In this review the 303 Multi-Surface Cleaner 1 gallon refill is judged for owners of boats, RVs, patio furniture and vehicles who want a single cleaner that handles multiple water safe surfaces. The bottom line: it is a practical, concentrated workhorse that removes stubborn spots like coffee, oil and ink while rinsing residue free, making it a strong choice for anyone who needs a gallon-sized cleaner for regular maintenance and larger projects.

Key Features

• All-purpose cleaning: Cleans and brightens a wide range of water safe surfaces, from vinyl and upholstery to plastic and metal, so one bottle covers many tasks.
• Residue-free finish: Formulated to rinse and dry without leaving films or sticky buildup, keeping surfaces ready for use or protection treatments.
• Manufacturer recommended: Endorsed by a leading outdoor fabric maker for use on outdoor fabrics, which gives confidence for cushions and awnings.
• Gallon refill size: The large container is convenient for larger jobs and frequent use, reducing the need to restock small bottles.
• Easy application: Spray, agitate with a soft brush if needed, then wipe or rinse for quick cleanup of dirt and common stains.

Who It's For

The cleaner suits boat and RV owners, patio furniture caretakers, car interior detailers and anyone with vinyl or fabric items exposed to regular dirt and stains.
