Checklist

Use one cleaning product as directed instead of combining them

More products can create a different hazard, not a stronger clean.

When it fits

  • You are preparing to clean or disinfect a surface.

When to avoid it

  • Do not experiment to see whether a mixture produces fumes. If an exposure occurs, move away from the hazard and contact local poison or emergency services for specific instructions.

Checklist

  • Choose a suitable product and read its instructions.
  • Keep other cleaning chemicals out of the process; do not improvise mixtures.
  • Use the ventilation and protective measures the label requires.

Why it matters

Read the current product label and use it only as directed. Never mix bleach or disinfectants with other cleaners. Keep the space ventilated and follow the specified protection and surface instructions. A familiar brand name does not replace checking the formulation and label.

An example

A cleaner does not pour a second product into a partly filled bottle to improve the first one.

Check your result

The task follows one understood product instruction without an unreviewed chemical combination.

Keep this limit in mind

  • Do not experiment to see whether a mixture produces fumes. If an exposure occurs, move away from the hazard and contact local poison or emergency services for specific instructions.
