Routine soil
Dust, foot traffic, airborne soil, and ordinary outdoor buildup.
Typical potentialStrong response
Field aimUniform surface clean
Reference ST / Concrete conditions
Some marks sit on concrete. Others live in it.
A stain can be surface residue, absorbed material, mineral reaction, coating failure, or physical damage. Naming the condition correctly is the first step toward a useful expectation.
01
Typical response index
A field estimate—not a removal guarantee.
The bands below show relative cleaning potential under ordinary conditions. Age, depth, concrete composition, coating, prior treatments, and heat can all change the result.
Monsoon residue
Silt, organic material, wet dust, and debris left to dry in place.
Typical potentialOften improves
Field aimLift residue + even tone
Tire transfer
Rubber compounds and heat pressed against the concrete surface.
Typical potentialOften improves
Field aimTargeted treatment
Fresh oil
Automotive fluid that has not had years to migrate into the slab.
Typical potentialTreatment matters
Field aimAbsorb + reduce penetration
Old oil shadow
Hydrocarbon residue absorbed below the visible surface.
Typical potentialShadow may remain
Field aimDegrease + lighten
Rust + minerals
Metal contact, irrigation, hard water, or material reaction.
Typical potentialTest required
Field aimMaterial-specific spot test
Paint + adhesive
A bonded coating rather than ordinary surface soil.
Typical potentialSeparate assessment
Field aimDifferent process or trade
Surface damage
Etching, spalling, battery acid, failed coating, or concrete wear.
Typical potentialNot a stain
Field aimDocument—not conceal
Field truth / 01
Pressure is not chemistry.
Increasing pressure can damage the surface without solving a stain that needs time, absorption, degreasing, or a material-specific treatment.
Field truth / 02
Clean is not repaired.
When dirt is removed, old etching, color variation, spalling, wand marks, and failed coatings can become more visible—not less.
Field truth / 03
Improvement is still a result.
A responsible scope can target substantial improvement while documenting why complete removal is unlikely.
02
Targeted treatment
Treatment is added by condition—not by surprise.
A small targeted area begins at $39 when added to a qualifying cleaning scope. The written scope identifies the stain, the planned treatment, and the possibility that a visible shadow will remain.
