Abstract: The present invention relates to cleaning compositions, in particular to cleaning compositions for use in heating, ventilation and air-conditioning (HVAC) installations. We describe an acidic cleaning composition concentrate comprising: at least one acid having a pKa1 of 4 or less, wherein the at least one acid is at least one organic acid and/or non-oxidising mineral acid; a rheology modifier; and a polar protic solvent. In some examples, compositions may also include at least one of one or more weak nitrogenous bases, one or more carboxylate salts and one or more one surfactants;

Abstract: A neutralizer, destainer/descaling, and passivating composition and methods of using the same on metal surfaces are disclosed. The compositions are particularly well suited for the treatment of health care surfaces and other hard surfaces in need of treatment. In particular, the neutralizer, destainer/descaling, and passivating composition is an acid-based composition for use in instrument reprocessing.
