A Comprehensive Guide

Warning: Using liquid chlorine to remove mold and mildew stains from inflatable boat tubes can be effective but carries potential risks. Liquid chlorine is highly corrosive and can damage the adhesives used in boat construction if used excessively or improperly. This guide is provided as a last resort solution for stubborn stains, with the understanding that it may cause issues if not used with extreme caution. We strongly advise users to exercise extreme caution when using liquid chlorine and to follow all safety precautions provided. Additionally, it's important to note that this guide is intended to address existing stains and should be followed in conjunction with preventive measures, such as applying Marine Ceramics - Inflatable Boats & Vinyl ceramic coating, to prevent future staining.

Instructions:

Mold and mildew stains can be a persistent problem, especially for boat owners with inflatable boat tubes (dinghies/tenders), but with the right approach, they can often be effectively removed. It's crucial to address these stains before applying any protective ceramic coatings to ensure they don't become trapped under the coating and locked in forever. Here's a step-by-step guide to help you remove difficult mold and mildew stains from your boat tubes:

1. Surface Preparation:

• Before attempting to remove mold and mildew stains, it's essential to thoroughly clean the surface of your boat tubes to ensure that any existing contaminants, such as salt, dirt, and other debris, are removed. This step is crucial for effectively identifying and targeting the mold and mildew stains. We recommend using Marine Ceramics - Marine Foam Cannon Soap for this purpose. By thoroughly cleaning the surface, you can ensure that the mold and mildew stains are clearly visible, allowing for their effective removal without the risk of locking them in long term under any protective coatings.

2. Removing Mold and Mildew Stains from Inflatable Boat Tubes:

• Mold and mildew stains can be stubborn, but with the right approach, they can be effectively removed. We have found that applying liquid chlorine to the stained areas can be an effective solution. However, caution must be exercised as excessive use can harm the adhesives of your boat tubes. Follow these steps carefully to safely remove mold and mildew stains:

• Prepare the Liquid Chlorine:
• Pour liquid chlorine into a chemical-safe container.
• Apply the Liquid Chlorine:
• With a solvent-safe brush, dip the tips of the bristles into the liquid chlorine. Only a small amount is needed.
• On a DRY SURFACE, carefully apply the liquid chlorine to the mold and mildew stained areas on the tubes. Avoid applying it to the seams of the tubes, as this can weaken them and cause damage more quickly.
• Allow Drying:
• Allow the liquid chlorine to dry. Once dry, it should leave a salt or crystal-like look on the surface.
• Inspect and Repeat:
• Inspect the mold and mildew stains to see if they have become lighter in color or removed entirely.
• If the stains are still present, apply another coat of liquid chlorine over the dried crystals and repeat the process until you are satisfied.
• Wash Off Liquid Chlorine:
• After achieving the desired effects, it is crucial to completely wash off and remove the liquid chlorine from the surface. Do not leave it on the surface longer than a few hours before removing to prevent potential damage. 

3. Surface Cleaning:

• After removing the mold and mildew stains, it's essential to thoroughly clean the surface of your boat tubes before applying any protective coatings. Start by washing the boat or yacht with Marine Foam Cannon Soap, following the provided directions. This will help eliminate salt, minerals, dirt, and other debris from the surface. Ensure the surface is completely clean and dry before proceeding. 

4. Applying "Inflatable Boats & Vinyl" Ceramic Coating:

• Once the surface is clean and dry, apply Marine Ceramics - Inflatable Boats & Vinyl ceramic coating to the boat tubes. This premium ceramic coating will provide protection against UV damage, mold & mildew stains, scuffs, and marine growth. Follow the application instructions provided with the product carefully for best results.

By following these steps carefully, you can effectively remove mold and mildew stains from your inflatable boat tubes and prepare them for further maintenance, such as applying a ceramic coating to prevent future staining.
