Beach-Salt Film & Siding Oxidation — Myrtle Beach Homes
Beach-Salt Film & Siding Oxidation — Myrtle Beach Homes — what this page covers
Salt air is an abrasive. The film it leaves on siding holds moisture against the surface, which accelerates oxidation and gives mildew a foothold. Regular soft washing removes the salt before it bonds; homes inside the first mile of the Grand Strand benefit most from an annual wash.
