How do I use Bathroom & Shower Cleaner in the Foaming Spray Bottle?Updated 6 hours ago

No. Bathroom & Shower Cleaner is a ready-to-use formula. It ships in a 1.8L bag-in-box: a cardboard outer with a flexible bladder inside. Pour directly into Foaming Spray Bottle as it comes. Adding water dilutes the formula and reduces cleaning performance. Don't mix it with other products either, combining cleaners can deactivate ingredients or create unwanted reactions.

⚠ Ready-to-use, do not dilute

Pour straight into Foaming Spray Bottle. No water, no mixing with other products. The formula is designed to work at the concentration in the box.

Open the spout on the bag-in-box and dispense directly into the Foaming Spray Bottle. Fill to just below the shoulder of the bottle, leaving a small air gap so the foamer mechanism can operate properly. Screw the foaming head back on firmly. Ready to spray. The 1.8L refill fills the foaming bottle roughly four times, which works out to around 3 months of weekly bathroom cleaning.

✓ Fill in 3 steps

Two foam lines in a criss-cross pattern (one horizontal, one vertical) across the surface is enough for light to moderate soap scum and bathroom grime. For heavy build-up, add two diagonal lines to create a star pattern. Don't drown the surface, more foam doesn't mean better clean, it just means more rinsing. Let the foam dwell for a few minutes so the formula can break down grime, then wipe with Ultra Pro Bathroom Mitt and rinse.

A few minutes for weekly maintenance (2 to 3 minutes). Up to 5 minutes for moderate soap scum. Up to 10 minutes for heavy build-up or limescale. Longer dwell means the enzymes and surfactants have more time to break down grime, so you scrub less and get better results. Don't let the foam dry out fully, re-spray if needed. Rinse thoroughly with water after wiping.
