Before a visit, identify floors, counters and furniture requiring specific care. Keep instructions available and point out existing damage.
Wood and wood-look floors
Identify whether the floor is wood, laminate, vinyl or another material. Appearance does not establish the care requirements.
Remove loose grit appropriately before damp cleaning. Follow the floor manufacturer’s directions; excess liquid can harm wood. Bona’s wood-floor guidance also recommends avoiding excessive liquid. Do not assume steam is permitted without the flooring manufacturer’s approval.
Natural stone
Know the stone type and whether it is sealed. The Natural Stone Institute notes that acids can etch calcareous stone and abrasives can scratch some surfaces.
A dull or etched area may be finish damage rather than dirt. Repeated scrubbing is not a substitute for assessment.
Tile, grout and surrounding finishes
Consider the entire area: grout, sealants, fixtures and adjacent stone. A product selected for tile can still affect those materials. Tell the cleaner about loose grout, damaged caulking or a leak.
Glass, appliances and furniture
Ask about protective films, coatings and manufacturer restrictions. Scraping glass is not automatically safe. Paint or adhesive removal should be discussed before treatment.
Use the instructions for each appliance or furniture finish. Do not apply a method solely because it worked on a different steel appliance, painted cabinet or tabletop.
When the material is unknown
Pause and identify it. Ask the supplier, installer or manufacturer for care instructions. A cleaner should not have to guess whether an aggressive product is acceptable.
Add restrictions to your cleaning brief. For specialist work, see upholstery cleaning and window cleaning.
