303 Automotive Leather 3-In-1 Complete Care 30218CASE combines cleaning, conditioning and UV protective care for suitable finished leather and vinyl. Mariners Warehouse SKU 79936 supplies six separate 16 oz spray bottles. The full case contains six individual bottles, rather than one larger container.

The formula addresses surface dirt and grime and helps repel dust, lint and stains, while its conditioning and UV contribution support the material’s appearance. Check the actual finish and upholstery care instructions. Do not use on unfinished leather such as suede, fabrics or flooring; conditioning does not repair tears, cracks or worn surface coatings.

Test a small, hidden area for colorfastness and stop if discoloration occurs. Spray the permitted surface and wipe dry with a suitable clean microfiber towel or applicator. Work soiled areas as directed before removal and use a suitable upholstery brush only where the material permits. Remove any excess with a damp towel and immediately wipe dry, following the full bottle instructions.

Leather 3-in-1 Care or General Protectant?

Leather 3-in-1 Complete Care combines cleaning, conditioning and UV care for suitable finished leather and vinyl. Aerospace Protectant serves a protective finishing role on its own clean, dry approved materials. Choose the actual task and upholstery finish before comparing bottle size.

The single 30218 bottle and 30218CASE six-bottle purchase are separate supply options. Neither includes towels or repair materials, and neither package approves suede, fabric or flooring. More bottles do not increase formula strength or repair damaged upholstery. Review the 303 Automotive Leather 3-In-1 Complete Care - 16oz MPN - 30218 as a separately sold option.
