How do I use Bathroom & Shower Cleaner?Updated 7 hours ago
TL;DR: Spray Bathroom & Shower Cleaner onto the surface, spread the foam with a damp sponge or cloth, let it sit for a few minutes to break down grime, scrub with the Ultra Pro Bathroom Mitt for tough soap scum, then rinse clean with water. More dwell time means better results. For weekly maintenance, skip the scrub and just spray, wait, wipe.

How do I use Bathroom & Shower Cleaner?
Spray Bathroom & Shower Cleaner directly onto the surface and spread the foam evenly with a damp sponge or cloth. Let it sit for a few minutes so the formula can break down dirt, soap scum, and body oils. Scrub any remaining grime with the Ultra Pro Bathroom Mitt. Rinse away with water. That's the complete method for a sparkling, streak-free bathroom.
✓ Five-step method
Spray the foam. Spray Bathroom & Shower Cleaner directly onto the surface. Cover the full area.
Spread with a damp sponge or cloth. Even out the foam so every part of the surface has contact.
Let it sit. A few minutes for light maintenance, up to 10 minutes for heavier soap scum or build-up. More dwell time means better results.
Scrub tough grime. For hardened soap scum, limescale, or textured surfaces, scrub with the Ultra Pro Bathroom Mitt. For weekly maintenance, skip this step.
Rinse clean. Rinse with water. Sparkling, streak-free shower screens, tiles, and surfaces.
How long should I let it sit?
A few minutes for everyday maintenance cleaning. For heavier soap scum, limescale deposits, or bathrooms that haven't been cleaned in a while, leave the foam on for up to 10 minutes. Don't let it dry out fully, re-spray if needed. Longer dwell time gives the enzymes and surfactants more time to break down grime, so you scrub less and get better results.
✓ Dwell time by soiling level
Weekly maintenance: 2 to 3 minutes. Moderate soap scum: 5 minutes. Heavy build-up or limescale: up to 10 minutes. Don't let the foam dry out fully. Re-spray if needed.
What bathroom surfaces can I use it on?
Shower screens, tiles, grout, bathtubs, basins, taps, shower trays, fibreglass, acrylic, stainless steel, chrome, glazed ceramic, and painted surfaces. Bathroom & Shower Cleaner is designed for the full bathroom. Spot test on natural stone (marble, travertine, limestone) and on any surface you're unsure about. Avoid prolonged contact with aftermarket glass coatings or tint films.
✓ Works across the bathroom

How often should I use Bathroom & Shower Cleaner?
Once a week for maintenance cleaning prevents build-up and keeps the bathroom consistently fresh. For shower screens specifically, a quick spray and wipe after use (once or twice a week) prevents soap scum from ever hardening in the first place. The 1.8L refill pack covers roughly 3 months of weekly use. Subscribe & Save every 3 months to keep the routine running.
✓ Weekly for maintenance
Weekly is the sweet spot for keeping a bathroom consistently fresh. For shower screens, a quick spray-and-wipe after use prevents soap scum from ever hardening. One 1.8L refill lasts around 3 months of weekly cleaning.
