1kg wiil treat 15,000 gallons pool water.

NOTE :-

• Avoid applying Multi-Stain Remover directly to a vinyl liner or painted surface, as damage may result to the pool surface.
• For vinyl liner spot treatment, place Multi-Stain Remover in a sock or tights, attach to telescopic pole and suspend over stained area.
• For stains throughout a vinyl liner pool, dissolve Multi-Stain Remover in a bucket of water and pour around the perimeter of the pool.
• After treatment a reduction in pH and/or total alkalinity may occur. If adding a pH adjuster (sodium bicarbonate) then do so very, very slowly. Raising the pH and/or total alkalinity too quickly can cause a cloudy pool as well as re-depositing the stain back on the pool surface.
• Be aware that high levels of chlorine will reduce the effectiveness of Multi-Stain Remover. Ideally, reduce the chlorine level to zero before using this product.

What happens when a pool interior stains?

All swimming pools interiors are made from chemical compounds of one type or another. Staining problems can start even before we commence filling the pool with water. Water is corrosive so it must be balanced by careful addition of certain chemicals. Added to this we must sanitise the water continually and re-check the balance to ensure the pool interior is not being attacked by the water itself and also to ensure that bathers are swimming in correctly treated water. 

Staining occurs when insoluble chemical precipitates form in the pool. These may deposit on the pool interior and often they are hard to remove. Stains fall into two categories: Vegetable stains caused by falling leaves and other plant matter; and metal stains caused by dissolved metals in the pool water.

What colour are metal stains?

Iron stains appear as a brown or rust coloured discolouration. Copper stains appear as blue, grey or black discolouration. Manganese stains appear black.

How long after treatment should you wait before swimming?

We recommend you wait 24 hours after treatment.
