Lo-Chlor Salt Stain Remover 1kg – Pool Chemical

Stains can look similar, so a small spot test can help point you in the right direction. Always test a small, inconspicuous area first:

• Vitamin C test: Place a vitamin C tablet (ascorbic acid) in a thin sock and hold it on the stain for 1–2 minutes. If it lightens, the stain may be metal-related (often iron).
• Chlorine test: Place a small amount of granular chlorine (or a tablet) in a sock and briefly hold it on the stain. If it lightens, the stain may be organic (such as algae or leaf staining). Do not leave in contact for long, especially on vinyl.

If neither test changes the stain, it may be scale, oxidation, or a surface-specific issue that needs a different approach.

• Scale is a mineral deposit (often calcium) that usually looks chalky or milky and can feel rough, like sandpaper.
• Oxidation can give fibreglass or painted surfaces a dull, milky, or chalky look (often linked to water balance and sanitiser management over time).
• Stains are colour changes on the surface and can be small patches or cover large areas.

Correct identification matters because different causes respond to different treatments.

Metals can enter pool water in several common ways, including:

• Salt additions (salt can contain trace metals such as iron).
• Top-up water, especially bore or mineral-rich water (iron, manganese, copper).
• Long-term use of some liquid chlorines (trace metals can build up over time).
• Metal-based algaecides (often copper-based).
• Metal fixtures (more common in some above-ground pools).
• Runoff and garden dirt after heavy rain or hosing near the pool.

With metal staining, lifting the mark from the surface is only part of the process. The metal can still be present in the water and may re-oxidise and re-deposit later if the source isn’t addressed.

For longer-term results, focus on both:

• Managing the cause (top-up water, salt additions, runoff, metal-based products), and
• Ongoing prevention with the appropriate Stain Busters product for your stain type.

Some stain treatments work best when chlorine is kept at normal maintenance levels (not elevated). High chlorine can reduce the effectiveness of certain stain removal processes.

Follow the directions on the specific Stain Busters product you’re using, and avoid shock dosing immediately before stain treatment unless the label instructs otherwise.

• Test first: Identify the stain type with a small spot test and treat a small area before committing to a full treatment.
• Circulation matters: Run the pump to help distribute treatment evenly and support filtration.
• Keep water balanced: Stable pH and alkalinity help reduce re-deposit risk and support consistent results.
• Clean filtration: Ensure the filter is operating efficiently (backwash/clean if needed) so the system can capture and remove what it can.

Stain behaviour can vary by surface type (fibreglass, plaster, tiled, vinyl, painted). Always treat a small area first and follow product directions.

For vinyl (especially patterned liners), take extra care with spot treatments using chlorine, as prolonged contact may bleach the surface.

Avoid adding multiple chemicals at the same time. Do not pre-mix products in a bucket.

Add one product, allow it to circulate, then retest and follow the label before adding anything else. This helps prevent unwanted interactions and keeps treatments more predictable.
