Required Professional Grill Cleaning Tools and Safety Equipment


Before diving into the cleaning process, you'll need:

  • Angle grinder with knotted cupped wire wheel attachment

  • Drill with flat wire wheel attachment

  • Heavy-duty wire brush

  • Paint scraper

  • Razor blades

  • Degreaser (like Zep Purple or Safecid)

  • Easy-Off Commercial cleaner

  • Microfiber rags

  • Drop cloth

  • Shop vac

  • Stainless steel polish

  • Detailing towels for polish application

  • Protective equipment (gloves, eye protection)


Step-by-Step Professional Grill Cleaning Process


Phase 1: Initial Heat Treatment and Dry Scrape Process


The cleaning process begins with a crucial heat-up phase. Start by warming the grill to 400°F, which helps loosen stubborn grease and debris. While the grill heats, protect your work area by laying down a drop cloth.


  1. Once heated, turn off the grill and begin the dry scrape process.

  2. Use a wire brush to remove loose debris from the grates and bun rack

  3. Apply the angle grinder with wire wheel attachment systematically:

    • Clean the top side of grates

    • Rotate grates 180 degrees and repeat

    • Clean the bottom side

    • Make a final pass after another 180-degree rotation


For thorough cleaning, use a drill with a flat wire wheel attachment to reach tight spaces and intersections in the grates. Remove the grates and place them aside on towels. Use your paint scraper to remove loose debris from flavor bars and heat plates, then place these on the towels as well. Remove the burners and use your shop vac to clean out all loose debris.


Phase 2: Deep Cleaning Grill Interior Components


After the initial scrape, it's time for deep cleaning:

  1. Heat the grill to 250°F

  2. Apply professional-grade degreaser thoroughly

  3. Wipe with microfiber rags

  4. Repeat steps 2 and 3 until satisfied with results.

  5. Use razor blades to carefully remove small grease particles and residue from surfaces

  6. Apply distilled water on all surfaces to remove cleaning product residue


For stubborn spots, use a stainless steel ball on tough areas. Pay special attention to flavor bars and heat plates – these crucial components need thorough cleaning with degreaser, oven cleaner, and an SOS pad.


Once clean, reassemble the interior components and give the grates a final degreaser treatment with an SOS pad scrub. Finish with a water spray to ensure no degreaser residue remains.


Phase 3: Professional Exterior Detailing Process


The exterior deserves just as much attention as the interior:

  1. Clean the drip tray thoroughly

  2. Apply degreaser to the entire exterior surface

  3. Use oven cleaner on stubborn areas

  4. For any discoloration on interior or exterior stainless steel surfaces, apply Bar Keepers Friend using a microfiber cloth and gentle circular motions

  5. Apply stainless steel polish to:

    • Protect against rust

    • Prevent fingerprints

    • Create a professional shine

    • Guard against future spills


Don't forget to polish the interior of the cabinet for a complete professional finish. For cabinet interiors that show discoloration, a gentle application of Bar Keepers Friend can help restore the original finish before applying polish.
