An oxidizer is a substance that can promote oxidation. Product hazards and suitable uses depend on the specific chemical and formulation.
What this means at your property
Some treatment products rely on oxidation, but the same broad chemistry term covers substances with different handling requirements. A proposal should name the product and intended surface rather than imply that the category itself establishes safe or effective use.
What information should accompany a proposed product?
Ask for the label and safety data sheet, including compatibility and occupancy restrictions. Do not combine chemicals or use a product outside its instructions. Keep the product record with the work performed.
