Stinky Pinky is a professional-grade rust remover that works where most products can't. Its non-acid formula converts rust compounds into a water-soluble solution, dissolving the stain completely without etching, bleaching, or damaging the surface underneath. No mixing, no diluting, no specialist equipment. Just apply, watch it turn pink, and rinse clean. Stinky Pinky is safe to use on most hard surfaces – please avoid using on leadwork.

The Rust Removal Problem Most Products Make Worse

Rust stains are deceptive. They look like a surface problem but they're a chemical one where iron compounds have bonded to the pores of the material and discoloured it from within.

The instinct is to reach for something strong: bleach, acid, a caustic cleaner. The problem is that these approaches either don't work on rust chemistry at all, as bleach actively worsens rust discolouration, or they remove the stain by damaging the surface along with it.

Hydrochloric acid (also sold as muriatic acid) is the most common active ingredient in conventional rust removers, and while it's effective at dissolving iron compounds, it's also corrosive enough to etch natural stone, strip the finish from terracotta, attack the surface of polished granite, and create secondary damage that's harder to fix than the original stain.

Stinky Pinky takes a fundamentally different approach to rust removal. It contains no caustic acid of any kind. Instead, it uses a targeted chemical reaction to convert iron-based rust compounds into a water-soluble solution that simply rinses away, leaving the surface beneath completely unaffected.

What Causes Rust Staining on Outdoor and Indoor Surfaces?

Rust staining on paving, stone, concrete, and render is more common than most people expect, and it has several distinct causes. Understanding the source helps confirm rust is what you're dealing with, and informs whether future prevention is possible:

Metal garden furniture: chair and table legs left on sandstone, limestone, or concrete paving over time, particularly after rain
Iron-based fertilisers: granules left to dissolve on driveway or patio surfaces leave orange run-off staining
Corroded fixings and wall ties: iron content in mortar or corroding metal fixings behind render leach to the surface as rust streaks
Leaking pipes and tap fittings: water with high iron content dripping from an outdoor tap or pipe fitting onto stone or concrete
Natural mineral content in granite: granite forms with iron-bearing minerals that can oxidise over time, producing rust spotting that emerges from within the stone itself
Tools and equipment: metal tools, watering can components, and plant pots with rusted drainage holes all leave staining on the surfaces beneath them

Non-Acid Rust Remover: Safe on Surfaces Where Others Can't Be Used

The absence of caustic acid in Stinky Pinky's formula is not just a safety consideration, it's what makes rust removal possible on surfaces where conventional rust removers simply cannot be applied. The 1-litre format is confirmed safe for use on all of the following:

Natural stone paving: Indian sandstone, limestone, slate, and flagstone, including surfaces where acid would permanently etch the finish
Granite: including honed and polished finishes where acid exposure causes irreversible surface damage. Stinky Pinky is specifically formulated to be safe on granite, which can develop internal rust spotting from its natural mineral composition
Marble: both indoor and outdoor marble surfaces
Terracotta: garden pots, tiles, and architectural terracotta that are highly sensitive to acid-based products
Porcelain paving and tiles: indoor and outdoor porcelain where acid would attack the glaze
Concrete and block paving: driveways, paths, and patio areas
Brick and masonry: removing rust run-off from external walls, window sills, and building faces
Render: rust streaks from corroding wall ties or fixings behind the render surface
Indoor surfaces: bathroom tiles, kitchen stone, marble worktops, and stone flooring
Wood, paint, fibreglass: Stinky Pinky is safe on painted, fibreglass, and sealed timber surfaces, making it usable on boats, garden buildings, and outdoor furniture frames

The 1-litre bottle covers up to 8 square metres per litre, making it well suited to larger patio areas, extended driveway staining, or multiple surfaces treated in a single session. Stinky Pinky is safe to use on most hard surfaces – please avoid using on leadwork.

The Colour Change That Confirms It's Working

One of the most distinctive characteristics of Stinky Pinky is the visible colour change that occurs during the rust removal reaction. When the product contacts iron compounds in a rust stain, it turns visibly pink. This is a direct, real-time indicator that the chemistry is engaging with the rust and the removal process is underway.

As the reaction progresses, the iron compounds are converted and the colour deepens across the affected area. When the treated area is thoroughly rinsed with clean water, the rust stain goes with it. If Stinky Pinky is applied and no colour change occurs, the staining is not rust, so a different treatment will be required. This reaction confirmation makes the product significantly more diagnostic than conventional rust removers, which offer no visual feedback during the process.

Note: on some surfaces, minor temporary discolouration may be visible immediately after rinsing. This fades within 48 hours and is not indicative of surface damage. Stinky Pinky is safe to use on most hard surfaces – please avoid using on leadwork.

Key Features

Non-acid rust remover: no hydrochloric acid, muriatic acid, or caustic chemistry. Safe on all surfaces where acid-based rust removers would cause damage
Visible colour change reaction: turns pink on contact with rust compounds, confirming the removal process is active and providing clear coverage indication
Converts rust to water-soluble solution: rust compounds are chemically transformed, not bleached or masked, then rinsed away completely
Exceptional surface compatibility: safe on granite, marble, natural stone, terracotta, porcelain, brick, concrete, render, painted surfaces, fibreglass, and wood. Please avoid using on leadwork
Indoor and outdoor use: suitable for exterior paving, render, and masonry as well as interior stone, tile, and bathroom surfaces
Ready to use: no dilution, no mixing, no specialist equipment. Apply by brush or standard garden sprayer
Up to 8m² coverage per litre: suitable for patios, driveways, wall surfaces, and large indoor areas
Diagnostic as well as curative: if no colour change occurs, the staining is not rust. Stinky Pinky confirms what you're dealing with as well as resolving it

Ready to Use: No Mixing, No Measuring, No Specialist Equipment

Stinky Pinky requires no dilution and no preparation. Remove any loose dirt, grease, or debris from the surface before application, then apply directly from the bottle using a brush or standard garden sprayer. Apply a saturated coat across the stained area.

For light rust staining, the reaction and colour change will typically occur within 10 minutes. For heavier or long-established rust staining, allow up to 2 hours' dwell time, reapplying if the surface begins to dry out before the reaction is complete.

Rinse thoroughly with clean water when the reaction has progressed fully across the treated area. For best results on porous surfaces, a second application can be made once the first rinse has dried.

Application Guidelines

Preparation: Remove grease, dirt, and loose materials before application.
Coating: Apply a saturated coat by brush or spray. Rates vary based on surface absorbency.
Reaction Time: Light staining – 10 minutes; heavy staining – up to 2 hours. Reapply if the surface dries out.
Rinsing: Thoroughly rinse with clean water and allow it to dry. Some immediate discolouration may occur on certain surfaces, but it will fade within 48 hours.

Frequently Asked Questions

Stinky Pinky is a professional-grade, non-acid rust remover that uses a targeted chemical reaction to convert iron-based rust compounds into a water-soluble solution. Rather than using caustic acid to dissolve rust which risks damaging the surface along with the stain, Stinky Pinky transforms the rust chemistry so it can simply be rinsed away. The reaction is confirmed by a visible colour change to pink during treatment.

Bleach does not remove rust and should never be applied to rust staining as it can react with iron compounds and actually worsen the discolouration. Acid-based rust removers (those containing hydrochloric or muriatic acid) are effective at dissolving rust but are corrosive to many surfaces, including natural stone, granite, marble, and terracotta. On these materials, acid-based rust removal can cause permanent etching or surface damage. Stinky Pinky's non-acid formula avoids all of these risks.

Yes. This is one of the primary applications. Stinky Pinky is safe on all natural stone surfaces including Indian sandstone, limestone, slate, granite, and marble. These are precisely the surfaces that cannot safely be treated with acid-based rust removers, making Stinky Pinky the correct choice for rust stain removal on natural stone paving and garden surfaces.

Yes. Granite is a mineral-bearing stone that can develop rust spotting from within as its natural iron content oxidises over time, as well as from external sources such as metal furniture or fittings. Stinky Pinky is specifically formulated to be safe on granite, including honed and polished finishes that are sensitive to acid exposure.

Light or recently formed rust staining typically responds within 10 minutes of application. Heavy, long-established rust staining may require up to 2 hours of dwell time, with reapplication if the surface dries out before the reaction is complete. The visible pink colour change is the best indicator of progress. When the reaction has occurred across the full stained area, rinse with clean water.

If no colour change occurs after application, the staining is unlikely to be rust. Stinky Pinky reacts specifically to iron compounds, so if the reaction doesn't occur, a different type of staining is present and a different treatment will be required. This diagnostic property is one of the reasons Stinky Pinky is trusted by professional cleaning contractors.

No. Stinky Pinky is formulated to remove rust staining from finished and porous surfaces, not as a metal primer or rust converter for use before painting bare metal. For metal preparation and rust conversion, a dedicated rust converter primer product is required.

Yes. Stinky Pinky is suitable for use on indoor surfaces including bathroom tiles, stone kitchen floors, marble worktops, and other interior mineral substrates. Its non-acid, ready-to-use formula makes it significantly safer for indoor use than conventional rust removers.

No. Stinky Pinky is safe to use on most hard surfaces – please avoid using on leadwork.
