This is a food grade vinegar. Vinegar is highly concentrated acetic acid that growers find useful for adjusting pH in spray solutions and to clean drip irrigation lines.
To dissolve lime deposits in drip systems, best results are obtained by ending the irrigation cycle with a 2-5% concentration and flushing no less than 48 hours after treatment.
Utilize a titration test to determine the rate of application necessary to achieve the ph level desired.
