DualSan Foam — Mould and Decontaminant Cleaner

From large-scale disaster recovery to backyard decks to commercial kitchens, DualSan Foam is built to overcome tough mould and organic soils.

DualSan Foam is a powerful, alkaline sanitising degreaser designed for a wide range of applications including large-scale mould and flood clean-ups, food manufacturing and commercial kitchens. Its formulation combines foaming and sanitising action while protecting substrates from corrosion at working dilution. The super-concentrate makes a cost-effective 1:50 dilution.

Read the safety section before you open the container. The working solution is a manageable alkaline cleaner. The concentrate is a corrosive Class 8 dangerous good at pH 13.25. Our page has always carried the signal word DANGER; what it did not carry was the hazard statements, the transport classification, the PPE or the first aid.

Benefits

Exceptional cleaning performance — highly effective on a wide variety of hard surfaces including timber, masonry, plasterboard, steel, stone, tiles and concrete. Removes stubborn grime, mould and contaminants, and efficiently removes organic soiling, food fats, oils, baked-on carbons and general grime.
Powerful sanitisation — a multi-faceted sanitising system targets fungi, bacteria and viruses, giving efficiency in cleaning walls, floors and ceilings.
Food safe formula — meets the requirements of FSANZ 3.2.2 for safe application in food environments.
Free rinse formulation — leaves minimal chemical residue for easy and thorough rinsing.
Low odour in use — contains no added fragrances or solvents, suitable where minimal odour exposure is required.
Surface safe at working dilution — a dual corrosion inhibitor system allows application on rubber, plastics and most painted surfaces. See the metals note under Safety.

Where to Use

Large-scale mould and flood remediation

Kills mould, sanitises and cleans areas impacted by mould and water damage, eliminating harmful micro-organisms and contaminants. For applications requiring swab testing, a follow-up treatment with Biosan II, Percide or Mould Exterminator may be required.

Outdoor and hard surface cleaning

A strong cleaner with powerful soil removal for timber decks, outdoor concrete, tiles and stone, with the added benefit of leaving a sanitised surface.

Food manufacturing and hospitality

Ideal for cleaning walls, floors, ceilings and processing equipment in compliance with food safety standards.

Safe and versatile application

Suitable on enamel, ceramic, plastic, metal, stainless steel, vinyl, rubber and wall tiles. For painted surfaces, particularly vehicle paintwork, conduct a preliminary test before use.

Where DualSan Foam Fits Alongside Biosan II, Percide and Mould Exterminator

Its cleaning action is what sets DualSan Foam apart. The three key advantages are superior cleaning power, cost-effective dilution and foaming action, which make it well suited to flood and biocontamination clean-ups where cleaning is a major component of the job.

For straight mould remediation or decontamination, Biosan II, Percide and Mould Exterminator remain the go-to options. DualSan Foam’s disinfectant strength is theoretically moderately stronger than Biosan II, but DualSan Foam requires rinsing after use.

One difference worth knowing before you specify it: Biosan II (AUST L 332364) and Percide (AUST L 332284) are TGA-listed hospital grade disinfectants. DualSan Foam is a sanitising degreaser and we have found no ARTG listing published for it. If your scope, contract or insurer requires a listed disinfectant, use DualSan Foam for the clean and a listed product for the disinfection step — which is exactly what the swab-testing note above is telling you.

Directions for Use

Dilutions — cleaning

Light to medium duty cleaning — 10 to 30 ml per litre of water
Foam wash, heavy duty cleaning and mould removal — 20 to 40 ml per litre of water

Note: depending on the foam generator unit and the water quality, the dilution for foam washing may need to be altered. Start at 30 ml/L and adjust up or down.

Dilutions — sanitisation

Clean and sanitise in one step — 1:50 (20 ml/L) or stronger
Sanitise a pre-cleaned surface — 1:100 (10 ml/L) or stronger
Mould remediation and biodecontamination — 1:32 (30 ml/L)

Dwell time: allow 10 minutes for optimal sanitisation efficacy, with the surface kept visibly wet. For extensive flood and mould remediation, DualSan Foam delivers cleaning power while eliminating mould and pathogens.

Safety

Our page has always said “Safety: Danger”, which is correct. It did not say what the danger is, what to wear, or what to do about a splash. That is below.

DualSan Foam is classified as a HAZARDOUS CHEMICAL and DANGEROUS GOODS under the Model WHS Regulations and the ADG Code. It is a Poisons Schedule 6 substance.

Signal word: DANGER
H314 — causes severe skin burns and eye damage
H302 — harmful if swallowed
GHS: Serious Eye Damage Category 1; Skin Corrosion/Irritation Category 1B; Acute Toxicity (Oral) Category 4
HAZCHEM code: 2X
pH of the concentrate: 13.25
pH of the working solution: 11.25 to 12.5
Actives: EDTA tetrasodium salt, sodium metasilicate pentahydrate, monoethanolamine, nonylphenol ethoxylate, two proprietary surfactants, a quaternary ammonium compound and a biocide — each below 10%
Transport: UN3266, Class 8, Packing Group II

The two pH figures are both correct and it matters which one you are looking at. 11.25 to 12.5 describes the diluted solution you spray. 13.25 describes what is in the drum. Decanting and dosing is the only step where you handle the concentrate, and it is the step at which people wearing no eye protection get hurt.

Personal protective equipment

The SDS specifies elbow-length butyl or neoprene gloves, chemical goggles and a full face shield, overalls and a PVC apron, with access to an eyewash unit. The face shield is specified in addition to goggles, not instead of them.

First aid

Eyes. Hold the eyelids apart and flush continuously with running water for at least 15 minutes. Obtain medical attention without delay — H314 means eye damage can be permanent.

Skin. Remove contaminated clothing and footwear immediately and flush with large amounts of water. Alkaline burns are often painless at first and deepen over minutes — a splash that does not sting still needs flushing.

Swallowed. H302 applies. Rinse the mouth, do not induce vomiting, and seek medical advice.

Metals, Storage and Mixing

Corrosive to aluminium, tin and zinc. The dual corrosion inhibitor system protects rubber, plastics and painted surfaces at working dilution, but it does not make the product safe on those three metals. Do not decant into or store in aluminium, tin-plated or galvanised containers, and do not leave solution standing on galvanised trims, drains or flashings.

Do not store near acids or oxidising agents. Never mix, and never allow contact in a bucket, foam unit, drain or on the floor, with:

Actichem Grout Restore 60, Grout Restore 20, Tile & Grout Restore, Crete Clean, Rust Remover or any acid rinse or descaler
Actichem Perox, Oxyboost Plus, Chlorosan, Mould Exterminator or any oxidiser or hypochlorite

DualSan Foam contains a quaternary ammonium compound, so the standard QAC rule applies: anionic detergent residue deactivates it. Do not blend it with other detergents, and rinse equipment before changeover.
