Indoor use Reviewed by Surendra.messages on 08 Apr 2021

We use this product primarily in our home. Adding to water for indoor plants seems to keep them healthier. We also spray a little into rooms to improve the bacterial quality and use it to wipe down surfaces as well. For all of these purposes, we dilute the concentrate 1:20.
