Heavy Stain Removal at a Bank Drive-Thru Lane

Drive-thru lanes take a beating. Cars idling, fluids dripping, dirt and grime grinding into the concrete day after day - it adds up fast. And once that buildup gets bad enough, the whole property starts to look neglected no matter how clean the inside is.

Here's what we were working with on this one: heavy dark staining across the concrete curb and surrounding surface right next to the ATM area. The kind of buildup that doesn't budge with a standard rinse. It takes the right chemical application paired with the right pressure to actually break it down and pull it out of the surface.

That's exactly the process we used here. We pre-treat with chemicals designed to cut through that type of grime at the surface level, let it do its work, and then hit it with pressure to flush everything out. No shortcuts. The foam you can see mid-clean is that chemistry actively working - lifting the contaminants so the pressure wash can do its job properly.

The difference between a clean that looks decent and one that actually gets the surface back to where it should be comes down to that chemical step. Pressure alone just pushes dirty water around. The combination is what gets real results on commercial concrete like this.

For any business running a drive-thru or high-traffic lane, this kind of buildup is almost inevitable. The good news is it's completely fixable. Our commercial pressure washing process is built specifically for surfaces like this - and the results speak for themselves.
