Substrate Identification
Determination of the actual material and finish beneath contamination, including coatings, films, dyes, repairs, textured plastics, leather, fabric, and display layers.
- Appearance can mislead
- Hidden tests reveal sensitivity
- Repairs may change tolerance
Soil Chemistry
The chemical and physical character of contamination, such as mineral, metallic, petroleum, organic, protein, particulate, adhesive, or product residue.
- Different soils need different mechanisms
- Mixtures complicate removal
- Unknown soil favors conservative testing
Dwell Window
The allowed period a product remains active and wet before agitation, removal, rinsing, or damage risk changes.
- Temperature changes timing
- Porous materials absorb product
- Drying can concentrate residues
Machine Interface
The dimensional and operating relationship among polisher, backing plate, pad, spindle, orbit, speed range, power source, and guarding.
- Diameter affects edge exposure
- Motion changes heat
- Ratings must be compatible
Coverage Quantity
The usable amount of product and clean media required for surface area, soil severity, repeated passes, replacement, and waste.
- Sample sizes may be insufficient
- Large vehicles consume more
- Contaminated towels leave capacity
Stage Compatibility
The ability of one completed step to leave a surface condition accepted by the next product, abrasive, coating, adhesive, or inspection gate.
- Oils can obstruct bonding
- Residues can change cut
- Water can delay cure
