    Recommendations when cleaning a cast iron barbecue

    When you want to clean the cast iron barbecue of your home, it is recommended that you follow these tips:

    • Always wear gloves and a mask , even if you are not going to use toxic products. It is better to work safely than with fear that you may burn or inhale something toxic.
    • Do not use products that you would use to clean a pan or dishwasher product . This does not serve to clean the cast iron barbecues.
    • When you cook with the barbecue, if you want to avoid problems when cleaning it, avoid liquid fuels . Although they help the barbecues light up before, then it costs more to clean.
    • When removing the ash, you do not have to get rid of it . The ash is very good for cultivation, and is sometimes used as a homemade trick to clean barbecues in poor condition.
    • Before starting to clean the barbecue, take it outside. Do not clean it inside a garage or a closed environment . It is better to be outdoors.
    • Clean the grill and barbecue separately . It is not the same to remove the fat from the grill than from the barbecue.
    • Ideally, the barbecue could be dismantled, to be able to occupy only the area of ​​the embers separately. Also, it is good to do a review of the pieces from time to time, cleaning them well at least once a year.
    • It may be that the cast iron barbecue you bought can withstand the environmental changes, but that does not mean it's good that you're outdoors all the time. If you are not going to use it, buy a cover for barbecues or disassemble it to keep it in the box , until you have to use it again.
