ScaleFree™
Descaling Compound is an acid-based descaler
combined with a proprietary chelating agent that is effective in dissolving and removing
carbonate, lime-scale and iron scale build-up caused by hard water. ScaleFree efficiently and
effectively removes lime-scale build-up from combi ovens.
ScaleFree™
is a non-hazardous, Biodegradable Citrus Based Powder that when mixed with
water becomes a powerful lime-scale remover.
