Stain Removers
Lo-Chlor chemicals are Australia's only specialty chemical manufacturer. Their unique range of stain removing products can magically remove 95% of unsightly swimming pool surface stains through a simple chemical treatment.
Before considering stain removal, you must be aware of exactly why a pool 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. For our purposes, stains fall into two categories: organic/vegetable stains caused by falling leaves and other plant matter and metal stains caused by dissolved metals in the pool water.
ORGANIC / VEGETABLE STAINS: These are caused by organic material falling into the swimming pool, often leaf stains or leftover marks from algae problems.
Spot dosing with granular chlorine is the easiest way to remove vegetable stains. Care should be taken not to bleach the pool surface, particularly when treating a patterned vinyl liner. It is suggested that the chlorine be suspended near the stain (use a synthetic sock or pantyhose).
METAL STAINS: This is a very complex subject. Metal stains occur when levels of metals or minerals reach saturation point in a pool's water. The metals will go from a suspended state to a solid on the surface of the pool resulting in discolouration of the pool surface. These are almost impossible to remove by scrubbing or any other chemical treatment. Metal stains are normally caused by dissolved iron or copper. Iron stains appear as a brown or rust coloured discolouration. Copper stains appear as blue, grey or black discolouration.
Iron staining occurs quite often in fibreglass pools. Traditional methods of treatment have included addition of various organic acids. These tend to alter the water balance significantly and may affect the chlorine reading on conventional test kits. Lo-Chlor Chemicals have developed a product called CITRA-CLEAN specifically to remove iron stains.
Lo-Chlors unique stain removal treatments are stain specific, so it is important to ensure that your stain is correctly identified so the correct product is used.
