"I am confident in the integrity of Cotey Chemical Corp. and trust their products."
"We've recently constructed an 8" municipal well that produced 80 GPM - 500' depth. During the grouting, approximately 70 bags of cement ended up in the well and blocked all water from entering the well. We used Dry Acid Special three weeks after grouting and restored yield to 80 GPM. Valley Drilling Corporation of Virginia will be using Cotey Chemical products for all well cleaning."
"We've been using Cotey Chemical products since 1960 and have been very pleased."
"Cotey Chemicals work better in our area than any other brands we've tried. As far as we're concerned they are the best on the market."
"Cotey Chemical has been providing products and services to our company for the past eight years. As a result we have increased our services to our customers with excellent results and profits." Sergio A. Leon Zamudio Pozos Dinamicos, S.A. de C.V. Hermosillo, Sonora, Mexico
