What is the expected outcome when using defog on a canopy with ice?

When using defog on a canopy that has ice, the expected outcome is that it may not clear the canopy. This is due to the nature of defogging agents and the underlying conditions. Defog products are designed to prevent or reduce fogging by creating a barrier that inhibits condensation, but when ice is present, the effectiveness may be compromised.

Defog solutions are not formulated to dissolve or remove ice, which requires a different approach or treatment. In cold temperatures, the ice can remain stubbornly attached, and the aerosol or chemical composition of a defog might not sufficiently address the solid state of the ice. Therefore, while it may assist in clearing some fog or minor condensation, it does not guarantee complete clearing of the ice from the canopy.
