If you're unfamiliar with how to clean fiberglass, it may surprise you to learn that it's a fairly easy task. With some white vinegar and a few basic cleaning tools, your fiberglass will be sparkling in no time.

Step 1 - Remove Dust from Your Fiberglass

Start this step by lightly dampening a nonabrasive washcloth and gently wiping the surface of the fiberglass using broad, circular motions. In addition to getting rid of dust, this should also successfully purge any minor dirt deposits. After removing as much dust and dirt as you can with your dampened cloth, you'll be ready to proceed with the cleaning process.

Step 2 - Apply Vinegar

Pour some white wine vinegar into an empty spray bottle and spraying it across the surface of your fiberglass. If you wish, you may dilute the vinegar with warm water.

Once your vinegar or vinegar-and-water solution has been applied, allow it to sit for several minutes, then use a soft sponge or nonabrasive cloth to begin wiping your fiberglass in a circular fashion. Due to fiberglass's delicate nature, try not to apply too much pressure when performing this step. After the fiberglass has been fully cleaned, rinse off your vinegar solution with a water-filled spray bottle or a dampened nonabrasive washcloth. If any stains or dirt deposits remain after this process has been carried out, you will need to proceed with the next step.

Step 3 - Apply Baking Soda

Baking soda can be an invaluable tool when it comes to cleaning fiberglass. If any areas of your fiberglass are still laden with filth, you'll need to sprinkle some baking soda onto the dirty areas. Next, give the baking soda a few minutes to set in, then spray some white wine vinegar onto it. This will subsequently create a fizzy reaction that will lift and loosen any caked-on dirt, enabling it to be effortlessly wiped away. For maximum effectiveness, allow the newly formed baking soda and vinegar solution to sit for at least 15 minutes. Once all the dirt and grime has been successfully lifted and wiped away, rinse your fiberglass with warm water.

If you don't have access to any additional white wine vinegar, baking soda can also be mixed with warm water to create a thick paste that has a similar effect to the above mentioned solution. However, because of vinegar's highly acidic nature, it is generally more effective at loosening stubborn stains than a baking soda and water paste.
