Chewing gum forms a strong adhesive bond with concrete and asphalt that becomes harder and more permanent over time. Cold water pressure, even at high PSI, cannot break this molecular bond — it just flattens the gum or pushes it into the pores. A specialized gum dissolvent must be applied first to break the bond, followed by hot-water extraction to fully lift and remove the residue.

Not with proper technique. Some cheaper steam-only methods can leave a dark halo where the surrounding concrete is still dirty. Our process removes the gum completely, then cleans the surrounding area to match — delivering a uniform appearance across the full surface rather than a spotted or patchy result.

Yes. Gasoline and fuel spill staining is a hydrocarbon-based stain that requires specialized pre-treatment before pressure extraction. We treat these with appropriate hydrocarbon dissolvent agents — commonly needed at gas station forecourts, fleet vehicle parking areas, and generator pad surrounds. Results depend on stain age and concrete porosity.

Retail entrances and food court pedestrian areas with high foot traffic typically benefit from monthly or quarterly gum and grease treatment. Parking lots with regular vehicle use should be treated semi-annually for oil staining. We offer recurring maintenance plans that keep high-traffic areas consistently clean without the need for intensive periodic treatments.
