I use Bio-Dry and secured 3 big garages in Atlanta that would not even think about paying normal pressure cleaning rates right now. We basically rented a scrubber and scrubbed the deck first. Let it dry for a day and then applied the Bio-Dry to the oil spots only. They were ecstatic and gave me two more garages right away. I would say it looked 75% as good as normal pressure washing at 1/3 of the cost. Sure I would have loved to pressure wash the whole thing but $30,000 was not in the budget (low occupancy) but they gladly paid $11,500 for the service.
As Scott said just another tool in the bag.

I truly understand about budgets. That is the one objective that everyone must overcome in their presentations. The difference in price, in your example, is about 40% cheaper than using a washer.
Let me say this, I have used a scrubber before at $600 a day plus fuel and pick up / delivery charges. They have there place. However, cleaning a parking garage, they don't even come close to the quality that our customers demand. At best, they help to remove the loose powder film that may be on the floor, but will achieve nothing about cleaning the deep ground in stuff. I have seen the scrubber clean AT BEST 5% of the filth. So when it comes to break dust, brake fluid, tranny oil, rubber, urine, pigeon feces, dirt, throw up, blood, the 50+ chemicals that any giving auto/ truck can deposit, this Bio- Dry will not remove all of it or even 20%. All that I can see is that it puts a band aid over the problem.
Any if it gets wet, as so may garages do in the winter, the run off of the hundreds of gallons of rain water will affect it.
These are the issues that I would tell my clients who may say, I like this company because they use this XYZ product and it is cheaper. Then I would show the documents that we have, saying just that, along with the EPA who discourages their use here in Contra Costa.
At best, this is for spot cleaning or a small gas pad spill, not for 400,000 sq ft. parking garage.
Thats my 2 cents...
