Can I dilute and store a large volume of regular strength enzyme?

Absolutely! 

1. Pour the entire 8 oz into a 1 gallon jug

2. Fill it up with water (to dilute it properly)

3. Give it a shake and let it sit for an hour (it is for the water and concentrate to mix)

Now, you have a well mixed 1 gallon regular strength supply!

4.  (Optional) Pour it in a spray bottle to spray on a stain. Wait 10 minutes before starting the wash cycle.

*16 oz can make 2 gallons
