What is the table’s resistance to damage from outdoor de-icing chemicals?

When winter arrives, de-icing chemicals like rock salt, calcium chloride, and magnesium chloride are essential for safety but can be harsh on outdoor furniture. A common question among homeowners is: What is the table’s resistance to damage from these agents? The answer depends primarily on the material.

High-quality aluminum tables, especially those with a powder-coated finish, offer excellent resistance. The coating acts as a barrier, preventing the corrosive chemicals from reaching the metal beneath. Similarly, tables made from durable plastics or composite lumber are largely non-reactive and withstand salt exposure well, though they may stain over time.

Natural materials like untreated wood are highly vulnerable. Salt absorbs moisture, leading to wood rot, warping, and accelerated degradation. Cast iron, unless impeccably maintained with a thick, intact sealant, is prone to rust when exposed to corrosive salts.

The level of resistance is also defined by construction and maintenance. Tight, waterproof seals where legs meet the tabletop prevent chemical seepage. Proactive care—such as applying protective sealants to wood or metal, and promptly rinsing off any salt residue with water—dramatically enhances any table's longevity. Ultimately, choosing a material engineered for wet environments and committing to simple seasonal maintenance are the keys to ensuring your outdoor table survives winter's harsh chemical assault unscathed.
