How to clean iron grills on a cooktop.

This is going to be a “part one” and “part two” blog post because it started off with me wanting to clean the barbecue grills and ended up with me cleaning the cast iron grates on our gas cooktop.

One worked better than the other, but I’m going to chalk that up to the longevity of the grease and grime that was present.

You take your greasy, burned-on-food, gunky cooktop grates,

put them, as they are, into a large garbage bag, 

Clean your iron burners and grills

along with some ammonia,

(Just put the dish as is – don’t rub the ammonia on the grates.  It’s the fumes that are going to do the work for you.)

seal the garbage bag with grates and ammonia dish inside – and make sure it’s air-tight.

Leave in the sun for 12-24 hours.

Make sure you do this project outside.  The sun heating up the garbage bag really makes the ammonia fumes strong.

Be careful – when you do open the bag back up, there is going to be a large waft of fumes – very dangerous to inhale.

Take your grates to the sink and gently wipe down and dry.

No scrubbing necessary!

Gorgeous dahling!

As a side note, if you’re itching to clean your grates and it isn’t sunny out, or you want to clean them in the winter, heat up your oven to about 200 degrees and put your iron grates inside. 
Turn the oven off and put the dish of ammonia inside as well.

No peeking!  You want to keep those fumes working on the grates, so keep the door closed overnight.

The next morning you should be able to easily wipe off all of the grime AND you can wipe down the inside of the oven for a double-whammy of easy cleaning!

Check back tomorrow to see how this process worked on our barbecue grills.

Have a great one!

      You said I needed more cleaning posts, so I was forced to battle the ultimate in grunge. Tomorrow it’s my BBQ – UGH!

      Looks great can’t wait to try. Now please tell Me how you cleaned the black stove part under the grates. I have the same gas cooktop you do and can not get it clean like yours.

      If there is stuff really baked on, I use ENJO marble paste. It’s so fine that it scours without scratching – it really is brilliant. In between I just wipe down with a kitchen ENJO and water. Promise – this ENJO stuff is unbelievable!

      Contact Lynn directly if you want to buy – if you’re in Canada, it will save you the shipping

      Ammonia cleaners are SO bad for your respiratory system–If you have ENJO, you can use it on the grill and stove grates too!

      I concur completely. Having said that, I do have to show some posts with alternate methods – not everyone has jumped on the ENJO bandwagon (yet), and in posting other tricks and tips, I can encourage a broader audience to the blog – and hopefully they will learn about ENJO in the process.

    Thanks for sharing this pressure cleaning option of grill. I think electric brush is may not be reliable option. I have spiral design Grill Brush and that works pretty well. It is also very helpful in cleaning of warm grill because of long tail.

      I’ve never heard of a grill brush – I will definitely be looking into it though. Thanks for taking the time to comment!
