How to Clean Engine Plastics & Rubber

Why Engine Bay Detailing Matters

Even if you rarely pop the hood, a clean engine bay makes maintenance easier and extends the life of rubber hoses, seals, and plastics. Over time, heat and grime break down these materials, leading to fading, cracking, or even failure. Regular detailing helps:

  • → Prevent rubber from drying out
  • → Keep plastics flexible and dark
  • → Make leaks and problems easier to spot
  • → Improve overall appearance and resale value

Modern engine bays are well-sealed, meaning you can safely clean them with the right products and precautions — no need for harsh degreasers or excessive water.

Tools & Products You’ll Need

  • All Dressed Up – Water-based, streak-free dressing
  • The Super Soaper – Safe pre-cleaner for plastics and hoses
  • Microfiber towels
  • Assorted soft brushes
  • Detailing sprayer or pump foamer
  • Blower or air dryer (optional)

Step-by-Step: How to Clean Engine Plastics & Rubber

Step 1: Cool the Engine

Never clean a hot engine. Wait until it’s cool to the touch to prevent damage to sensors, plastics, or yourself.

Step 2: Pre-Treat with The Super Soaper

Mix 2–4 ounces of The Super Soaper in a pump sprayer and mist over the entire engine bay. Let it dwell for a few minutes to loosen grime, then agitate gently with a soft brush or microfiber towel.

Step 3: Rinse or Wipe Clean

Wipe with a damp microfiber towel to remove dirt and residue. If you prefer, lightly rinse with low-pressure water, avoiding direct spray on electronics. Use a blower or towel to dry thoroughly.

Step 4: Apply All Dressed Up

Once the area is clean and dry, mist All Dressed Up directly onto the plastics, rubber hoses, and trim. Spread evenly with a microfiber applicator or towel for a uniform matte finish. The formula restores deep color without the greasy feel of traditional dressings.

Step 5: Optional – Layer for Shine

If you prefer a slightly darker appearance, apply a second light coat after 10 minutes. For show car looks, buff with a clean microfiber for a smooth satin finish.

Protect Your Engine Plastics & Rubber

All Dressed Up restores faded plastic and rubber while leaving a dry-to-the-touch OEM finish — perfect for engine bays, tires, and trim.
