Yes. In fact, this is one of the situations where our product really shines.
We specifically tested abandoned grills—one test grill had visible rust, mineral sediment, and decades of dirt dug out (no joke).
Here's what happens: You turn on the brush. The interlocking bristles start breaking down surface rust and stubborn dirt. You pass 3-4 times, focusing on the worst areas.
The first pass: 60% of the dirt gone. The second pass: 85% gone. The third pass: 98% clean.
For real rust (not surface rust): If it's DEEP rust (i.e., holes in the cast iron), not even we can magically fix it. But if it's SURFACE rust (brown-red on the surface), the brush removes it completely.
The real value: It's not just cleaning—it's saving the grill. If that grill was abandoned and unusable, our product brings it back to life. It's worth much more than the price.
Pro tip: If the grill is VERY rusty, do a slow initial pass. This will "break up" the rust. Then do a second, quicker pass. Rinse between passes.
If the rust is DEEP (holes you can fit a finger into), we can't save that grill. Nothing can. But for normal rust? Perfect.

Yes, all lithium batteries degrade slightly over time. But here's the real number:
Realistic Degradation:
Year 1: Zero noticeable degradation (100% performance)
Year 2: About 5-10% loss (89-95% performance - you don't notice it)
Year 3: About 15-20% loss (80-85% performance - still great)
Year 4+: 25-35% loss (65-75% performance - you start to notice it)
What this means in practice: Year 1-2: Battery lasts 90 minutes, maintains full power. Year 3: Battery lasts ~75-80 minutes, 95% power. Year 4-5: Battery lasts ~65-70 minutes, 85% power.
Even after 4 years of heavy use, it still does 100% of the job in a single cookout. It's not a situation where it suddenly stops working in year 3.
If you want to maximize battery life:
Don't leave it discharged to 0% for days (it degrades faster).
Recharge to 80% instead of 100% when possible (this adds 6-12 months of life).
Do not expose to extreme heat (direct sunlight for hours is not ideal).

Works Perfectly On: ✅ All standard commercial grills (Weber, Traeger, etc.) ✅ Homemade grills (as long as the grates are "normal") ✅ Vintage cast iron grates ✅ Custom flat griddles (Blackstone-style) ✅ Locally crafted grills
It may NOT work 100% on: ⚠️ Grills with very close grates (<5mm gap) ⚠️ Grills with very uneven or "corrugated" surfaces (the rotating head doesn't make even contact) ⚠️ Fully enclosed grills (like smokers/pans where you can't access the grates from above)
If you order and it's found to be incompatible: Full refund within 48 hours (don't wait 90 days). This is not a win-win situation for us.

Robot Grill Cleaners ($300-500): ✅ Pros: Automatic—turn it on and forget it ✅ Pros: No physical effort ✅ Pros: Spectacular to watch (trust me, it's fascinating)
❌ Cons: Heavy (~2-3 kg), difficult to store ❌ Cons: Battery degrades VERY quickly (2-3 years max) ❌ Cons: Doesn't reach ALL corners (round head vs. rectangular surface) ❌ Cons: They have bristles (same shedding problem they're trying to solve) ❌ Cons: Costs 5X more ❌ Cons: More limited warranty ❌ Cons: If the motor breaks, it costs $80-120 to repair
Our Product ($44,99): ✅ Pros: 1/5 the cost ✅ Pros: Reaches EVERY corner (180° rotating head) ✅ Pros: Lightweight (480g vs. 2-3 kg) ✅ Pros: Battery lasts 4-5 years of heavy use ✅ Pros: Super-cheap brush heads if they wear out ($14.90) ✅ Pros: Total control—YOU decide where to clean and how much ✅ Pros: Faster (5 minutes total vs. 10-15 minutes with a robot)
❌ Cons: Requires 5 minutes of manual effort ❌ Cons: Not "automatic"
The Real Truth: If you have the money and want automatic at all costs, a robot is for you. If you want the BEST VALUE, performance, universal compatibility, and don't mind 5 minutes of movement? Our product wins 9 out of 10.

You can use it in BOTH situations.
On Hot Grills (ideal):
Wait 5-10 minutes after you finish cooking (grates are still warm)
The grease is still soft—easier to remove
Less cleanup time (3-4 minutes vs. 5)
BETTER overall result
How to Do It: Put the meat down. Wait for it to finish cooking. Remove the meat. Turn on the brush and clean WHILE the grates are cooling. Finish cleaning, it finishes cooling—perfect.
On Cold Grills (OK, but not ideal):
Still works great
Takes 1-2 minutes longer
The grease is more "crusted" so it requires more pressure
But the brush still cleans it (100% effective)
Brush Safety: The heads and motor are designed to withstand temperatures up to 60°C (140°F). You won't burn the brush even on very hot grills.
Real Advice: Clean warm = better results, less effort, faster process. Clean cold = still works, just a little slower. There's no "wrong answer"—it depends on your preference.

Yes, it makes noise. No, it's not a neighbor problem.
Actual Noise Level: ~75 dB (equivalent to a household vacuum cleaner, a blender, or a shower)
Comparison:
Whisper: 30 dB
Normal Conversation: 60 dB
Our Brush: 75 dB
Drill: 90 dB
Motorcycle: 100+ dB
Usage Timeline: Turn on the brush = 5 minutes of noise. Finish = total silence.
It's short and not a piercing noise (it's not a diesel engine). It's a "buzz" that isn't really annoying.
Real Test With Neighbors: One of our customers in London used the brush at 5:00 PM in a garden shared with 6 other residents. No one complained. He said the noise from his barbecue was MORE annoying.
If You're Paranoid: Use the brush during normal hours (8:00 AM - 9:00 PM). No one will say anything.
If You Use It At 10 PM: Yes, the neighbors will probably notice. But for five minutes? They're unlikely to formally complain. If they do, you're being a bit rude, and it's not the brush's fault.

It depends on the coating.
Safe Coatings (100% Protection): ✅ Porcelain-coated (most common) ✅ Stainless steel ✅ Cast iron (obviously) ✅ Carbon steel ✅ Ceramic coatings
Questionable Coatings (Proceed With Caution): ⚠️ Teflon/PTFE (non-stick type) — Technically possible, but not recommended because you could wear down the coating ⚠️ Chrome-plated (vintage) — Works, but the brush head may scratch slightly over time
The Real Problem: If you have grill grates with very delicate coatings, you shouldn't even use a traditional brush. The problem is the type of grill, not our brush.
If You're In Doubt: The brush head is SOFT enough that it won't damage even the ceramic. You can test it on a small area. If it feels OK, you'll be fine.
Honesty Moment: The only coating we'd absolutely say NO to is the non-stick Teflon type (like pans). But who owns a grill with that kind of coating? Almost no one. It's rare.

Performance remains stable for ~1,000+ uses. This is what we tested.
Realistic Timeline (Heavy Use 3-4 times/week):
Months 1-3 (12-15 uses): Performance: 100% Speed: 5 minutes Power: Maximum
Months 4-8 (40-50 uses): Performance: 99% Speed: 5-5.5 minutes Power: Maximum (you don't notice it)
Months 9-15 (70-90 uses): Performance: 95-98% Speed: 5-6 minutes Power: Maximum (still perfect)
Months 16-24 (120-150 uses): Performance: 90-95% Speed: 5.5-6.5 minutes Power: Slightly reduced (but still excellent)
After 6 months of heavy use: Head: Will likely need a replacement (they last 3-4 months = normal, buy a replacement for £14.90) Battery: 97% of original capacity (you don't notice it) Motor: Works like the original Day One
After 12 months of VERY heavy use (180+ uses): Head: On yet another replacement (normal wear) Battery: ~90% capacity (still lasts 85 out of 90 minutes) Motor: Zero failures, works perfectly
The Key Point: It's not like phones where it suddenly "expires." It's a gradual and very slow decrease that you don't even notice for at least 6-8 months.
Maximum Test Usage: One of our testers used the prototype 5 times a week for 6 months (130+ uses). Result: Zero problems. Head slightly worn (normal). Battery at 96%.
