both.

Frequently asked
How is lomi different from mami for carpet treatment?
Three key differences. First, lomi has beaten egg throughout the broth — making the cold water rule apply to the entire spill area rather than just where a fried egg piece lands (as in tapsilog). Second, lomi broth is thickened with cornstarch — creating an adhesive starchy gel that mami does not have. Third, traditional lomi does not use soy sauce seasoning, so there is typically no melanoidin chromophore and H2O2 is optional. Overall: lomi is more physically adhesive and has a more critical temperature-management requirement than mami, but easier to treat for colour.
I poured warm water on lomi spill before reading this. What do I do?
Do not pour more warm water. Apply cold water from this point forward. If the egg has already begun to set from the warm water contact, the enzyme step is now more critical — protease enzyme applied cold can still cleave partially set egg albumin peptide bonds. Allow a longer enzyme dwell (20 minutes rather than 15) and repeat if necessary. Set egg protein creates a translucent, slightly stiff area in the carpet pile — if this is visible after treatment, it is likely in the backing and may require professional hot-water extraction.
What makes lomi noodles different from mami noodles for stain purposes?
Lomi noodles are fresh, thick, and high in egg content — significantly more egg than dried mami wheat noodles. This means the noodle itself contributes a meaningful egg albumin load to the stain at the noodle landing point, not just the broth. The thick noodles are easier to pick up (they do not flatten onto the pile like sotanghon glass noodles), but the egg protein residue at the noodle contact zone requires the same cold water and enzyme treatment as the broth zone.
Does the cornstarch thickener cause the same pile adhesion issue as glass noodle starch?
Similar mechanism, different texture. Cornstarch gelatinises at around 62 to 72 degrees Celsius and cools to a smooth, sticky gel. Glass noodle mung bean starch gelatinises at lower temperature and has a rubbery, adhesive texture when set. Both require warm water to re-liquefy and both benefit from amylase enzyme. Cornstarch gel is slightly easier to remove than mung bean gel — it does not bond to individual fibres as strongly. The main difference is that cornstarch is distributed throughout the entire lomi broth, while mung bean starch is concentrated in the glass noodles themselves.
