Solution: Pinkish staining is a by-product of a micro-organism called Streptoverticillium Reticulum. The micro-organism is often present in areas of high humidity and is usually deposited by the rain.
Although the vinyl coating on a spa is treated to resist bacteria (meaning it is not a suitable food source), it is still a perfect host site for this particular micro-organism. Other than looking strange, staining should not affect the use of your liner or enjoyment of your spa.
Despite the fact that the pinkish staining is extremely difficult to remove, regularly cleaning your liner should prevent Streptoverticillium Reticulum from ever appearing.
Unfortunately, this is not a manufacturing defect and the Aftersales Team will not be able to replace this under warranty for you. The pinking will not cause any problems with using the spa but unfortunately, will look unsightly. Replacement liners can be purchased from our Lay-Z-Spa Covers & Liners category.
Solution: This is usually caused by the liner being damp when putting your Lay-Z-Spa away for the winter. Mould can be cleaned using diluted washing up liquid or the Clearwater Scale and Stain Remover. This product will not harm the liner in any way.
