303 Automobile Tonneau Cover & Convertible Top Cleaner 30571CASE supplies six separate 16 oz spray bottles for permitted fabric/vinyl top and cover cleaning. Mariners Warehouse SKU 79939 is the full six-bottle case. Each bottle remains the underlying 30571 cleaner with its own wet-surface application and rinse method.

The cleaner lifts appropriate dirt, stains and environmental grime, with manufacturer-described residue-free rinsing under correct use. Cleaning prepares the surface for a separately selected protective treatment; it does not itself establish renewed fabric water repellency, UV protection or repair of torn fabric, seams and coatings. Identify fabric versus vinyl before deciding on follow-up care.

Rinse thoroughly to remove loose soil, then apply cleaner while the surface remains wet. Agitate lightly with a damp suitable sponge, towel or top-cleaning brush and rinse fully with clean water before the surface dries. For tougher stains, manufacturer guidance allows a 10–20-minute work period before gentle scrubbing and rinsing, subject to the exact label and conditions; never let the cleaner dry in place. Complete drying as the material requires before applying a separate approved protectant.

Top Cleaner or Fabric Guard?

30571 cleans appropriate fabric and vinyl tops through a wet-surface, rinse-off process. Fabric Guard is a separate water-repellent treatment for its own approved clean, fully dry fabrics. Cleaning and protective treatment are different stages with different working conditions.

This case supplies six separate 16 oz cleaner bottles. The single 30571 listing is a separate purchase for a smaller supply. Neither includes a fabric repellent or vinyl protectant, so select protection independently after correct cleaning, rinsing and drying. Review the 303 Automobile Tonneau Cover & Convertible Top Cleaner - 16oz MPN - 30571 as a separately sold option.
