Prepare Your Gear

What You’ll Need to Tackle the Undercarriage Grime Fest:

Ready to wage war on the dark side of grime? Let’s gear up and get to it!

Step 1: Prepare Your Wash Bucket

Preparing Undercarriage Wash Solution
  1. Grab your Heavy Duty Ultra Clear Detailing Bucket, 4.25 Gal, and fill it up with water. Think of it as your cleaning cauldron.
  2. Add a few generous glugs of AllClean+ All Purpose Cleaner, adjusting the ratio depending on how filthy your undercarriage is:

    • Tough Gritty Grime: Go heavy on the cleaner.
    • Light Dust Duty: Dial it back.
  3. Blast the mix with your hose to agitate the suds into action—think bubbly reinforcements ready to knock off dirt and grime.

Congrats, you’ve just created the ultimate foamy solution to make the cleaning process smooth, efficient, and oddly satisfying.

Step 2: Start Cleaning Your Undercarriage

Rinsing the Undercarriage
  1. Rinse It Down: Start by giving your undercarriage a thorough rinse to flush out loose dirt, mud, and mystery road gunk. This prevents accidental scratches when you start scrubbing.
  2. Spray & Soak: Douse your undercarriage with AllClean+ All Purpose Cleaner, making sure to hit every dirt-covered nook and cranny. Pay extra attention to the trouble zones where grime loves to camp out.
  3. Scrub & Rub:

  4. Inspect & Reapply: Did you miss a spot? There's no shame in the re-spray game. Hit it again with cleaner and give it another scrub until everything is sparkling clean.

This step is all about banishing every last trace of dirt—because a half-clean undercarriage is just sad.

Step 3: Rinse and Dry

Rinse and Dry
  1. Rinse it Right: Blast away every trace of AllClean+ All Purpose Cleaner with a thorough rinse. Leftover cleaner? Not on your watch—it could lead to corrosion, and nobody’s got time for that.
  2. Dry Time: Let your undercarriage air-dry naturally, or crank things up a notch with the Metro Sidekick High Speed Professional Blower. It’s like a hair dryer for your car but way cooler (and faster).
  3. Why It Matters: Drying isn’t just for show—it’s the crucial prep step before applying the protective dressing. No one wants water getting in the way of that perfect, lasting finish.

Once it’s bone-dry, you’re ready to move on to the grand finale: protection.

Step 4: Apply BareBones Undercarriage Dressing

Applying Barebones to undercarriage
  1. Spray or Swipe: Hit those tricky spots directly with BareBones Undercarriage Dressing, or for a more controlled approach, apply it using a Premium Grade Microfiber Applicator. Either way, the goal is full, even coverage.
  2. Work It In: Spread the dressing evenly, making sure it gets into every crevice. This step isn’t just for show—proper application means maximum protection for all those hardworking components under your ride.
  3. Pick Your Finish:

    • Glossy Glam: Let BareBones air-dry for that rich, factory-fresh sheen.
    • Muted Matte: Prefer to keep it low-key? Gently buff away any excess with a Workhorse Professional Grade Microfiber Towel, folding it into sections for a clean pass each time.

Your undercarriage is now dressed to impress, ready to face whatever dirt, grime, or salt life throws at it.

Sure, cleaning your undercarriage might feel like tackling the dark abyss of car care, but with the right tools and a little know-how, it’s a total game-changer. Not only will your ride stay in peak performance mode, but it’ll also look ridiculously good doing it.

Follow this guide, and you’ll not only protect your car’s vital parts but also keep it looking showroom-fresh. Because let’s face it—your car deserves better than dirt and grime clinging to its underbelly. Now, go out there and show those roads who’s boss!
