Lo-Chlor is Australia's most trusted specialist pool and spa chemical manufacturer globally recognised and exporting to 25+ countries. Their range covers algaecides, clarifiers, phosphate removers, stain treatments, stabilisers, spa care, equipment aids and more, every product formulated for Australian water chemistry and climate.
Lo-Chlor Fume Away is a liquid acid fume inhibitor and corrosion protector — added directly to hydrochloric (muriatic) acid before use to instantly neutralise the dangerous fumes produced when acid is applied to pools and spas.
Hydrochloric acid (HCl) is one of the most commonly used pool chemicals for pH reduction and surface cleaning — and one of the most hazardous. The fumes produced during application cause respiratory irritation, corrode metal surfaces and equipment, and degrade pool infrastructure over time. Fume Away's surfactant-based formula suppresses fuming on contact, making acid work dramatically safer.
Lo-Chlor Fume Away details
Extinguishes hydrochloric acid fumes instantly on addition
Inhibits the corrosive characteristics of hydrochloric acid
Protects metal pool surfaces, fittings and equipment from acid corrosion
Contains a detergent that assists with removal of oils and greases
Reduces streaking and plaster loss during acid washing
Saves time and reduces wear on pool infrastructure
1L — sufficient for multiple acid dosing treatments
Fume Away is used alongside hydrochloric acid — it's not a standalone pool treatment. For overall scale and stain prevention that reduces how often acid washing is needed, Lo-Chlor Stain & Scale Defence weekly reduces calcium buildup on surfaces significantly.
🔍 When to use it▾
Fume Away is used alongside hydrochloric acid for pool and spa pH reduction and acid washing.
💊pH reduction (regular dosing)▾
✓ Add to acid before every application
Add Fume Away to the HCl before diluting and adding to the pool. Reduces fume exposure for the person handling the acid.
🧹Acid washing▾
✓ Essential for safe acid washing
When acid washing pool surfaces, Fume Away significantly reduces the fume hazard that makes acid washing particularly unpleasant and potentially dangerous.
🔩Protecting metal fittings▾
✓ Reduces corrosion to adjacent metal
Pool handrails, ladders, filter lids and nearby metal equipment are less affected by acid fumes when Fume Away is used.
🧂Salt pools▾
✓ Particularly valuable for salt systems
Salt cell housings and associated fittings are prone to acid corrosion. Fume Away during acid dosing reduces this risk.
🏊All pool surfaces▾
✓ Reduces streaking and plaster impact
The formula reduces streaking on plaster and pebblecrete during acid washing, producing a more even result.
⚠Standalone use▾
✗ Must be used with acid — not a standalone product
Fume Away is an additive for hydrochloric acid — it has no standalone pool treatment function.
💊 How to use▾
Add Fume Away to the hydrochloric acid before using. Do not add to pool water directly without acid.
pH reduction dose
50 ml
per litre of HCl
Add 50ml of Fume Away to each litre of HCl before diluting and applying to the pool.
Acid washing
100 ml
per litre of HCl
Use double the dose during full acid washing for maximum fume suppression and corrosion protection.
Always dilute acid
Mix acid into water
never water into acid
Always add acid to water, never the reverse. Add Fume Away to the acid first, then dilute into a bucket of water.
Storage
Keep sealed
cool and dry
Store Fume Away in a cool, dry place away from other chemicals. Check the product label for full safety and storage instructions.
❓ FAQ▾
Does Fume Away actually work?▾
Yes — Fume Away's surfactant formula suppresses the volatile hydrogen chloride gas released when HCl contacts air and moisture. Pool professionals who use it consistently report significantly reduced fume exposure during acid dosing.
Is it safe to handle?▾
Fume Away is safer to handle than HCl but is still a chemical product — wear appropriate PPE (gloves, eye protection) when handling any acid or acid-related product. Always work in a ventilated area.
Will it affect my pool water balance?▾
No — the small amount of Fume Away added to the acid dissolves fully and has no measurable impact on pH, alkalinity or any other water parameter.
