The Ultimate Guide to Solid Soap For Dishes - Remove the Toughest Stains Everytime

Looking for an eco-friendly alternative to liquid dish detergent? Solid soap for dishes is the answer! Find out why it’s a win for your health, wallet, planet, and the dishes.

Shampoo and conditioner bars are probably on your radar by now, but what about solid soap for dishes?

Ditching plastic bottles and watered-down formulas goes beyond the bathroom. Solid dish soaps are emerging as a plastic-free alternative to liquid dish detergents. They’re made from natural ingredients, last longer, and leave little waste - that’s a win for your health, wallet, and the planet!

Now, you might be thinking that sounds too good to be true…do they actually work? 

At Earth Hero, we’re huge fans of solid dish soap, and in this post we’ll give you the 101 on how to make the most of them so they’ll work on even the toughest of stains. We’ll share some options to choose from, and if you’re still not sure, some more sustainable liquid options to try instead.

Right, it’s time to tackle our (eye roll) favorite chore…

Why Switch To Solid Dish Soap?

If you’re used to liquid dish detergent a solid bar seems strange, but trust us, there are so many reasons to make the switch.

Here are just a few:


Humans produce one million plastic bottles every year. Solid dish soaps are just one way to reduce toxic plastic waste, as they come in recyclable packaging and dissolve to eventually leave no waste.

Natural Ingredients 

Many liquid detergents contain ingredients that might be harmful to human health, for example, artificial fragrances, phosphates, and SLS (Sodium Lauryl Sulfate). Made by conscious brands, most solid soaps contain natural and non-toxic ingredients.  

Concentrated Formulas 

You know what makes liquid detergents liquid? Water! Solid bars cut that out, so you’re only paying for active ingredients that work to remove stains.

Longer Lasting

Because of their concentrated formula, solid dish bars last way longer than their liquid counterparts. They can last as long as 3 bottles! 

Lathers Up And Cuts Grease

You won’t sacrifice cleaning power when you switch to bars. They’ll lather up in the water like regular dish soap, and cut through grease and grime. 


One cool thing about solid dish soaps is that they can be Cleaning Chameleons and adapt to different needs - wiping surfaces, washing hands, and spot-cleaning stains.

Soon you’ll be a bar-convert! 

How To Use Soap For Dishes

Want to give bars a go but aren’t sure how?

It’s best to check the instructions that come with the specific bar you choose, that said, here’s how it generally works:

  1. Scrape food residue from your plates and give them a quick rinse. 
  2. Wet your desired dish sponge or brush. 
  3. Scrub the sponge/ brush on a block to lather up. 
  4. Start scrubbing your dishes until they’re squeaky clean. 
  5. Rinse well. 
  6. Allow your dish soap bar to dry out completely on a soap shelf or soap rest so that it’ll last longer.

Scrape the plates. Scrub the bar. Scrub the dishes. Rinse and dry. It’s as easy as that!

And since the natural ingredients don’t dry out your hands like normal liquid detergents, you shouldn’t need to wear plastic clothes either.

First, try letting the dishes soap in piping hot water for 30 minutes or so, before using your dish bar as normal. You might want to try a tougher scrubber like these:

Not done the trick? The next step is to grate a little bit of the bar into your dish and give it a swill so it dissolves quickly. After another 30 minutes, scrub your dishes again. That should do it!
