How to clean your stainless steel Cookout BBQ

Stainless steel as its names suggests 'stains less than steel' and needs to be cleaned regularly to prevent tea staining (a brown discolouration that forms on stainless surfaces) and rust.

Stainless is protected by a thin layer of chromium oxide. When dirt, salt and grease build up on this coating, it does not work properly and can lead to corrosion. Consistent upkeep and cleaning of your stainless BBQ is a necessity to keep it looking its best.

What type of stainless are our BBQ's made from?


Our Australian made BBQ's are manufactured from high quality stainless steel.

The outer body and lid are built from 316 marine grade stainless and the BBQ plates from duplex stainless.

Please find below a guide on how to clean your Cookout BBQ and keep it in good condition.

External cleaning


The exterior lid and underbody of the BBQ should be cleaned or wiped down regular to prevent tea staining and to prolong the high finish of the stainless steel.

Washing the BBQ with warm soapy water can help to remove general contamination found in the air such as dust, dirt and salt.

Silicone based polished are ideal when applied to the external surfaces, on the outside of the lid, body and underbody of the BBQ. Silicone based polish will help the stainless form a protective layer that will prevent tea staining and rusting.

Apply and work the polish with a soft cloth then remove the polish with a second clean soft cloth.

If your BBQ was manufactured prior to 2015 then the gas control may need to be oiled / greased regularly to prevent it from becoming jammed or ceased (later model BBQ's have the addition off a stainless shroud and rubber grommet to protect the controls from ceasing). Remove the gas control knob by lifting up. Apply a small amount of lubricant grease around the shaft of the control, where it enters through the top of the control box. This will prevent the control from taking in water and corroding.

To further protect your BBQ we recommend using our specially designed, locally made, water resistant BBQ cover. Made of high grade Nylex, which is a PVC coated polyester and UV treated material our covers are water resistant, highly durable, available in 3 colours and designed to be used with our Classic and Deluxe BBQ ranges.

If you are looking for a storage solution we also offer BBQ bags.

External cleaning guide

  1. Fill a bucket with warm water.
  2. Add a good amount of soap and stir to mix.
  3. Use a soft cloth or sponge moistened with the soapy water to wipe down the external surfaces of the BBQ.
  4. Follow the grain of the metal as you clean.
    • For a more detailed clean, the lid should be removed by undoing the screw on the right-hand end of the plate. Lift the right-hand end of the lid up and push to the left. Once the lid is removed turn upside down, depending on the amount of grease use soapy water or spray a liberal amount of oven cleaner and let sit for 10-15 minutes, before hosing down. Be sure to remove all excess grease from the front and back gutter on the inside of the lid.
  5. Rinse completely with clean water.
  6. Dry with a soft towel. Do not allow the external surface to remain wet.
  7. Apply and work the silicone-based polish with a clean soft cloth.
  8. Then remove the polish with a second clean soft cloth.
  9. Check fat cup or drip tray. If necessary, remove, empty then return. If your appliance is an Infinity Grill BBQ be sure to replace fat absorbent material.
  10. Now to oil / grease the gas control (on 2015 models or earlier). Simply remove the gas control knob by lifting up.
  11. Apply a small amount of lubricant grease around the shaft of the control.
  12. To finish return the gas control knob.
  13. Don't forget to use your BBQ cover or bag.

Cleaning the BBQ plate


After cooking and while the BBQ is still hot, pour a small amount of water onto the BBQ plate and scrape excess burnt food off with a BBQ scraper (it's easier to scrape off while warm).

Oven cleaner may be applied to the BBQ plate when it has cooled, spray a liberal amount onto the plate and let sit for 5-10 minutes. If the BBQ has stubborn black stains a green or blue Scotch-Brite may be used. Then wipe off with a cloth to remove any excess fat and grease. Be sure to read the oven cleaners manufacturer's instructions before using.

To remove stubborn burn marks or blackening that remain after cleaning the plate, mix a small amount of white vinegar and water together, pour on the plate then work onto the surface with a Scotch-Brite pad. This can produce quite a strong odour if applied while the plate is hot so be careful not to be positioned over the plate while doing. This will help to bring the BBQ plate back to its original finish.

Please Note: Blackening / burning of the stainless plate is normal when using the BBQ.

BBQ plate cleaning guide

  1. While BBQ is still hot pour small amount of water onto BBQ plate.
  2. Scrape excess burnt food off with a BBQ scraper.
  3. Once plate has cooled apply oven cleaner and leave for 5-10 minutes.
    • Be sure to read the oven cleaners manufacturer's instructions before using.
  4. Wipe oven cleaner off with a cloth to remove excess fat and grease.
  5. If your plate still has burn marks or blackening mix a small amount of white vinegar and water together.
    • Blackening / burning of the stainless plate is normal and cannot be prevented when using the BBQ.
  6. Pour on the plate then work onto the surface with a scouring pad.
  7. To finish wipe away any excess vinegar.

A few DO NOT's


  • DO NOT use steel wool. Steel wool is generally made from carbon steel and will damage the stainless surface leaving it prone to rusting.
  • If using an abrasive pad make sure it is a green or blue Scotch-Brite or similar product. Be sure to rub the pad in the same direction of the grain to achieve a uniform finish.

Failure to properly maintain your BBQ will void all warranty.
