The process can be intimidating, but you can achieve spotless results using the right hacks.

Let's Get Started!

1. Use Warm Soapy Water to Clean BBQ

Professionals recommend washing your barbecue grill with safe, effective products. Make sure you carefully scrape off stubborn stains when the BBQ appliance is still hot. You can use a wire brush to get rid of loose dirt and grime.

Once the grill has cooled down, use a mild dishwashing soap and warm water for cleaning. If grease and grime won't budge, use this method.  Spray the solution onto the affected area, then gently scrub with a brush. This will help dislodge carbon deposits from grates and grills.

Make sure you rinse and dry immediately to prevent rust stains. Once dry, rub a vegetable oil on the grill using a lint free cloth.

2. Burnt It Off to Dislodge BBQ Grease

This is one of the most effective methods to restore your BBQ like a pro. Large BBQs are difficult to wash. If you have a gas barbecue, turn the burners to high once you've grilled your food and heat it for 10 to 15 minutes. This technique will burn off food particles over a high heat until charred. This will help you kill lethal germs and bacteria with ease.

Next, rub the cooking surface with half an onion to remove stubborn stains or burnt on food particles. This won't leave scratches behind.

3. Submerge Greasy Grates Using White Vinegar

Professional end of lease cleaning Sydney experts recommend using white vinegar to clean greasy BBQs. Instead of scrubbing the machine abrasively, you can apply a vinegar and warm water solution to remove stains. It is one of the best non toxic cleaning agents for a spotless shine.

The acetic acid in vinegar can break down grease, grime and stubborn carbon deposits without causing any damage. You can scrub with an old toothbrush for an effective result.

You can also sprinkle a generous amount of caustic soda to achieve spotless results without causing damage. Ensure you rinse and dry to prevent streaks.

4. Clean Hot Plates and Burners the Right Way

Disconnect the gas BBQ and remove the burners, bars and metal plates. Gently scrub the surface with a soft bristled brush to remove food residue and grime. Next, wipe the burners and plates clean with a warm water and vinegar solution. Ensure you check the burner tubes for spider eggs and other germs.

5. How to Degrease BBQ Grills with Baking Soda

Baking soda is one of the most effective and versatile cleaning agents that can help you remove stains, grease, and gunk without leaving scratches behind. Here's how you can do it:

  • Mix baking soda and warm water to make a thick paste.
  • Apply it over your greasy BBQ grates and grime laden areas for 20 minutes. This will break down the grease
  • Use a brush or sponge to gently scrub the area
  • Wipe the grates with a damp cloth
  • Dry the grill before using it again.

6. Steam Clean Your Filthy BBQ

A steam cleaner is one of the most effective cleaning tools that can banish stains, grime, and grease without causing any damage to the surface. You can use a soft bristled brush attachment to remove heavy grease from nooks and crannies. The hot steam will break down food particles and burnt residue from nooks and crannies, especially on stainless steel.

7. How Often Should You Clean BBQ?

You should always deep clean your grates and other marks at regular intervals to prevent moisture and germs buildup. Clean it before the grilling season to ensure a healthy, hygienic Barbecue experience. You can hire experts for a professional oven and BBQ cleaning Sydney to pass your rental inspection when moving out of your rental home.
