Buyer’s Guide

From scent to amount, here are some of the top factors to consider as you’re searching for and purchasing dishwasher detergent.


Dishwasher detergent comes in liquid, powder, gel, or tablet form. Tablets are pre-measured and ready to place in the detergent compartment of your dishwasher. While convenient, they’re more expensive than the other types. The remaining three each have their own benefit, with powder scrubbing, gel degreasing, and liquid shining your dishes.


Some detergents come with a fresh scent, such as lemon or citrus, to make your dishes smell clean when you pull them out. Others are unscented or chemical-smelling. If you’re sensitive to smells, opt for a detergent with a light scent or no scent.


Many dishwasher detergents are starting to use more eco-friendly ingredients. Using plant- or mineral-based formulas, they avoid phosphates, dyes, and other harsh chemicals. Some detergents are also packaged in recycled or recyclable materials, such as cardboard.


The number of tablets or the number of ounces of detergent you have determines how many times you can run your dishwasher. Most tablets come in packs between 50 and 100, while liquid, gel, and powder detergents typically come in bottles or packages that hold around 40 or 50 ounces. Sometimes multiple bottles are packaged together to give you more detergent at a more affordable per-ounce price.

Items You Shouldn’t Wash in a Dishwasher

We can all agree that washing dishes in a dishwasher is more convenient than doing it by hand, but there are certain items that aren’t safe for your dishwasher. Here are some items that you have to clean in your sink:

  • Nonstick pots and pans
  • China
  • Wooden dishes
  • Crystal dishes
  • Insulated glasses
  • Copper pots and pans
  • Aluminum cookware
  • Chef’s knives
  • Hand-painted dishes
  • Graters
  • Labeled or printed dishes

Frequently Asked Questions

How much dishwasher detergent do I need to use?

If you’re using tablets, use one per load. For gel, powder, or liquid detergent, measuring it can be more tricky. Typically, two or three tablespoons per load is sufficient, but you may need more or less depending on how many dishes you’re cleaning, what type of stains are on them, and how effective your dishwasher is.

Can I use dishwasher detergent to wash my dishes by hand?

No. Detergent doesn’t suds well, and it can irritate your skin. Conversely, you shouldn’t use dish soap as a replacement for detergent either, as it can overflow or flood your dishwasher.

Why aren’t my dishwasher pods dissolving fully?

There are several reasons your pods may not be dissolving, but two of the most common ones are that your dishwasher isn’t getting hot enough and that your detergent door is blocked. Both of these problems have easy fixes. You can change the wash cycle or rearrange the dishes, respectively.
