Product code RXSOL-37-1048-030
An organic acid liquid descaler designed to effectively remove calcium carbonate, mineral scale, rust and metal oxides from heat exchangers, piping and process equipment, with controlled compatibility for stainless steel, titanium and NBR gasket syst
ECO Safe Descaler Liquid is a concentrated, water-based acidic descaling formulation containing approximately 40% active organic acid blends. It is designed for the controlled removal of:
- Calcium carbonate scale
- Magnesium deposits
- Hard-water scale
- Mineral deposits
- Light iron oxide/rust deposits
- Metal oxides
- Inorganic deposits
- Carbonate-based deposits
The specialtity of RXSOL ECO Safe is that it acts both as an acid and as a chelating/sequestering agent, helping dissolve mineral deposits and keep dissolved metal ions in solution.
Unlike hydrochloric acid and other strong mineral acids, this special Descaler is a relatively weak organic acid and is commonly used where a more controlled acid-cleaning system is desired.
Can also used for stainless-steel cleaning and passivation; 304 and 316 stainless steels are generally considered suitable for normal acid handling applications.

Dosage
| Application | Product Concentration |
|---|---|
| Light scale | 5-10% |
| Moderate scale | 10-20% |
| Heavy scale | 20-30% |
| Severe deposits | Up to 100% product |
For most industrial cleaning operations, it is preferable to begin with a 10-20% product solution and increase concentration if required.
The optimum concentration depends on:
- Scale thickness
- Scale composition
- Temperature
- Circulation rate
- Cleaning time
- Equipment metallurgy
- Presence of oil/organic contamination
Best Practice to follow for CLEANING SCALE using RXSOL ECO Safe Descaler Liquid
Step 1: Pre-cleaning
Remove loose deposits and hydrocarbon/oily contamination where applicable.
For heavily oil-contaminated equipment, alkaline cleaning/degreasing should normally precede acid descaling.
Step 2: Prepare Cleaning Solution
Fill the system with water and add RXSOL Eco Safe Descaler Liquid.
Important: Add acid product gradually to water while circulating.
Do not add large quantities of water into concentrated acid in an uncontrolled manner.
Step 3: Circulation
Circulate the cleaning solution through the equipment.
Typical cleaning temperature:
20-60°C
NOTE: Higher temperatures can increase cleaning rate but may also increase corrosion and elastomer/material interaction. Therefore, temperature should be controlled according to the equipment metallurgy.
Step 4: Monitor Cleaning
Monitor following parameters while cleaning:
- pH
- Acid concentration
- Iron concentration
- Calcium concentration
- Appearance of solution
- Scale removal
- Corrosion condition
When the acid becomes substantially depleted, additional product may be required.
Step 5: Drain
Drain the spent cleaning solution according to the site's wastewater/environmental requirements.
Step 6: Water Rinse
Rinse thoroughly with clean water until the discharge is approximately neutral.
Step 7: Passivation / Neutralization
Where required, stainless-steel systems may receive an appropriate passivation treatment following cleaning.
