Careclean HD Descalex L

Careclean HD Descalex L is an inhibited hydrochloric acid based descaler and rust remover. Careclean HD Descalex L is used for acid cleaning of boilers, condensers, diesel cooling water systems, evaporators, Butterworth heaters, pipe systems etc.

• Removes heavy deposits consisting water scale and iron oxides
• Very effective without heat
• Inhibited to protect cleaned surfaces from acidic attack
• Can be used on most common ferro, titanium and copper alloys
• Effective lavatory system cleaner

• Cleaning and scale removal from the sea water side of box coolers
• Scale and rust removal from boilers, condensers, evaporators, heat exchangers, diesel cooling water systems, etc

• We recommend that a preliminary test is carried out on samples of the original scale deposits in order to select the most suitable acid cleaner and optimize concentration and temperature conditions.
• When a boiler is soiled with light oil deposits or if silicates and/or calcium sulphates are present, boiling out with Careclean Alkaline Extra is recommended.
• If heavy mineral oil deposits are present in a boiler or cooling system, a preliminary treatment with an emulsifying cleaner, like Careclean Degreaser GP is recommended.

Before cleaning with Careclean HD Descalex L solution, we recommend to thoroughly rinse with water; this will partly or completely remove loose sludge, scale, etc. Depending on the nature of the scale and degree of contamination, it is recommend to use a cleaning solution with a concentration of 10 - 20 % Careclean HD Descalex L. Solutions of Careclean F Descalex L are normally used cold. In case Careclean HD Descalex L is used at higher temperatures, extra inhibitor is required.

During the cleaning process, inflammable and/or toxic gases are possibly be formed, therefore adequate ventilation must be provided. Avoid open fire. The length of the cleaning operation depends on the thickness and type of deposit and also on the product concentration. Generally speaking this period will be within 24 hours.

After cleaning, drain off the acid solution. Rinse the system with fresh water until a neutral pH is reached (use pH paper or a pH meter).

Collected acidic solution after cleaning can be neutralized with Careclean Alkaline Extra or Caretreat Neutralizing Liquid.

Marine Care provides a portable circulating pump and tank systems ideal for this product. Please refer to the Marine Care equipment information sheet.

Fill a plastic or plastic lined bath with a 20-30 % solution of Careclean HD Descalex L in water. Careclean HD Descalex L is used at ambient temperature. Introduce the components to be cleaned into the bath and let them soak for a maximum of 24 hours, depending on the degree of scaling. Remove the components from the bath and rinse them with a powerful water jet.

Suitable for most common ferro, titanium and copper alloys (metals), except zinc, aluminum, galvanized materials, cast iron and stainless steel.
