Blog Title: “Solving Discoloration on Acrylic Spa Surfaces: Prevention and Repair” In the world of spa maintenance, preserving the pristine condition of acrylic surfaces is paramount for owners. A common yet perplexing issue some may encounter shortly after acquiring a new spa is the appearance of yellow stains or discoloration on its surface. Understanding the cause and identifying effective solutions for this problem are essential for maintaining the aesthetic appeal and integrity of your spa.

The Root Cause of Acrylic Spa Surface Discoloration

The discoloration of acrylic spa surfaces is predominantly attributed to chemical attacks, often resulting from the use of inappropriate water treatment chemicals or fragrances. A notable offender in recent times is “Tri-Chlor” (Trichloroisocyanuric acid), a chemical compound widely used in tablet form for swimming pool water treatment. While highly effective in pools, Tri-Chlor poses a risk to acrylic spas due to its acid content, which can aggressively bleach the pigments in the acrylic material. This issue arises when the dispenser, designed to float and gradually dissolve the tablet, settles along the spa’s edge, exposing the nearby acrylic surface to concentrated acid levels.

Preventive Measures and Manufacturer Insights

Recognizing the prevalence of this issue, one leading acrylic manufacturer undertook laboratory testing to validate the adverse effects of Tri-Chlor on acrylic pigments. Their findings confirmed that Tri-Chlor could indeed bleach the vibrant pigments used in acrylic spas. As a response, they have issued technical bulletins and produced warning labels advising against the use of Tri-Chlor in spas. These labels are now recommended for inclusion on all new spa units by manufacturers and dealers alike.

For spa owners seeking to avoid such chemical damage, it’s crucial to consult the product’s operation manual, seek advice from qualified dealers, or contact the manufacturer directly for recommendations on safe water treatment chemicals. An alternative to Tri-Chlor is “Di-Chlor”(Dichloroisocyanuric acid), available in powder or granular form, which is a less aggressive acidand commonly recommended for hot tubs and spas.
