Stains in your Naples pool can appear suddenly and turn a relaxing oasis into a frustrating eyesore. This article explains how to identify pool stains, treat them using proven methods, and prevent future discoloration—focusing on tips from 239-POOL-JOY, Naples’ leader in local pool service and leak detection. Learn how to keep your pool sparkling clean with the most effective stain removal options available in Southwest Florida.
Pool stains are a common problem in Naples, FL due to the local water chemistry and the region’s subtropical climate. Stains often form from metal deposits (copper, iron), calcium buildup, algae, and organic matter. Sunscreen, body oil, and debris from landscaping can also settle on pool surfaces and create unsightly spots.
Without proper pool maintenance and regular pool cleaning services, stains may embed in your pool’s surface or pool walls. Naples pools, especially those with lighter finishes, are more prone to visible stains due to these environmental factors.
There are many kinds of stains found in Naples pools. Metal stains from copper and iron often look blue-green or rusty brown. Organic stains may come from leaves or alga, showing up as dark spots on pool walls or the bottom. Mineral stains, including white or gray calcium deposits, create rough spots along the waterline.
Identifying the stain type is the first step in successful stain treatment. Pool owners should note the stain’s color, texture, and location before choosing a cleaning method or stain remover. Routine inspections help catch stains early, making removal easier.

Alga blooms are common in Naples, FL pools—especially in warm, wet conditions or after heavy rains. Algae stains appear as green, yellow, or even black spots on the pool’s surface or tile. These stains can be stubborn if not treated quickly, leading to deeper discoloration in the layer of plaster or pool finish.
Regular chlorination, balanced water chemistry, and cleaning schedules can help prevent algae stains. Scheduling maintenance with a professional pool service like 239-POOL-JOY ensures your pool clean and healthy year-round.
An acid wash is an effective stain removal method, especially for tough calcium deposits, metal stains, and persistent algae spots. Pool acid wash involves draining the pool and applying an acid mixture (often muriatic acid) to dissolve stains on the pool’s surface.
Professional acid wash services in Naples restore your pool’s finish and remove stains without damaging the layer of plaster. Acid wash should only be used when other cleaning methods have failed, and only with proper safety precautions. 239-POOL-JOY offers acid wash services for the Naples area, ensuring the process is safe and effective.
Our echnicians identify the type of stain—metal, mineral, organic, or algae—and tailor a stain treatment approach based on the specific needs of the pool owner.
Specialty stain removers, targeted brushing, and precision cleaning ensure stains are removed without harming the pool’s finish. For resistant stains, acid wash may be recommended, but only after all alternative solutions are considered.
Routine surface cleaning helps prevent stains from setting, but stubborn stains often require enhanced chemical treatment or professional removal. Scrubbing with a pool brush and using specific products designed for stain removal will lift most minor stains; for severe calcium or metal stains, stronger solutions may be required.
