303 Products Heavy Duty Wheel Cleaner — 15.5 fl oz iron-indicating, acid-free rim cleaner safe on aluminum & painted alloys

If your wheels are coated in baked-on brake dust or your paint shows embedded fallout, this wheel cleaner offers a concentrated, iron-indicating formula that loosens contaminants without harsh acids or overpowering fumes. The spray-on solution clings to surfaces, changes color where iron particles are present, and rinses off cleanly—making it useful both for wheel restoration and as a decontaminant step before paint correction.

How quickly does it remove brake dust and iron deposits?

The formula begins working on contact, visually signaling iron contamination with a purple color change while softening grime for easy removal. Typical use requires only a short dwell time and light agitation in stubborn areas.

• Apply liberally to cold wheels and allow 1–5 minutes to work.
• Purple color indicates iron conversion; rinse thoroughly after reaction.
• Minimal brushing needed for heavily soiled lug areas and barrels.
• Safe repeat use—non-corrosive, acid-free chemistry protects finishes.

Will this cleaner damage my wheel finish or tires?

303’s heavy-duty cleaner is formulated without strong acids or corrosive ingredients, so it is appropriate for a wide range of wheel materials when used as directed. Avoid use on hot surfaces and always rinse thoroughly to prevent residue.

• Suitable for aluminum, chrome, steel, and painted alloy wheels.
• Non-corrosive formula reduces risk of etching and discoloration.
• Not intended for rubber trim or unsealed porous surfaces—spot test if unsure.
• Works safely as a decontaminant on painted panels when rinsed promptly.

How do I use it for best results and prep for polishing?

Use this product as part of a two-step cleaning: remove heavy deposits from wheels first, then follow with a dedicated decon or clay step on paint if preparing for polishing. The cleaner’s iron-indicating action makes it simple to verify thorough contaminant removal.

• Rinse loose dirt, spray liberally over cold wheels, wait 1–5 minutes.
• Agitate with a soft wheel brush on stubborn build-up, then rinse clean.
• For paint decontamination, spray, let react, and rinse before claying/polishing.
• Repeat application if heavy iron staining remains after first rinse.
