When I get clothes used, I wash and use these. All odors and build ups are gone. First started using them to remove mineral build up in cloth diapers. So easy to use! Just pop in the washer after a wash cycle and do a rinse cycle after. No soaking required. Must use hot water as it states, otherwise it doesn't dissolve as it needs to.
I wanted to wash my whole laundry with them.
Overall these packets do a good job helping to give our diapers a boost in cleaning. I’m not sure I notice difference with cleaning off stains. It’s more about helping the diapers to smell better.
