The next day the product was used in our customer’s home. Upon arrival the technicians sprayed down the oil stained garage floor and structural lumber and went to lunch. When they came back about 40 minutes later the odor was gone….. In closing I would say that I was very happy with the product we used and also with the service I received from Satya Ganti, he answered all my questions and promptly returned my phone calls. He even called me after the job was done to follow up.
