All of the different cleaning solutions (All-Purpose, Bathroom, Streak-Free, Foaming Wash and Laundry) use the same Concentrate, but each bottle has a different ratio of concentrate to water. Fill lines on the bottle labels make it easy to create the different solutions.
For example, our Bathroom solution uses twice as much Concentrate as the All-Purpose solution and the Streak-Free solution uses just a single drop of Concentrate.
That's it! The cleaning bottles are refillable over and over again.
