The key rule
Do not combine products even when each is sold for cleaning. Reactions may create irritating or toxic gases, splashes or surface damage.
Step-by-step process
- Identify the surface, soil and manufacturer limits.
- Prepare ventilation, gloves and separate tools.
- Spot-test and use the smallest effective amount.
- Remove residue, dry and assess before repeating.
Limitations
Unknown substances, strong fumes, health symptoms, electrical hazards, extensive mould or biological contamination require stopping and seeking appropriate help.
