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.

This descaling liquid contains special quaternary corrosion inhibitors which prevent excessive corrosion in the systems provided other parameters are followed. RXSOL ECO Safe Descaler is not a normal descaling liquid: this corrosion inhibitor and other wetting agents provide essential features to this descaling liquid.

Material compatibility should always be established before cleaning mixed-metal systems.

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.

Cast Iron	Use only for very less time otherwise pitting may occur
Copper	Use only for very less time otherwise pitting may occur
Brass	Generally avoid
Bronze	Testing required
Aluminium	Avoid unless specifically validated
Aluminium alloys	Alloy-specific testing required
Galvanized Steel	Acid attacks zinc coating
Zinc	Rapid acid reaction possible
Titanium	Generally excellent
Hastelloy	Generally suitable
Nickel alloys	Alloy-specific confirmation recommended
PTFE	Generally suitable
PVDF	Generally suitable
PVC	Verify temperature
PP	Generally suitable
HDPE/PE	Generally suitable

A compatibility chart should not be interpreted as "ECO Safe Descaler can be left indefinitely in the equipment."

For example, stainless steels are generally very resistant to ECO Safe, but temperature and chloride contamination can change the corrosion risk. The British Stainless Steel Association specifically notes that chloride contamination can cause pitting and that higher temperatures may require more corrosion-resistant stainless grades.

ECO Safe Descaler Liquid is considered safe on elastomers like NBR , Buna-N. Note that elastomer contact time and temperature are exrtemely crucial to prevent swelling on gaskets.
