Loose dirt is one job
Compressed air, brushing, and vacuuming move loose dirt from seams, carpet, mats, and tight spaces. That is different from treating material inside the fabric.
Embedded material needs more work
Shampoo, agitation, steam, and extraction are used according to the fabric and condition. The goal is to lift what a surface pass leaves behind.
- Seat and carpet stains
- Food or drink spills
- Ground-in footwell dirt
- Fabric that needs extraction
Describe the source
Say what spilled, how long it has been there, and whether the odor or stain returned after an earlier cleaning. That helps Rod Shine understand where the work may need to go deeper.
