Cleaning my kitchen is not something that I look forward to – especially the stovetop and surrounding area.

Yes. I should keep up with it and wipe it down on a daily basis.

But the reality is that life gets in the way.

When I finally get around to cleaning the stovetop – well, let's just say it's a little bit greasy.

Thankfully, cleaning the actual surface isn't too bad – but those stovetop grates are another story entirely.

The Problem With Cleaning My Stovetop Grates

A great way to clean stove grates for a gas stove (no pun intended!) is to soak them in your sink with a bit of dishwashing liquid.

My stovetop grates before cleaning. Not magazine worthy, but oh so realistic.

Then scrub them down with a stiff brush, and you should be good to go.

But this method doesn't work for me.

You see, I have a Bosch dual fuel range that I love.

It has 5 burners and three long cast iron grates that go from the front of the stovetop to the back of the stovetop.

Unfortunately, the grates are longer than my sink – so soaking them is out of the question.

I have tried holding them vertically, scrubbing them down with a kitchen scrubbie, and then using the sink hose to spray them off.

Basically I ended up with a huge puddle on my counters and still sticky stovetop grates.

My Solution for Cleaning These Large Stove Grates

The best solution for cleaning these long stovetop grates – for me – was to put them in the dishwasher.

If you decide to try this, check the manufacturer instructions for cleaning your particular brand and model of burner grates.

Some manufacturers specifically say NOT to wash the stove grates in the dishwasher – like this article states on the Sub-Zero site.

However, I did mention that my stovetop grates are LONG – and you guessed it, they did not initially fit into my dishwasher.

Nothing is ever easy, right?

How to Fit Long Burner Grates Into Your Dishwasher

Well, it turns out that this problem was not too hard to solve.

My dishwasher – which is also a Bosch – has a removable top rack.

I had never taken it out before because I have a sort of philosophy that if something is working well, don't change it.

The racks in my dishwasher were working well for me in their current set up. So, I was pretty hesitant to go and pull that top rack out.

But I finally got so annoyed at trying to clean my burner grates in my too small kitchen sink that I finally buckled down and did it.

Um. Can you believe that it was really easy – both to take out and put back in?

Yeah. I should have done it sooner.

Anyhow, with the top rack removed I was able to fit the long cast iron burner grates on the diagonal on the bottom rack in an empty dishwasher.

I simply run a one hour cycle and – boom! – clean burner grates.

Since they are cast iron, I make it a point to take them out of the dishwasher immediately after the cycle is done and dry them off completely. so they don't rust.

Use Your Judgment

I cannot stress enough that you should use your judgment and read the cleaning instructions that came with your stove – contact the manufacturer if you can't find them.

For me, my first choice would have been to soak them in the sink.

But since this wasn't an option – since the kitchen sink was too small, washing the large stove grates in the dishwasher was a solution that I was comfortable with.

I suppose I could soak them in the bathtub – but that is really pushing it. Cleaning the kitchen is already hard enough!

The Best Time to Clean Your Stovetop Grates

To state the obvious – cleaning your large burner grates in the dishwasher will be easiest to do when your dishwasher is empty.

So, you don't necessarily need to clean the stovetop grates at the same time that you clean the rest of your kitchen.

The best time to do this is right after you empty your dishwasher.

Just some food for thought.

  1. If your grates do not have rubber feet cushions attached to grate itself (like my GE Cafe ) the manual says to put in oven on the racks as you do self clean mode … works amazing I do my burners too in there ! Read your manual

  2. Hello,

    Good idea! I have been told before this can be done. Do you use any dishwasher detergent? Or let the hot water do the work?

    Thank you


  3. Thx for the tip.
    Did you put detergent in the dishwasher load? Or just let it run for an hour by itself?
    Thank you!

    1. Thank you for your question. I have done it both ways – but I have to say that I am reluctant to use detergent each time. Many manufacturer’s do NOT recommend to wash iron grates in the dishwasher – so you should absolutely check the manufacturer instructions for your particular appliance.

      Ultimately, you have to do what you are comfortable with. When the grates on my stove get too greasy I will use detergent, otherwise just a water wash seems to do the trick.

      Recently, I also wash them in the sink – but since I can’t soak them (the sink is too small) I use a stiff dishwashing brush with handle and a few drops of Dawn to scrub them down as they rest on a diagonal in the sink – if that makes sense.

      I hope that helps!
