Copper Stains Removed — Before, During & After
This Miami pool had severe copper staining from corroding equipment — the water had a distinct blue-green tint and the plaster walls were heavily discolored. Our team drained, acid washed, and restored it to crystal-clear condition.

Why Miami Pools Develop Stains & Deposits
Miami-Dade's water supply draws from the Biscayne Aquifer — one of the most productive aquifers in the United States, but also one with naturally high calcium and mineral content. This hard water creates calcium carbonate scaling on pool surfaces, waterline tile, and equipment at a rate significantly higher than most other parts of the country.
Copper staining — one of the most common issues we see — comes from corroding copper equipment (heaters, heat exchangers, older plumbing) or copper-based algaecides. The copper dissolves into the water and deposits onto the plaster surface, creating the distinctive blue-green discoloration visible in our before photos. Salt pools face an additional challenge: the salt cell's pH-raising effect accelerates calcium precipitation onto surfaces.
Types of Pool Stains We Treat
Calcium Scaling
White or grey crusty deposits on pool walls, waterline tile, and equipment. Extremely common in South Florida due to the high calcium content of Biscayne Aquifer water. Acid wash dissolves calcium carbonate buildup that brushing and chemicals cannot remove.
Organic Staining
Brown, green, or black stains from leaves, algae, tannins, and organic matter embedded in the plaster surface. Common in pools near trees or natural areas throughout Cutler Bay, Homestead, and Palmetto Bay.
Copper & Mineral Staining
Blue-green copper stains (from corroding equipment or copper-based algaecides), rust-colored iron stains, or dark manganese deposits. South Florida's well water and older copper plumbing are frequent sources — as seen in our real before/after photos above.
How Our Acid Wash Service Works
Pool Drain
The pool is fully drained. We verify the hydrostatic relief valve is open to prevent the shell from floating due to groundwater pressure — critical in South Florida's high water table.
Surface Inspection
With the pool empty, we inspect the plaster, gunite, or pebble surface for cracks, delamination, or areas requiring repair before the acid wash begins.
Acid Application
A diluted muriatic acid solution is applied to the pool surface in sections. The acid reacts with calcium deposits and stains, dissolving them from the surface layer.
Scrubbing & Neutralization
Each section is scrubbed, then neutralized with a soda ash solution to stop the acid reaction. The neutralized acid and dissolved material is pumped out.
Rinse & Refill
The pool is thoroughly rinsed and refilled with fresh water. We begin chemistry balancing immediately to protect the freshly exposed plaster surface.
Chemistry Startup
Full water chemistry startup: pH, alkalinity, calcium hardness, and sanitizer are all balanced to ideal ranges for a fresh plaster surface to prevent early staining or scaling.
