Oven trays often end up with stubborn, burnt-on stains that seem to become more entrenched with each use. This can leave the baking tray looking discoloured and dirty, and can even create an unsanitary environment for cooking. While it may often seem like your tray is beyond salvation, there’s a natural product that's a favourite among cleaners but remains under the radar for many of us.

When it comes to natural cleaning products, the combination of vinegar and baking soda usually takes centre stage. However, there's another option that works wonders on oven trays: liquid soda crystals.

Recently, @thecleangroup shared a video on their Instagram page offering a “professional cleaner's burnt-on baking tray secret” that involves using “no chemicals” and “no scrubbing”.

The video was captioned: “I’ll be honest, this one blew me away. I thought there was no saving this tray.

“Meet the unsung hero of kitchen cleaning. It’s a chemical-free product that no one is telling you about.

“It shifts the wildest of kitchen grime and demolishes burnt-on grime faster than other methods. What is it? Liquid soda crystals. No one will believe you didn’t just buy a new one.”

To try this cleaning tip, you'll also need one cup of baking soda. Start by sprinkling the baking soda onto the tray.

Next, add half a cup of liquid soda crystals and fill the tray with boiling water. Set the tray on the hob and ignite a low heat. Let it simmer for 30 to 40 minutes (until you notice the most affected areas beginning to lift).

Afterwards, the tray was rinsed, effortlessly washing away all the accumulated grease and grime.

The jaw-dropping results left cleaning enthusiasts in the comments astonished, many hadn't realised the powerful potential of liquid soda crystals.

@jonesydoeshome exclaimed: “What a great result! I never think to use soda crystals.”

@mummycleans declared: “I need to get some soda crystals now.” @rabiassaeed commented in awe: “Wow looks like new.”

One curious user queried whether liquid soda crystals would be equally effective on air fryer baskets, to which the experts replied, “Absolutely”.
