What You’ll Need
Having the right tools on hand makes mold cleanup faster and safer. Assemble these items before you start.
- Blackstone griddle cleaner spray 32 oz mold remover
- Stainless steel grill brush for Blackstone griddle cleaning
- Non-scratch scrubbing pad set for Blackstone griddle cleaning kit
- Outdoor grill mildew remover spray 24 oz for Blackstone

Before You Start
Prepare the work area by removing seasoning and any loose debris. Protect nearby surfaces and wear gloves to minimize skin exposure to cleaning agents. Allow the griddle to cool completely before handling. Time estimate: about 30–60 minutes for a typical mold spot cleanup; up to 90 minutes for a heavily moldy surface. Critical cautions: avoid mixing cleaning chemicals, never steam-clean a hot surface, and never use abrasive pads that could gouge the metal.
Step-By-Step: How To Clean Mold Off Blackstone
- Put on gloves and safety glasses, then scrape off loose debris with the scraper from the griddle cleaning kit.
- Wipe the surface with the outdoor grill mildew remover spray to target mold spots and loosen residues.
- Apply the Blackstone griddle cleaner spray evenly across the surface and let it sit for 3–5 minutes to penetrate mold and grease.
- Scrub using the stainless steel grill brush for Blackstone griddle cleaning to break up mold colonies without scratching the metal.
- For stubborn mold, use the non-scratch scrubbing pad set for Blackstone cleaning to lift embedded spots without damaging the finish.
- Rinse the surface with water or wipe with a damp cloth to remove cleaner and loosened mold residue.
- Dry thoroughly with a clean cloth or allow it to air dry; moisture is a key driver of mold recurrence.
- Reapply a light layer of oil and heat the griddle to bake in a fresh seasoning, then wipe off any excess oil.
- Inspect for any remaining mold; repeat steps 2–7 on persistent areas if needed.
- Schedule regular maintenance: clean after heavy use and store the griddle in a dry, ventilated area to reduce moisture buildup.
Troubleshooting
| Symptom | Likely Cause | Fix | Prevention |
|---|---|---|---|
| Visible mold returns after cleaning | Moisture retention or incomplete removal | Re-clean with mildew remover spray and ensure full drying | Store in a dry area; maintain seasoning to create a protective barrier |
| Streaks or discoloration | Residual cleaner or dried grime | Rinse thoroughly and scrub with non-scratch pad | Rinse and dry promptly after each use |
| Scratches appearing on surface | Overly aggressive brushing | Switch to non-scratch pad and gentler brushing | Use proper cleaning pad for the surface |
| Uneven seasoning after cleanup | Excess oil and heat exposure | Re-season the surface evenly | Follow standard seasoning routine |
Common Mistakes
- Using harsh bleach or ammonia-based cleaners on a hot surface
- Over-wetting the griddle, which promotes mold spread into crevices
- Failing to dry completely before reseasoning, enabling mold return
- Scrubbing too aggressively with metal brushes that gouge the surface
Tips For Best Results
- Clean promptly after cooking in humid conditions to reduce mold growth opportunities.
- Always dry thoroughly and re-season to maintain a protective polymer layer on the steel.
- Use a dedicated mildew remover spray suited for exterior grills to avoid dulling finishes.
- Store the griddle under a cover in a dry space to minimize moisture exposure.
Call A Professional
If mold covers large areas, penetrates the seasoning deeply, or you notice persistent odors even after cleaning, consider consulting a professional. Signs that warrant professional help include extensive rust, structural damage to the cooking plate, or mold spreading under protective coatings. Complex stains that don’t respond to standard cleaners may require specialized treatment beyond consumer products.
