Stanrose® Liquid Descaler

A fully inhibited, fast acting descaler.

Common Name

Scale Remover - Liquid

Product Code


Features and Benefits

Add “Stanrose® Liquid Descaler” slowly, a few gallons at a time, to the tower to reduce tendency to foam.
Foaming indicates that descaler is dissolving the scale. If excessive foam occurs, use Defoamer.
Any method of descaling either boilers or towers will dissolve scale that may be plugging areas that are already leaking due to rust or other corrosion, therefore, no liability can be assumed.

Technical Properties

Contains a balanced ratio of acids and surfactants, making it a suitable descaler for boilers and water towers. It contains built-in pH indicator.
Contains acids. Do not use on aluminum, decorative metals, zinc, magnesium, galvanized or painted surfaces.
Spot test small area for sensitivity before use.

Recommended Uses

For Descaling Boilers and Water Towers

Method of Application

For Descaling Boilers :
For initial descaling, mix 1 part “Stanrose® Liquid Descaler” with 5 parts water in the system. Later cleaning may require less concentration. Isolate unit to be cleaned to protect valves and avoid possible contamination of rest of system. Fill boiler with “Stanrose® Liquid Descaler” and water at a 1:5 to 1:20 ratio. Heat the water to 60oC-80oC (140oF-190oF) and circulate for about 4 hours and then check the tubes. If descaling is not complete, refill the boiler with “Stanrose® Liquid Descaler” and water and repeat. Drain the boiler and flush with water pressure to remove all the scale and sludge. Drain and fill the boiler at least 3 times.
For Descaling Water Towers :
Shut tower down and use high pressure water to hose out mud, silt and slime. Isolate the unit to be descaled to protect valves and avoid possible contamination of the rest of system. Lower water level to just the amount required for circulation. Add “Stanrose® Liquid Descaler” to water in the tower at the ratio of 1 part in 5 parts of water. Add enough “Stanrose® Liquid Descaler” to maintain the pH from 1.5 to 2.5. Continue adding, as required, to maintain proper pH level for about 4 hours. The circulating solution should be yellow in color. If the solution while circulating turns blue, more “Stanrose® Liquid Descaler” needs to be added. Drain the system, flush and fill twice and check pH of water to be certain all “Stanrose® Liquid Descaler” has been removed.

Storage and Handling

Avoid contact with eyes and skin. In case of contact rinse with plenty of water. Wear suitable protective clothing, gloves and eye/face protection.
Keep away from heat, sparks and open flame. Ensure that the working area is well ventilated.
Store at moderate temperatures in dry, well-ventilated area.
