Quick Answer
Work outside in and clean before you dress. Strip the wheel first with a non-acid cleaner, add an iron remover if brake dust is embedded rather than sitting on the surface, then dress the tire and treat the trim last so nothing you spray lands on a surface you still have to clean. Symplex covers each step: Ultimate Wheel & Tire Cleaner for the strip, Iron Wheel Remover for embedded fallout, Glossier or Extreme APD on the tire, and Plasti-K Xtreme or Ceramic Trim SiO2 on the plastic.
Clean before you dress, and work outside in
The corners of a car are the first thing anyone looks at and the last thing most details get to. That's backwards, and it's also why so many jobs end with overspray on a clean panel.
Wheels and tires come first. They're the dirtiest part of the car and everything you do to them throws product around. Trim goes last, after the paint is finished, because trim dressing on paint is a nuisance and trim dressing under a sealant is a failure.
Step one: strip the wheel
Most shops reach for an acid wheel cleaner because nothing else shifts baked-on brake dust fast enough. Then they live with the consequences — etched finishes, damaged trim, and hydrofluoric acid sitting in a spray bottle on the shelf.
Symplex Ultimate Wheel & Tire Cleaner is built on non-acid alkaline technology to close that gap. It contains no hydrofluoric acid, cuts heavy brake dust and road film at production speed, and Symplex lists it safe on painted, clear-coated and polished wheels as well as tire sidewalls. It's a concentrate that dilutes 1:1, so the per-wheel cost stays sensible even in a busy bay.
Non-acid · Dilutes 1:1
Symplex Ultimate Wheel & Tire Cleaner — $14.95
Alkaline wheel and tire cleaner with no hydrofluoric acid. Cuts baked-on brake dust at production speed and cleans sidewalls in the same step. Pint through 5 gallon pail.
Shop NowPro Tip
Spray, agitate, rinse thoroughly — and don't let it dry on the wheel. Every wheel cleaner behaves worse in direct sun on a hot rim, non-acid ones included.
When the brake dust is in the finish, not on it
There's a point where washing stops working. Iron particles from the pads embed themselves in the finish, and no amount of soap and agitation lifts them out because they aren't sitting on top any more.
That's what Iron Wheel Remover is for. It dissolves embedded iron and metallic brake dust chemically, activating fast on contact, and it colour-changes as it reacts — so you can see the decontamination happening instead of guessing at dwell time. It's pH-neutral and ready to use, and Symplex lists it safe on wheels, painted surfaces and glass, which means it doubles as a paint decontamination step before polishing or coating.
Colour-change decon
Symplex Iron Wheel Remover — $23.90
Dissolves embedded iron and brake dust with fast contact activation and a visible colour change. Works on wheels and as a paint decon step. Quart, gallon, 5 gallon pail.
Shop NowYou don't need it every wash. Use it when the wheels still feel gritty after cleaning, or as a decontamination step before you correct or coat paint.
Step two: dress the tire
Solvent tire shines look spectacular in the bay and then throw a stripe of product down the side of the car on the first drive. Both Symplex tire dressings we carry are water-based, which is the fix for that — but they solve different problems.
| Product | Covers | Dilution | Finish control | Starting price |
|---|---|---|---|---|
| Glossier Tire Shine | Tire sidewalls, rubber | Ready to use | Thin for satin, build for gloss | $14.99 |
| Extreme APD | Tires, trim, rubber, vinyl | Dilutes 1:1 | Neat for gloss, cut for satin | $20.99 |
Glossier is the dedicated tire product. Water-based so it won't sling onto paint after application, no solvent smell in an enclosed bay, and the finish is adjustable — go thin for a satin look, build a second coat for high gloss. It runs from a pint up to a 5 gallon pail.
No sling
Symplex Glossier Tire Shine Water-Based — $14.99
Water-based tire dressing that stays on the tire. Deep even gloss, adjustable from satin to high shine, no solvent smell. Pint through 5 gallon pail.
Shop NowExtreme APD is the one-bottle answer instead. It's an all-purpose water-based dressing for tires, trim, rubber and vinyl, and because it dilutes 1:1 you control the gloss level directly — run it neat for high shine on tires, cut it for a satin finish on trim. If you'd rather carry one bottle than three, this is it.
One bottle, three jobs
Symplex Extreme APD Exterior Dressing — $20.99
All-purpose water-based dressing for tires, trim, rubber and vinyl. Dilutes 1:1 so you set the gloss level. Quart, gallon, 5 gallon pail.
Shop NowPro Tip
Apply tire dressing with a foam applicator, not a trigger spray, if the wheel is already clean. Spraying at the tire is how dressing ends up on the wheel face you just spent five minutes stripping.
Step three: bring the trim back
Faded grey plastic ages a car faster than paint defects do, and it's the repair customers notice most. Symplex has two dedicated answers, and the difference between them is durability versus simplicity.
| Product | Type | What it does | Starting price |
|---|---|---|---|
| Plasti-K Xtreme Exterior | Dressing | Restores colour and depth, holds through repeated washing | $18.74 |
| Ceramic Trim SiO2 | Quartz coating | Bonds a quartz layer to the plastic, survives washing and weather | $21.54 |
Plasti-K Xtreme Exterior was formulated against a specific complaint: trim dressings that look correct for a few days and then grey out. It restores depth and colour to faded plastic and rubber, and it's built to hold that finish through repeated washing rather than rinsing straight off. Even, non-greasy, ready to use.

Symplex Plasti-K Xtreme Exterior Pro Dressing — $18.74
Professional exterior trim dressing that survives the next wash. Restores colour and depth to faded plastic, rubber and vinyl without a greasy finish.
Shop NowCeramic Trim SiO2 goes further. Instead of dressing the plastic it lays a quartz layer onto it, so the restored colour is protected rather than reapplied. It's the answer for the customer who's tired of trim that looks right for a week. More work up front, longer before you touch it again.
Quartz coating
Symplex Silex Ceramic Trim SiO2 Quartz Treatment — $21.54
SiO2 quartz treatment that bonds to exterior plastic. Restores colour to greyed trim and holds it through repeated washing, unlike dressing-based products.
Shop NowDressing or coating: which does your trim need?
Use a dressing when the trim is in reasonable shape and the car gets regular attention. It's faster, cheaper per application, and easy to top up whenever you wash.
Use the quartz treatment when the trim is badly faded, when the customer isn't going to be back for months, or when you're already coating the paint and want the whole car on the same maintenance clock. Prep matters more here — a coating bonds to what's underneath, so the plastic needs to be genuinely clean and dry before it goes on.
The full sequence
The bottom line
If you're buying one product off this page, make it the Ultimate Wheel & Tire Cleaner. Non-acid performance that actually shifts baked-on brake dust is the hardest thing to find in this category, and it's the product that keeps hydrofluoric acid off your shelf.
After that it depends how you work. Running volume through a shop? Extreme APD at 1:1 covers tires and trim from one bottle and keeps the cart simple. Chasing the best finish on each car? Glossier on the tires and Plasti-K Xtreme on the trim, with Ceramic Trim SiO2 on the cars you won't see again for six months.
Frequently Asked Questions
Is a non-acid wheel cleaner strong enough for baked-on brake dust?
That's exactly the gap Symplex built Ultimate Wheel & Tire Cleaner to close. It uses non-acid alkaline chemistry to cut heavy brake dust and road film at production speed, without the hydrofluoric acid that etches finishes and damages trim. For contamination that's embedded in the finish rather than sitting on it, add a dedicated iron remover.
What's the difference between a wheel cleaner and an iron remover?
A wheel cleaner lifts dirt, brake dust and road film off the surface. An iron remover dissolves metallic particles that have embedded themselves in the finish, which is why it colour-changes as it reacts. Clean first, then decontaminate only if the surface still feels gritty afterwards.
Why does water-based matter for tire shine?
Sling. Solvent dressings look impressive in the bay and then throw product down the side of the car on the first drive, which means the finish the customer sees leaving isn't the one they have the next morning. Water-based formulas stay on the tire. They also don't fill an enclosed bay with solvent smell.
Can I use Extreme APD on tires and trim both?
Yes — that's what it's built for. It's listed for tires, exterior trim, rubber and vinyl, and it dilutes 1:1 so you can set the finish. Run it neat for high gloss on a tire, cut it for a satin look on trim.
Should I dress trim or coat it?
Dress it if the trim is in decent shape and the car gets regular attention — it's faster and easy to top up. Coat it with Ceramic Trim SiO2 if the plastic is badly faded or the car won't be back for months, because a bonded quartz layer survives washing in a way a dressing doesn't.
What order should wheels, tires and trim go in?
Wheels and tires first, because they're the dirtiest and everything you do to them sprays around. Then the full paint process. Trim goes last, on clean dry plastic, once nothing else is going to land on it.
