Purus Rim Cleaner 500ml – Wheel cleaner for all types of rims

Quick summary: Purus Rim Cleaner 500ml is an acid-free, pH-neutral wheel cleaner that dissolves burnt-on brake dust, road grime and grease in 2 to 3 minutes. The formula is safe for alloy, steel, coated, polished, chrome and dip-coated rims. One 500ml bottle is sufficient for an average of 8 to 12 full treatments (4 rims per session), depending on the level of soiling. The product is formulated and manufactured in the Netherlands.

You’ve just driven back from the car wash. The bodywork is spotless. The wheel rims, however, are still dark and encrusted with a layer of burnt-on brake dust that simply won’t come off. This brake dust consists of metal particles from brake discs and pads that burn onto your wheel rims at high temperatures. Ordinary car shampoo won’t sort that out — you’ll need a specific Rim Cleaner 500ml required, with an active iron-dissolving formula.

What exactly does a rim cleaner do, and why does the 500ml size work so well?

A wheel cleaner (also known as a rim cleaner or non-ferrous cleaner) contains active compounds that react specifically with iron-containing metal particles — the main component of brake dust. This chemical reaction is visible when the liquid turns purple: this is not a gimmick, but a reliable indicator that the product is working effectively.

The 500ml bottle is the most practical size for domestic use. With an average usage of 10 to 15 ml per wheel rim for normal soiling, and 20 ml per wheel rim for neglected maintenance, one bottle will last for 8 to 12 or 6 to 8 full washes respectively. This makes the price per treatment considerably lower than that of competitors’ smaller spray bottles.

Purus Rim Cleaner goes one step further by calibrating the formula so that it dissolves dirt without damaging the paintwork or protective coating on the wheel rim. That distinction is crucial — particularly for coated rims or those with a ceramic coating.

Which types of rims are suitable — and what should you look out for?

Not every wheel cleaner is suitable for every type of wheel. That’s the first thing you need to know before you spray anything onto your wheels. Acidic wheel cleaners (based on phosphoric acid or hydrochloric acid) are effective against stubborn dirt but can damage unpainted steel, polished aluminium and ceramic-coated wheels. pH-neutral and acid-free formulas such as Purus Rim Cleaner are safer for a wide range of surfaces.

Purus Rim Cleaner 500ml vs. the competition

There is a wide range of wheel cleaners available on the market. Below is an impartial comparison based on the criteria that really matter in practice.

Step by step: how to use Purus Rim Cleaner correctly

The technique makes all the difference between an average result and an excellent one. This is the method that works.

1. Leave the rims to cool down. Never work on hot wheel rims or brakes. Wait at least 30 minutes after riding before you start.
2. Get out of the sun. Direct sunlight causes the product to dry too quickly, resulting in stains.
3. Spray the rim cleaner evenly onto a dry or slightly damp rim. Use approximately 10–15 ml per wheel rim for normal soiling; for heavy soiling, you may need up to 20 ml.
4. Leave on for 2 to 3 minutes. The liquid turns purple as it reacts with iron particles from brake dust. Once the colour change stops, the product has run out.
5. For stubborn dirt, use a soft wheel brush. Work along the rim spokes and around the rim to mechanically scrub away any caked-on dirt.
6. Rinse thoroughly using a powerful water jet or high-pressure cleaner. Make sure no residue is left behind.
7. Dry with a clean microfibre cloth to prevent water marks, particularly on polished and chrome wheels.

⚠️ Safety warnings: Do not allow to dry on the surface. Do not use on hot wheel rims or brakes, or in direct sunlight. Keep out of reach of children. Avoid contact with the eyes — preferably wear gloves and safety goggles. In case of contact with the eyes, rinse immediately with water. Keep the safety data sheet; the SDS document is available via the product page.

Myth vs. fact: what’s really true about wheel cleaners?

Myth: Wheel cleaners always damage the paintwork on your wheels.
Fact: Acid-free and pH-neutral formulas have been specifically developed to safely dissolve dirt without damaging the wheel paintwork or protective coating. Harsh, acid-based cleaners, on the other hand, do — which is why the type of formula must always be stated on the packaging.

Myth: Ordinary car shampoo cleans wheel rims just as well.
Fact: Car shampoo is not capable of chemically dissolving burnt-on brake dust (metal particles that adhere to the rim surface at high temperatures). A specific non-ferrous cleaner is required for this.

Myth: A larger bottle is always better value.
Fact: The yield depends on the concentration of the formula. The Purus Rim Cleaner 500ml is ready to use undiluted and provides 8–12 washes — which is comparable to, or better than, larger bottles from brands with a thinner formula.

Common application issues — and how to resolve them

Dried-on stains: If you’ve left it for too long or are working in the sun, purple residue stains may remain. Spray the rim again straight away with Rim Cleaner, leave it to work for a very short time, and then rinse thoroughly straight away. Dry with a microfibre cloth afterwards.

Some of the brake dust remains: For wheel rims that have been neglected for years, a single treatment is sometimes insufficient. Repeat the treatment and use a soft wheel brush to scrub the dirt off mechanically. Three consecutive treatments will also remove even stubborn burnt-on deposits.

The product does not turn purple: If there is little or no colour change, this indicates that there is very little iron-containing brake dust present. This means that the rims are relatively clean — the product is simply doing its job; there is little for it to react with.

Bas T. – Utrecht | ★★★★★

Frequently Asked Questions about Purus Rim Cleaner 500ml

Is Purus Rim Cleaner 500ml safe for polished or ceramic-coated wheel rims?
Yes, the acid-free and pH-neutral formula is safe for virtually all types of wheels, including polished aluminium and coated wheels. For ceramic-coated rims, keep the application time short (maximum 2 minutes) and rinse thoroughly afterwards to avoid putting unnecessary strain on the coating.

How much product should I use per wheel, and how long will a 500ml bottle last?
For normal dirt, use approximately 10 to 15 ml per wheel rim. With four wheel rims per wash, a 500 ml bottle will last for 8 to 12 washes. For heavily soiled rims, allow 20 ml per rim, which equates to 6 to 8 washes.

Can I use the product on hot wheel rims or straight after driving?
No. Always wait at least 30 minutes after driving before you start. On hot wheel rims, the formula dries too quickly, which can lead to white residue stains that are difficult to remove.

What is the difference between a pH-neutral wheel cleaner and an acidic wheel cleaner?
Acidic wheel cleaners (based on phosphoric acid or similar acids) are more aggressive and can damage untreated metal and soft coatings. pH-neutral and acid-free formulas such as Purus Rim Cleaner work by reacting chemically with iron particles and are therefore safer for a wide range of wheel types — including polished aluminium and dip-coated wheels.

How often should I clean my wheel rims with Purus Rim Cleaner?
Under normal conditions, one treatment per wash (every 2 to 4 weeks) is sufficient to prevent brake dust build-up. Drivers who do a lot of city driving or drive in a sporty manner (more frequent braking, higher disc temperatures) may wish to consider cleaning their brakes weekly.
