What is the primary purpose of burnishing a VCT (vinyl composition tile) floor after stripping and recoating?
Answer: To create a high-gloss wet-look shine by friction-heating the finish
Burnishing uses high-speed friction to heat and harden the top finish coat, producing a high-gloss appearance.
When cleaning glass windows and mirrors, streaks are most commonly caused by:
Answer: Leaving cleaning solution residue due to insufficient wiping
Streaks form when cleaning solution dries on the glass before being fully removed, leaving residue behind.
A custodian needs to clean an elevator cab floor made of marble. Which product should be AVOIDED?
Answer: Acidic tile cleaner or vinegar-based solution
Acids etch and permanently damage marble and other natural stone surfaces, so only pH-neutral products should be used.
In high-traffic areas, how often should spot-mopping of spills be performed compared to scheduled cleaning?
Answer: Immediately as spills occur to prevent slip hazards
Immediate spot-mopping of spills prevents slip-and-fall accidents and complies with safety standards for hazard abatement.
What does MSDS/SDS stand for and why is it critical to custodial work?
Answer: Material Safety Data Sheet; provides chemical hazard and handling information
An SDS (Safety Data Sheet) contains essential information on chemical hazards, safe handling, PPE requirements, and emergency procedures.
When using a two-bucket mopping system, what does each bucket contain?
Answer: One bucket for cleaning solution, one for rinsing dirty mop heads
The two-bucket system separates clean solution from dirty rinse water, preventing reapplication of soiled water to floors.
Which technique should be used when dusting horizontal surfaces in an office to avoid scattering dust into the air?
Answer: Use a slightly dampened or treated cloth with gentle, controlled strokes
A lightly dampened or treated cloth traps and holds dust rather than dispersing it into the air where it settles elsewhere.
