Application and Dosage of Fernox Limescale Remover
Fernox Limescale RemoverDS-3 should first be dissolved in hot water at the maximum concentration of 1 kg per 10 litres of water (10%) with a minimum in-use concentration of 250g per 10 litres of water (2.5%). Hot water will accelerate de-scaling but do not exceed 80°C. The de-scaling process will release carbon dioxide gas (CO-2), which can cause foaming. Hence, space should be allowed for this before commencing work. A colour change from yellow, through green, to blue indicates the de-scaling power is exhausted. However, the major part of the solution’s effort is expended when green is reached and if cold the final change to blue can take a long time. When de-scaling is complete, drain and rinse several times until no traces or odours remain. DS-3 can be neutralised with Fernox System Neutraliser.
Fernox DS-3 contains Sulphamic acid with inhibitors, indicators and non-foaming surfactants.
pH: 2.0 at 1% w/w in water
