Descaling agents usually contain an [[acid]] as the [[active ingredient]], e.g. [[acetic acid]], [[lactic acid]], [[citric acid]], [[phosphoric acid]], [[hydrochloric acid]], or [[sulfamic acid]]. Descalers do not necessarily need to be acidic (although many are). Often the mechanism of descaling is done via [[chelation]]. Descalants of this sort can be the most powerful. [[Phosphonate]]s in particular are well known theshold effect scale inhibitors. == See also == * [[Water softener]] * [[Magnetic water treatment]] {{chem-stub}} [[Category:Cleaning products]] [[Category:Water]] == External links == ==References== [[zh:除垢剂]]
