What is dishwasher detergent?

Dishwasher detergents are water-soluble cleaning products made specifically for washing dishes in a dishwasher. There are three main types: tablet, powder and gel.

  • Tablets are small blocks of concentrated dishwashing powder that are put in the dispenser, or simply placed in the main dishwasher area.
  • Powder can be poured or scooped into your dishwasher dispenser. It might be a better choice if your home has smaller washing needs and doesn’t require a full tablet.
  • Gel is similar to dishwashing liquid used for washing dishes by hand. It can be poured into the dispenser and is usually the middle ground between powders and tablets in terms of pricing.
ProsCons
Tablet
  • Most efficient
  • Usually includes a rinse aid to help minimize spots
  • Comes in pre-measured amounts
  • Helps reduce time spent soaking and scrubbing
  • Usually more expensive
  • Only comes in one size, so there’s less flexibility for different loads
Powder
  • Cheapest option
  • Effectively removes stains
  • Lasts a long time before needing replacement
  • Adjustable dosages
  • Can be abrasive for delicate tableware, including glass
  • If overused, dishes may get a powdery residue
  • Loose powder can be hazardous for those with kids or pets
  • If not stored properly, can be activated by water
Gel
  • Slow-pouring gel is easier to control than powder
  • Easier than powder to clean if spilled
  • Water-based composition is less abrasive on tableware
  • Works instantly and does not need time to dissolve
  • May leave spots or a light film on dishes
  • More product is required than when in tablet form

How to compare dishwasher detergent

Dishwasher detergents can range from $0.05 per wash for the cheapest home brand powder, up to $0.94 per wash for premium tablets.

Consider these factors when choosing the right type and brand for you:

DIY dishwasher detergent alternatives

Several DIY detergent alternatives are also available. They’re typically compatible with most dishwashers, but may not perform as well as the commercial formulas. Keep in mind that using certain ingredients could void your dishwasher warranty. Check yours before trying a new DIY detergent.

When trying a DIY alternative for the first time, test a small batch first. The effectiveness of the formula can vary depending on your individual dishwasher and the type of water in your house.

Commonly used DIY dishwasher detergent ingredients include:

  • Borax
  • Baking soda
  • Vinegar (during rinse cycle)
  • Salt
  • Citric acid
  • Essential oils for fragrance
  • Grated soap
  • Baking powder
  • Lemon juice
Keep in mind that if baking soda is used regularly, its grittiness could wear away prints on tableware and older china. Also, vinegar can eventually damage the rubber in your dishwasher and, if mixed with salt, can cause discoloration in metal tableware and pans.

3 tips for making dishwasher detergent more effective

  • Keep detergent fresh and dry. Store your detergent in a container away from moisture to prevent lumps. Only pour it into a cup when you’re ready to run a cycle. When powder detergent gets lumpy, throw it away.
  • Use the right amount of detergent. Using the correct amount is important if using powdered or liquid detergent that is not pre-packaged.
  • Determine how hard your water is. Depending on whether your water is soft or hard, your dishwasher will need a different amount of detergent for peak performance and to avoid damaging your dishes. As a rule of thumb, harder water needs more detergent. You can find out how hard your water is by checking your state/council website or by asking your water company.

Bottom line

Using the right dishwasher detergent can help you get squeaky clean dishes without having to scrub and soak them first. Compare different types to suit your washing needs and preferences.
