First gas station job. Im usually in the residential part of this profession. Was wondering if anyone could give me advice on chemical ratios and idea ways of billing.
Can you be more specific? I imagine you’re referring to degreasers and such for the oil. You mix stronger and stronger until it works. Look at https://www.pressurewasherky.us/ for good degreasers
With a gas station I’d be more worried about reclaim…
As mentioned you have to be more specific. Prices vary city to city and even gas station to gas station. I imagine most of it is concrete cleaning so just charge what you normally charge for concrete. You might need to come in a little lower though to win the bid.
