These pH strips are just a fun and simple way to test your products pH level. This small booklet (within your hand's palm size) contains 80 sheets.
1= Most acidic (red)
14 = Most alkaline (purple)
1. Open booklet and pull just ONE strip for each item you're testing.
2. Pour a little of the substance that you are testing onto the strip. Place strip in a dry area. We recommend placing the strip to dry on top of a paper towel as the strip color will transfer onto the surface.
3. Wait less than 10 seconds and the color of the strip should change . You can then match this color to the pH color in the booklet.
Note: The information on the back of the booklet comes in Chinese but we have translated the instructions for your ease and use.
