NOT JUST ORDINARY DIRT

Those Orange Rings & Chalky Marks Need More Than Everyday Wiping

Hard water can leave mineral buildup that makes a bathroom look dirty even after routine cleaning.

🟠

Rust-Colored Marks

Orange or brown discoloration around drains, toilet bowls and water-contact areas.

💧

Hard-Water Film

Cloudy mineral residue that can leave compatible surfaces looking dull.

🪨

Limescale Buildup

White, rough or crusty deposits around frequently wet bathroom areas.

💪

Repeated Scrubbing

Going over the same spot without first loosening the mineral deposit.

Don’t just scrub harder. Match the cleaner to the buildup.

Frequently Asked Questions

What type of stains is this cleaner best for?

It is designed for visible mineral-based bathroom stains such as rust discoloration, limescale and hard-water residue.

Can I use it on marble or natural stone?

No. Oxalic-acid cleaners may damage acid-sensitive materials such as marble, limestone, travertine and some natural-stone finishes.

Does it require scrubbing?

It helps loosen buildup before wiping, so less hard scrubbing may be needed. Heavy deposits may require repeat treatment or gentle agitation if the label permits.

Should I rinse the surface afterward?

Yes. Wipe and rinse the treated area thoroughly after the recommended contact time unless the label states otherwise.

Can I mix it with bleach or another cleaner?

No. Never mix it with bleach, ammonia or another household cleaner. Use only as directed and ventilate the area.

Can I use it on toilets, sinks, tubs and tile?

Use only on compatible surfaces. It can be used on toilet bowls, porcelain sinks, bathtubs and compatible tile where mineral buildup is visible. Test a small area first.

What if the buildup is especially heavy?

Follow the label-directed contact time and repeat only if permitted. Do not leave the product on longer than directed.

How much product is in one bottle?

One bottle contains 100 ml (3.38 fl oz).
