Key steps:

  1. Ideally, you should try to clean your barbeque as soon as possible, when it is still warm.
  2. A pressure washer is a handy tool to blast the interior of your BBQ with.
  3. Remove burnt-on ash with a pumice stone or oven scraper.
To prevent food sticking to the grill, before you barbecue wipe the grills with cooking oil. This will make cleaning up after cooking a lot easier!
  • Blast the interior of the barbecue with a pressure washer.
  • For lidded barbecues, moisten an old newspaper and place it inside the barbecue. Replace the lid, and apply a gentle heat underneath. This can generally be achieved with a couple of small pieces of lighted wood, but make sure the paper inside does not catch fire – this will only add to your problems!

The grime on the inside should have loosened and now you can set about removing it:

  1. Using your pumice stone or scraper, gently but firmly go over the inside, making sure to remove all of the tough dirt. If the barbecue is enamel-coated, be extra careful not scrub too hard, as this will damage the integrity of the material.
  2. Shake out or remove the dislodged dirt.
  3. Using your BBQ cleaner, thoroughly sluice down the inside of the barbecue.
  4. Use a bleach spray like Domestos  to sanitise the grill and utensils you used. Rinse clean.

Do not expect the area where the coals sit to get perfectly clean – some permanent damage will always develop here. Just make sure it is free of any obvious removable waste material.

Use biocides safely. Always read the label and product information before use.

Cleaning the outside of a BBQ

Any guide on how to clean a BBQ would not be complete without reference to cleaning the outside. This is pretty easy to deal with:

  1. Wipe down the outside of the BBQ with a moist cloth and if anything is stuck to the surface, consider using a solution of baking-soda and warm water to remove it.
  2. If your barbecue’s exterior surface is made of stainless steel, think about wiping it down with oil to weather-seal it.
