What common household items are known to cause heat exchanger and vent system corrosion in an induced draft non-condensing furnace?

The correct choice highlights the significance of household chemicals in causing corrosion within the heat exchanger and vent systems of an induced draft non-condensing furnace. Household chemicals often contain corrosive substances that can emit vapors or residues. When these materials are introduced into the furnace's environment, they can settle in the heat exchanger and venting systems.

These chemicals, such as those found in certain cleaning agents, adhesives, and solvents, can react negatively with the metal components, leading to oxidation and degradation over time. This process compromises the integrity of the furnace, potentially resulting in inefficient operation or severe damage.

While other options, like cleaning products, cooking oils, and personal care products, can certainly affect indoor air quality or contribute to other issues within a home, it is the specific nature of household chemicals that makes them particularly prone to causing systemic corrosion in the furnace components. They often have properties and residues that are more aggressive in reacting with metal than the other categories listed.
