303 Multi-Surface Cleaner 16 oz is a liquid cleaner for spots and soil on compatible water-safe materials. This order supplies one 16 oz container for the cleaning task you select. Match manufacturer code 30445 and the exact package before ordering.

The manufacturer identifies water-safe fabrics, vinyl, rubber, plastics and selected metal surfaces among its applications. Its spot-cleaning process lifts soil such as coffee, oil, grease or ink and removes excess product with a damp cloth. This is a cleaning stage; it does not establish UV protection, restored fabric repellency, oxidation correction or disinfection. Check the actual material, coating, stitching and care instructions before applying it.

Compare the available single and case formats by storage needs and how the cleaner will be dispensed; a larger container is not evidence of a stronger formula. The 16 oz listing provides a smaller single container for storage and handling; compare its exact code with any proposed replacement. Wet the permitted spot, work with a suitable wet cloth or label-approved brush, lift loosened soil and excess cleaner with a damp cloth, and let the surface dry. Rinse the cloth in clean water as needed. No numeric dilution or universal working time is supplied; consult the fabric maker for mildew or special cleaning problems.

Compare Container Size, Case Quantity and Care Role

This listing supplies one 16 oz container. Compare it with the linked same-family package using the exact listed code, per-container contents, dispensing needs and full order quantity. A different pack size is a purchasing choice, not a permission to change the label’s cleaning strength or method.

Multi-Surface Cleaner belongs to the cleaning stage. A separate fabric water repellent, UV protectant or restoration product has its own role and requirements. Choose by the actual surface and soil first, then compare the related package; do not assume every similarly named 303 formula is interchangeable. Review the 303 Multi-Surface Cleaner - 16oz *Case of 6* MPN - 30445CASE as a separately sold option.
