This will be a messy job, but cleaning your wheel wells is very doable. Start by getting all the dirt off. Using a pressure washer or hose both work well for this.
Scrubbing the wheel well with soap also works, although you’d have to get much closer to the mess!
With the dirt dealt with, coat your wheel wells with an all-purpose cleaner or degreaser. Then, scrub the wheel wells with a brush. You can buy a special wheel well brush from most auto stores for $10.
With that, your wheel wells should be clean. If you want to protect your wheel wells from a further mess, there are undercarriage sprays you can find at auto retailers that help repel dirt.
