Best Cleaners For Sunbrella Boat Covers: Effective Options

Sunbrella fabrics are designed to be durable, fade-resistant, and easy to maintain. They are a popular choice for marine applications due to their ability to withstand the harsh conditions of life on the water. While Sunbrella fabrics are known for their quality and longevity, proper cleaning and maintenance are essential to ensure their longevity and aesthetic appeal. This is especially true for Sunbrella boat covers, which are constantly exposed to the elements and require regular care to prevent dirt and stains from setting in. This article will explore the best cleaning methods and products for Sunbrella boat covers, ensuring they remain in top condition for years to come.

Regular monthly cleaning

Sunbrella fabrics are designed to be durable and long-lasting, but regular care and maintenance are essential to keeping them in good condition. Here is a detailed guide for the regular monthly cleaning of Sunbrella boat covers:

Brush Off Dirt and Debris:

Start by brushing off any loose dirt and debris from the fabric. This step is crucial to prevent dirt from becoming deeply embedded in the fabric, making it easier to clean and maintain.

Hose Down with Clean Water:

Use a hose to rinse the fabric with clean water. Avoid using a pressure or power washer, as it may damage the fabric. This monthly rinsing helps to prevent the need for deep cleaning and keeps your boat cover looking good.

Prepare a Mild Cleaning Solution:

Create a mild cleaning solution by mixing a mild soap, such as Woolite® or Dawn® dishwashing liquid, with clean water. You can also use a specialised fabric cleaner like Sunbrella Clean™ Multi-Purpose Fabric Cleaner or 303® Multi-Surface Cleaner. These products are designed to effectively clean Sunbrella fabrics.

Apply the Cleaning Solution:

Use a soft-bristle brush to apply the cleaning solution to the fabric. Work the solution into the fabric gently, allowing it to soak for a few minutes. Ensure you cover the entire surface area, cleaning from seam to seam, to avoid water rings and discolouration.

Rinse and Remove Soap Residue:

Thoroughly rinse the fabric with clean water to remove all soap residue. It is important to ensure that no soap residue remains on the fabric, as it can affect the performance and appearance of the Sunbrella fabric.

Allow the Fabric to Air Dry:

After rinsing, let the fabric air dry. Sunbrella fabrics are designed to air dry quickly, and machine drying is not necessary. Avoid using a dryer or applying heat directly to the fabric, as it may cause damage.

By following these steps on a monthly basis, you can effectively clean your Sunbrella boat cover, maintaining its durability and appearance. Remember to be gentle and use soft tools to avoid any potential damage to the fabric during the cleaning process.

Removing mildew and stains

Sunbrella fabrics are mildew-resistant, but mildew may grow on dirt and other foreign substances that are not removed from the fabric. To remove mildew and tough stains, follow these steps:

• Prepare a cleaning solution of 1 cup of bleach and 1/4 cup of mild soap per gallon of water.
• Soak a sponge or clean towel in the solution and blot the stain or use a soft-bristle brush to loosen it.
• Rinse the fabric thoroughly with clean water to remove all soap and bleach residue.
• Allow the fabric to air dry.

For severe mould or mildew growth, you can increase the quantity of bleach used. It is recommended to use Sunbrella Clean™ Multi-Purpose Fabric Cleaner followed by a diluted bleach solution.

To prevent mildew and stains, it is important to clean your Sunbrella fabric regularly. Brush off any loose dirt and address spills as soon as they occur. Blot liquid spills with a clean, dry cloth and apply an absorbent such as corn starch to oil-based spills before removing with a straight edge.

Monthly rinsing with a hose or bucket of clean water can also help to prevent the need for deep cleaning.

Using bleach

Sunbrella fabrics are made to last through years of use and exposure to the elements. Regular care and maintenance are important to ensure long-lasting performance.

Sunbrella fabrics are mildew-resistant, but mildew may grow on dirt and other foreign substances that are not removed from the fabric. For heavy cleaning of stubborn stains and mildew, a diluted bleach solution can be used. Prepare a solution of one cup of bleach and one-fourth cup of mild soap per gallon of clean water. Allow the mixture to soak into the fabric for up to 15 minutes. It is important to note that this step should be avoided when cleaning the coated side (back side) of Sunbrella Plus, Supreme, or Clarity. After soaking, blot the stain with a sponge or clean towel, or use a very soft bristle brush. Rinse the fabric thoroughly to remove all soap residue. Finally, allow the fabric to air dry.

For severe mould or mildew growth, the quantity of bleach used can be increased. It is recommended to use a diluted bleach solution after applying a multi-purpose fabric cleaner. Always wear gloves and work in a well-ventilated area when using bleach.

When using a bleach solution, it is important to protect the surrounding area as bleach may discolour non-Sunbrella fabrics. Additionally, use caution when cleaning the coated (underside) of certain Sunbrella fabrics, as the coated side should only be sprayed with the bleach solution and then thoroughly rinsed.

The use of bleach can impact the deterioration of sewing thread and other non-Sunbrella components. Bleach can also have harmful effects on the natural environment, so it is not advised to use bleach if you are near a body of water or another environment that could be affected. Always rinse Sunbrella thoroughly to completely remove bleach.

Machine washing

Preparation:

Before machine washing, it is crucial to identify the type of Sunbrella fabric. Sunbrella upholstery fabrics can be machine washed, but Sunbrella marine and awning fabrics are not suitable for machine washing. Ensure that the fabric cover can be removed from the upholstered piece for machine washing. Close any zippers on the fabric before washing.

Washing Instructions:

Use the delicate cycle on your washing machine and set the temperature to cold. Avoid using hot water as it may damage the fabric. Choose a mild laundry detergent and use a normal amount based on the size of the wash load. If you want to remove mould and mildew, add 1 cup of bleach to the washing machine. Do not use fabric softener, as it may affect the water repellency of the Sunbrella fabric.

Drying:

Sunbrella fabrics should never be machine dried. Always allow the fabric to air dry naturally. Avoid hanging the fabric in direct sunlight, as it may cause fading or discolouration.

Frequency:

Sunbrella fabrics are known for their durability and ease of maintenance. In most environments, a thorough cleaning is required every two to three years. However, regular monthly rinsing or hosing can help prevent dirt build-up and reduce the need for frequent vigorous cleaning.

Stain and Mildew Removal:

For stubborn stains or mildew, a heavy cleaning process is recommended. Prepare a solution of 1 cup of bleach and 1/4 cup of mild soap per gallon of water. Apply this solution to the entire area and allow it to soak into the fabric for about 15 minutes. Then, use a sponge, clean towel, or very soft bristle brush to remove the stain. Rinse thoroughly to remove all soap residue, and allow the fabric to air dry.

Retreatment:

After cleaning, the water repellency of Sunbrella fabric may need to be replenished. Sunbrella recommends using 303® Fabric Guard for restoring water repellency. Apply two light coats of the product in a well-ventilated area, following the instructions on the container.

Professional cleaning services

Sunbrella fabrics are designed to be long-lasting and easy to maintain. However, for thorough cleaning, you may opt for professional cleaning services. Here are some detailed instructions and considerations for professional cleaning services:

• Experience and Knowledge: When evaluating professional cleaning firms, inquire about their experience with Sunbrella fabrics. Ensure they understand the specific cleaning and retreatment requirements of these materials.
• Spills and Stains: While Sunbrella fabric offers excellent stain protection, full removal is not guaranteed if spills are not addressed promptly. Professional cleaners should be equipped to handle various types of spills and stains, including oil-based stains, mildew, and mould.
• Cleaning Solutions: Professional cleaners should be well-versed in the appropriate cleaning solutions for Sunbrella fabrics. This includes the use of mild soap and water, and, if needed, diluted bleach solutions for heavy-duty cleaning. They should also be aware of any specific requirements for Sunbrella fabric types, such as Sunbrella Plus, Supreme, or Clarity.
• Retreatment: After thorough cleanings, Sunbrella fabrics may require retreatment with an appropriate agent. Professional cleaners should be knowledgeable about the retreatment process and recommend suitable products like Sunbrella Restore™ Fabric Protector & Repellent or 303® Fabric Guard™.
• Drying and Ironing: Sunbrella fabrics should be allowed to air dry. Professional cleaners should avoid machine drying. For wrinkles, a synthetic iron setting can be used, but testing on a small area first is recommended due to varying iron temperatures.
• Environmental Considerations: When using bleach for cleaning, it is essential to consider the environmental impact. Bleach can have harmful effects on the natural environment, especially if used near bodies of water. Professional cleaners should be mindful of this and take the necessary precautions.
• Maintenance: Regular maintenance and cleaning of Sunbrella boat covers will help extend their lifespan and maintain their appearance. Professional cleaners can advise on proper care routines, such as monthly hosing or brushing off loose dirt to prevent dirt buildup.
