Brown, grimy tires can spoil the look of an otherwise clean car. In this video, Bradley explains the common causes of tire browning and demonstrates how to clean the sidewalls with Armour Detail Supply Tire Cleaner before finishing with Tire+.

Why tires develop a brown or dirty appearance
Brown sidewalls do not all have the same cause. Road film can collect on the rubber, old dressing can hold onto contamination, and protective additives within the tire can migrate to the surface. That last process is commonly described as tire blooming. Michelin's explanation of sidewall discoloration also describes this as a normal surface occurrence.
Bradley's demonstration separates a heavy cleaning reset from ordinary maintenance. The aim is to remove accumulated film and leave an even surface for dressing. It is not to repeatedly attack a clean tire with the strongest available cleaner or to promise that normal blooming can never return.
Inspect the sidewall before treating appearance issues. Cleaning and dressing improve the finish; they do not repair cuts, cracking, bulges, or other physical tire damage.
Choose your cleaner strength correctly
Tire Cleaner is available in different formats. The current 16 oz bottle is ready to use, already prepared at a 2:1 dilution for deeper cleaning. The gallon contains concentrate, which can be measured into a separate application bottle.
| Job | Current concentrate guidance |
|---|---|
| Heavy tire cleaning | 2 parts water to 1 part product. |
| Maintenance cleaning | 4 parts water to 1 part product. |
Ratios are water to product. For example, a 500 mL batch at 4:1 contains 400 mL water and 100 mL concentrate. Do not confuse a concentrate recipe with instructions to add that amount to the already diluted ready-to-use bottle.
Choose the strength for the actual dirt and follow the current label. The video uses a deep clean to establish a clean starting point, then recommends a milder maintenance routine afterward.
Gather tools that can reach the sidewall texture
A dedicated Detail Factory ProGrip Tire Brush helps clean around raised lettering, patterned rubber, and small recesses. Use tools intended for tire work and keep them separate from the soft media you use on paint.
Have water ready for a thorough rinse, plus a way to dry the tire before dressing. Prepare Tire+ and a Comfort Grip Tire Applicator for the finishing stage so the tire can be dressed after inspection.
Step-by-step deep cleaning process
- Work on a cool tire. Choose an area out of direct sunlight and follow the cleaner's protection and compatibility directions. Keep Tire Cleaner away from raw, uncoated aluminum and other excluded surfaces.
- Pre-rinse the sidewall. Remove loose dirt and wet the working surface.
- Apply the cleaner. Give it a brief dwell of roughly 20–30 seconds as shown in the demonstration. Do not let the product dry.
- Agitate with short, controlled passes. Work around lettering and grooves instead of making a couple of fast swipes across the entire tire.
- Rinse thoroughly. Flush the chemical and loosened dirt from the texture and surrounding wheel area.
- Inspect and repeat only as needed. If visible film remains, another controlled cleaning pass may be appropriate.
Bradley's first pass makes a large visible improvement. The second pass produces much cleaner foam and helps address areas that did not receive enough attention initially. Foam color is useful feedback, but inspect the rubber itself rather than endlessly repeating a strong chemical cycle to chase a particular foam color.
What about sticky old dressing?
The video also discusses tires covered in a thick layer of old dressing. That contamination can interfere with ordinary cleaning. Bradley demonstrates a separate residue-removal step for that situation, while emphasizing that it is not something to do at every wash.
Only use a residue remover specifically compatible with the tire and the surrounding wheel finish. Do not assume that a general solvent is safe because it removes the visible film. Follow the product and tire manufacturer's instructions, then complete the normal tire-cleaning and rinsing steps.
Apply Tire+ to clean, dry sidewalls
- Dry the tire and inspect for remaining cleaner or uneven buildup.
- Apply a small amount of Tire+ to the applicator.
- Spread an even layer across the sidewall, including the narrow area near the wheel lip.
- Keep dressing off the tread and braking surfaces.
- Allow it to dry and remove excess or uneven patches with a suitable dedicated towel.
Bradley's preferred result is a clean satin appearance. More dressing is not automatically better. Starting with an evenly cleaned surface helps the product spread consistently; applying a heavy layer over dirt can leave a patchy finish.
Keep the result with regular maintenance
Inspect the tires during subsequent washes and use the cleaning strength needed for that condition. A tire that has accumulated months of old dressing needs a different approach from a regularly maintained sidewall. Reapply dressing when appropriate after cleaning and drying.
For the rest of the vehicle, see our maintenance wash guide. Dedicated wheel tools, clean tire applicators, and controlled product amounts make this easier to repeat.
Frequently asked questions
Does browning always mean the tire is defective?
No. Surface discoloration has several common causes, including normal blooming. Assess physical tire condition separately from how clean the rubber looks.
Why does the dressing look uneven?
Check for leftover old dressing, dirt, moisture, and excess new product. Correct the preparation rather than immediately layering more dressing over the patch.
Will one deep clean prevent all future browning?
No permanent guarantee is appropriate. Driving conditions, tire composition, contamination, and maintenance all affect the appearance over time.
