These two products sit on opposite ends of the same job. One is a set of silicone replacement feet that keeps your air fryer tray sitting properly and protects the interior surface. The other is a spray cleaner built to dissolve the greasy mess that builds up after cooking. If you searched "how to clean air fryer," you probably want the second one — but a surprising number of people actually need the first, because a damaged or missing tray foot is often what makes cleaning feel impossible in the first place.
• GSZN 8PCS biggest strength: Eight food-grade silicone rubber feet that protect the inside of your air fryer from scratches and keep the tray stable — rated for heat up to 430°F / 221°C.
• GSZN 8PCS biggest trade-off: This is a replacement part, not a cleaner. It does nothing about grease. It also only fits trays that match its size, so you need to measure before buying.
• Rewjug 2-in-1 biggest strength: A concentrated 110ML spray degreaser plus a towel and sponge, designed to dissolve baked-on residue on baskets, racks and trays with minimal scrubbing.
• Rewjug 2-in-1 biggest trade-off: It's a consumable — you use it up and buy more. It cleans surfaces but doesn't fix worn or missing hardware.
• Who GSZN 8PCS is for: Anyone whose air fryer tray feet are torn, lost or scratching the coating, and who wants a direct replacement.
• Who Rewjug 2-in-1 is for: Anyone whose air fryer works fine but keeps getting greasy, and who wants a spray-and-rinse routine instead of soaking and scraping.
The GSZN 8PCS is a pack of eight silicone rubber bumpers for air fryer trays and grill plates. The material is the whole story here: food-grade silicone, BPA-free, non-toxic and tasteless, and heat resistant up to 430°F / 221°C. That temperature ceiling matters, because air fryer interiors run hot and a cheap rubber foot will harden, crack and fall off. Silicone holds up far better than that.
The job it does is small but real. Those little feet lift the tray slightly off the bottom of the basket, keep it from sliding, and stop metal-on-metal contact from scratching the non-stick coating. When one tears or goes missing — which happens, especially if you scrub aggressively or run the tray through the dishwasher — the tray starts scraping. Over time that scraping is what turns a smooth non-stick surface into a patchy, food-catching mess that no spray can fully fix.
Installation is straightforward: you press the silicone pieces onto the tray, and they come off easily when you want to clean them. The package is eight tabs, so you have spares rather than a single replacement.
Buy it if you've noticed your tray wobbling, rattling, or leaving scratch marks — or if you've lost a foot and want to get ahead of the problem before the coating suffers. Skip it if your air fryer is running fine and your real issue is grease. Also skip it if you haven't checked the fit: these are sized for Instant Vortex, COSORI and Dreo air fryer grill plates, or any fryer tray that matches the stated dimensions. Measure first, because a size mismatch means they won't seat properly.
Rewjug's 2-in-1 is a spray cleaner and degreaser aimed squarely at the part of air fryer ownership nobody enjoys. The pitch is simple: spray the foam onto the grease, let it sit a few minutes to break down the grime, then rinse with warm water. No heavy scraping, no endless soaking.
What makes it worth a look is the surface safety claim. It's engineered for non-stick coatings, ceramic, stainless steel and glass — the exact materials air fryer baskets and racks are made from. That's the thing people worry about most when cleaning an air fryer: whether the cleaner itself will degrade the coating they're trying to preserve. A degreaser that's too aggressive can strip or dull a non-stick lining, and once that's gone you're stuck with a sticky basket forever. Rewjug positions itself on the gentle-but-effective side of that line, which is the right instinct.
It's also multi-purpose. The 110ML concentrated formula is listed for air fryer baskets, racks and trays, but also oven liners, microwave interiors, grill grates and toaster ovens. So it earns its shelf space beyond a single appliance. The kit includes a premium towel and sponge alongside the spray, which means you're not hunting for a non-scratch pad the moment it arrives. It's unscented, which I appreciate for a product you're using around food surfaces.
Side-by-Side: Which Should You Choose?
• Best for protecting your air fryer's coating → GSZN 8PCS. Silicone feet physically stop the tray from scratching the interior.
• Best for removing baked-on grease → Rewjug 2-in-1. A dedicated degreaser beats dish soap on burnt residue.
• Best for a one-time fix → GSZN 8PCS. You install it and it stays; nothing to reorder.
• Best for an ongoing routine → Rewjug 2-in-1. It's a consumable, so you'll replace it as you use it up.
• Best for heat resistance → GSZN 8PCS. Rated to 430°F / 221°C, which is what you want inside a hot appliance.
• Best for multi-appliance use → Rewjug 2-in-1. Works on ovens, microwaves, grill grates and toaster ovens too.
• Best for a no-guess purchase → Rewjug 2-in-1. No sizing to match; just spray and rinse.
• Best if you own an Instant Vortex, COSORI or Dreo → GSZN 8PCS, provided the tray dimensions line up.
If you're asking "how to clean air fryer" because your basket is greasy, I'd buy the Rewjug 2-in-1. It directly addresses the mess, it's safe for the coatings that matter, and the spray-sit-rinse method is the least painful way to deal with baked-on residue.
But if your tray rattles, wobbles, or is already scratching the inside of your fryer, I'd buy the GSZN 8PCS first — because no cleaner fixes a coating that's being worn away every time you cook. In my opinion, the smartest move is the GSZN feet to protect the surface, and a degreaser like Rewjug to keep it clean. If you can only pick one, pick based on whether your problem is damage or dirt.
FAQ
Spray a degreaser onto the basket, racks and tray, let it sit a few minutes to break down the grease, then rinse with warm water. Rewjug's 2-in-1 is built exactly for this three-step routine and is formulated to be safe on non-stick, ceramic, stainless steel and glass.
how to clean air fryer heating element
The data sheets here don't cover heating-element cleaning, so I won't guess at a method. What I can say is that the GSZN silicone feet are rated to 430°F / 221°C, which tells you these air fryers run hot enough that you should never spray liquid directly onto a hot element. Let the unit cool first.
how to clean air fryer with baking soda
Baking soda isn't part of either product's instructions, so I can't speak to it from these data sheets. Rewjug's stated method is spray, wait a few minutes, then rinse with warm water — and since its formula is designed to dissolve grease on its own, you may not need a DIY paste at all.
