Descalex Powder
Product code RXSOL-16-1008-010
Formulated to remove rust and water scale build up from boiler evaporators, heat exchangers, cooling systems, pipeline collection system etc
Description
Specifically formulated to remove rust and water scale build up from boiler evaporators, heat exchangers, cooling systems, pipeline collection system etc. It is a superior balance formulated heavy duty POWDER acid containing accelerators, corrosion inhibitors & wetting agents. Highly effective on heating. Safe and easy handling and storage . Fast and effctive scale remover .
- Non-combustible solid
- Smoke from fires is irritating
- Not flammable. In case of fire use extinguishing media appropriate to surrounding conditions
- Prevent run off water from entering drains if possible
Scale and Rust Remover (Powder)
Application
Boilers, calorifiers, heat exchanges, diesel engine cooling system, condensers, evaporators & other type of equipment where rust & scale form.
Appearance Reddish / Yellowish / white – Powder ( without indicator )Density 1.2g/cm3 pH (10 wt %):1.1 Compatibility Metal Avoid aluminium, zinc, tin and their alloys. Avoid galvanised surfaces Rubber No known effect Rubber No known effect
Precautions

Recommended concentration: 3-8% by weight, depending on scale severity
Scale Condition Concentration Light scale (maintenance clean) 2-3% Moderate scale 4-5% Heavy scale (visible thick deposits) 6-8%For most cooling systems with routine mineral scale (calcium carbonate, etc.), 5% is a good general-purpose starting point - that's roughly 100 kg for 2,000 L.
A few important operating notes,:
- Circulation time: Typically 2-3 hours of circulation, checking pH periodically. Stop when pH stabilizes (acid is spent/scale dissolved) or after visual/lab confirmation.
-
Monitor progress: Check pH and iron/copper ion concentration in solution periodically (test strips or lab titration) rather than fixing a blind circulation time - stop as soon as scale is gone rather than over-circulating.
- Following the acid clean with a neutralization/passivation step - commonly a mild alkaline flush (e.g., sodium carbonate/soda ash, ~0.5–1%) to raise pH to neutral and form a protective passive layer on the iron/steel before refilling with treated water.
- Rinse thoroughly after neutralization before returning to normal operation.
