Hypo Staining - UPVC

Removing the pink or orange stains left on UPVC after using sodium hypochlorite requires a careful approach to avoid further discoloration or surface damage. These stains are typically caused by a reaction between the bleach and trace minerals, like iron, on or near the UPVC surface. To safely treat these marks, PureSeal recommends a gentle acidic cleaner specifically designed to target mineral-based discoloration. This approach allows for effective stain removal while protecting the integrity and appearance of the UPVC. For best results, perform a test patch in an inconspicuous area before full application.

Using the recommended PPE for safe handling is essential, especially when working with acidic solutions. Closely follow product instructions and monitor the process to avoid leaving the cleaner on the surface for too long. Controlling runoff is also crucial to prevent unintended staining on surrounding materials or surfaces. With PureSeal’s targeted solutions, professionals can restore UPVC to its clean, original state, effectively lifting unwanted stains without compromising the material’s durability or finish.
