Understanding the Enemy: Mold, Mildew, and Algae

Before diving into cleaning methods, it’s essential to understand what causes those pesky black spots. The primary culprits are usually mold, mildew, and sometimes even algae.

Mold and mildew thrive in warm, damp environments, making pool floats the perfect breeding ground. These fungi feed on organic matter, such as dirt, sunscreen residue, and even the plasticizers in the float material itself. As they grow, they produce dark-colored spores that manifest as black spots.

Algae, while less common, can also contribute to the problem. Certain types of algae, particularly black algae, can cling to surfaces and form dark patches. While black algae typically prefer pool surfaces, they can sometimes find their way onto pool floats, especially those that are frequently left in the water.

Distinguishing between these can be tricky, but generally, mold and mildew tend to be slightly fuzzy or raised, while algae are usually flatter and slimy. Regardless of the specific organism, the cleaning methods outlined below will effectively tackle all three. Regular cleaning and proper storage are key to preventing their growth.

What causes black spots to appear on pool floats?

Black spots on pool floats are typically caused by mold and mildew growth. These fungi thrive in warm, moist environments, making pool floats an ideal breeding ground, especially when left damp and exposed to sunlight. Organic matter like dirt, algae, and sunscreen residue can also contribute to their growth by providing them with a food source.

The porous nature of many pool float materials, such as foam and vinyl, allows mold and mildew spores to penetrate the surface and establish themselves. Over time, these colonies expand and become visible as unsightly black spots. Ignoring these spots can lead to more severe staining and potential damage to the float’s material.

How can I prevent black spots from forming on my pool floats?

Preventing black spots starts with consistently cleaning and drying your pool floats after each use. Rinse them thoroughly with fresh water to remove any dirt, sunscreen, or pool chemicals.
