Hello all, I am new to the business and would like to ask some questions. I will start off by washing parking lots at parts stores with a very heavy amount of oil stains. What type of cleaner, what to mix with and how much, and do you guys order online or buy locally? I have been reading for about a week and using the search feature and have learned a great deal already but am getting a little overwhealmed by all of the different types of chems and mixtures. If some of you guy's could help me I would really appreciate it. I live in Mississippi and my name is Chris. I look forward to hearing from you guy's.
