Disclaimer and Application Tips
Testing Phase Disclaimer: This product is within an ongoing testing phase for outdoor household surfaces. Until we test on all surface types, we cannot accept responsibility for unintended effects. Use sparingly and cease immediately if damage occurs.
Spot testing is mandatory. Always test a small, hidden area before broad application, especially on painted surfaces or natural stone. Not recommended for use on porous stones.
Protect your garden: Be careful around lawns, plants and prized garden displays. Highly acidic runoff can cause yellowing. Direct runoff away from plants and rinse thoroughly. Handle all runoff responsibly to prevent it entering storm drains or waterways.
Get the Best Results Every Time
Keep the Surface Wet
If the paste starts to dry out during dwell time, mist with a spray bottle. A dry crust reduces chemical contact and slows the reaction down.
Work in the Shade
Avoid applying in direct midday sun on hot days. The mixture evaporates too quickly on hot concrete before it has time to react.
Use a Stiff Brush
A deck scrubbing brush or stiff-bristle broom makes light work of stubborn stains after the dwell time. No heavy elbow grease required.
Protect Your Plants First
Wet down nearby plants and lawn edges before you start, then rinse the whole area thoroughly afterward to dilute any acidic runoff away from roots.
One jar. Six different surfaces.
4.9 stars across 2,000+ reviews. Here's one from each surface type.
"I had a metal firepit leak rusty water all over my concrete patio. Made a paste, let it sit for 10 minutes, and the rust completely vanished with a light scrub."
"We use bore water for the sprinklers and it left orange stains all over our front fence. Mixed this in a bucket, brushed it on, hosed it off. The fence looks brand new."
"Bought this originally for the pool, but noticed it said outdoor use too. Tried it on dark leaf stains on my light-coloured driveway pavers. Saved me renting a pressure washer."
"The waterline on my pool looked like it hadn't been cleaned in years. Applied this with a brush while the pool was still full. Absolutely incredible result in under 20 minutes."
"Used it on the concrete slab under my BBQ where grease had been dripping for two summers. It lifted stains that a pressure washer had barely touched. Will not be without a jar again."
"My outdoor table legs had been leaving rusty rings on the tiles for years. Two minutes of paste, one rinse. Gone. Honestly thought I'd have to replace the tiles."
Frequently Asked Questions
The active ingredients are organic and biodegradable. However, it is a highly acidic compound β similar to concentrated vinegar. If heavy, concentrated runoff hits your lawn or prized garden displays, it can cause yellowing and damage. Wet down nearby plants before use and rinse the area thoroughly afterward to dilute any runoff well below harmful concentrations.
Acids can etch or lighten certain natural stones, particularly porous calcite-based ones like limestone, marble, and travertine. This product is not recommended on porous stones. Always perform a spot test in an inconspicuous area first before applying to the full surface, and ensure there is no alteration to the finish before proceeding.
Coverage depends on how heavily stained the surface is. For outdoor pathways and driveways used as a slurry, 1kg generally covers several square metres of heavily stained concrete. For spot-treatments like rust marks from furniture legs, a single jar can last for dozens of individual treatments.
Yes. Apply the formula directly to the oil or grease spot, allow it to dwell for 5 to 15 minutes, then follow up with a stiff scrub and rinse. This lifts stubborn vehicle oil and BBQ grease right out of porous concrete without a pressure washer.
Absolutely β this is the same product originally formulated for use inside swimming pools. It is perfectly safe around pool coping, surrounds, and pebblecrete. Many customers buy one jar to treat both their patio stains and their pool stains on the same weekend. Just rinse runoff away from the pool water.
The multi-jar options add the selected quantity straight to your cart in one click. The savings are reflected in the total at checkout. You get one jar per surface or extra jars to keep on hand for the next clean-up season.
