1 part cleaner to 4 parts fresh water in a spray bottle.

How often should I clean tiles?

Monthly during heavy use; quarterly otherwise; annually as a full perimeter deep clean.

Will it damage my grout?

Not at correct dilution. Always test on a hidden patch first.

1 L spray and 5 L refill drums.

Will it harm my liner?

Safe on PVC vinyl liners at correct dilution; rinse promptly. Avoid prolonged contact.

Is it the same as bathroom limescale remover?

Same family but pool-grade is balanced for waterline use; bathroom acids may be too aggressive on grout.

What is the active ingredient?

Phosphoric acid 5-10% w/w with non-ionic surfactant blend.

Phosphoric is gentler on grout than hydrochloric or sulphamic; targets calcium without etching cement.

Will phosphate feed algae?

At rinse-back ppm levels yes, marginally; never let cleaner enter pool unrinsed. Top up phosphate remover at next routine if needed.

Repeat dwell at 10 minutes; switch to undiluted spot application for hardest scale.

Rinse immediately; reduce dilution next time; switch to milder cleaner if persistent.

Tile cleaner vs bathroom limescale?

Pool-grade is gentler on cement grout; bathroom products often etch grout in pool environments.

Tile cleaner vs vinyl cleaner?

Tile cleaner is acidic for scale; vinyl cleaner is detergent-only for plastic surfaces. Different jobs, different chemistry.
