ProtoxHysan can be used anywhere, both indoors and outdoors.
As the active ingredient (chlorine dioxide) in ProtoxHysan leaves little salt and water on your surfaces, you can safely use the product for your entire mould removal. Many other mould remedies often contain active ingredients that bind strongly to your surfaces and therefore remain in your indoor environment.
Odour
Protox Hysan contains a small amount of alcohol (<1%), the same alcohol you know from cleaning agents such as glass and window cleaner. The alcohol has the same characteristic odour as glass and window cleaner, but disappears quickly when aired out after use.
