What material is recommended for cleaning smoke detectors?

Using a soft brush or vacuum attachment is the recommended material for cleaning smoke detectors because it effectively removes dust and debris that can accumulate on the detector's sensing chamber, which may hinder its performance. This method protects the delicate components of the smoke detector while ensuring that it remains free from contaminants that could affect its ability to detect smoke accurately.

A moist cloth might leave moisture behind on sensitive electrical components, which could potentially lead to malfunction or corrosion. Paper towels can be abrasive and may leave small fibers that could interfere with the detector's functions. Compressed air can dislodge particles but may also blow dust further into the device, rather than removing it completely, which can create issues with effectiveness over time. Therefore, the use of a soft brush or vacuum attachment is the most effective and safest method for maintaining smoke detectors.
