    303 RV Wash & Seal 30240 combines concentrated exterior washing with a built-in sealant. Mariners Warehouse SKU 99441 supplies one 128 oz container for RV maintenance. Choose it for routine dirt removal and a gloss-supporting wash stage rather than localized stain correction.

    The pH-neutral, high-foam formula is designed to preserve existing wax and coatings during washing. Its hydrophilic action encourages water sheeting, helping reduce spotting during drying. Actual results depend on water, finish condition and technique; confirm the RV exterior and any coating-specific requirements before use.

    For the bucket method, add 1 oz to 5 gallons of clean water. Gently wash with a suitable mitt or cleaning tool, rinse the entire RV thoroughly and dry immediately with a clean, soft towel for best results. Keep separate tools ready and follow current container guidance for any other approved equipment method.

    BOAT & RV WASH GUIDE

    Plan Your 303 RV Wash & Seal Wash

    Match your surface, measure the formula’s own dose and finish the correct wash procedure. Package quantity affects supply, not dilution.

    1. Confirm the Formula

      Match 30240 and distinguish this wash from similar names. Concentrated RV exterior washing with added sealant care.

    2. Check the Surface

      Confirm the RV exterior finish and any coating requirements. Check rubber roofs, matte finishes and walking surfaces separately instead of treating general exterior wording as approval.

    3. Check the Product Dose

      Use 1 ounce of product with 5 gallons of clean water, as specified by current manufacturer directions.

    4. Prepare the Wash Tools

      Use clean tools that suit the material and the exact product method. Keep separate formulas and working mixtures identified.

    5. Wash and Remove Residue

      Gently wash with a suitable mitt or cleaning tool, rinse the entire RV thoroughly and dry immediately with a clean soft towel for best results.

    6. Inspect Before Further Care

      Review the clean finish. Identify any remaining staining or oxidation and follow the finish maker’s protection routine.

    Exterior Wash-and-Seal or Localized Streak Removal?

    303 RV Wash & Seal is intended for the overall exterior wash stage, while 303 Black Streak Remover addresses localized runoff marks. A concentrated shampoo and a spot cleaner are different products with different preparation and removal requirements.

    Choose the measured wash when routine exterior dirt is the main task. Assess isolated black streaks separately and follow the selected spot cleaner’s instructions if needed. The added sealant in a wash does not establish a fixed protection interval or remove the need for finish-specific care. Review the 303 Black Streak Remover - 32oz MPN - 30243 as a separately sold option.
