Liquid detergents are generally recommended for washing in hard water. This is because the ingredients in liquid laundry detergent are less likely to react with hard water minerals. Liquid detergents also rinse more easily than powder in hard water, so they're less likely to leave residue behind.
Liquid detergent is better for your washing machine. It does not usually clog your machine and doesn't cause your clothes to stain. In fact, liquid detergent also doesn't fade your clothes. Powder detergents often contain bleach which is damaging to your clothes.
Both work pretty similarly for regular, lightly soiled clothes (everyday laundry). Powder tends to work better for dirt/mud stains, and liquid is better for grease/oil stains. For more heavily soiled clothes from working out, liquid is better, esp in HE machines.
If you wash a load of laundry without detergent, the clothes will not be effectively cleaned. Detergent contains surfactants, which are chemicals that break up grease, stains, and food residues and disperse them in water (1).
If I'm doing an easy load that doesn't require any extra care, I'll toss in pods. For items that come home dirtier than usual, it's time for a tougher bio detergent probably in pod form. For anything that requires a gentle or handwash cycle, then a liquid detergent customized for silk or wool is a must.
With pods, if you have an extra-large load of laundry, you might need to use two — and that can get expensive if you do a lot of large loads. On the flip side, if you have a small load of delicates, you're limited to the amount of detergent already in the pod, which is likely too much.

Grated Bar Soap and Borax
Regular bar soap can be grated and combined with Borax to create a very effective laundry detergent alternative. Here's how to do it: Using a butter knife, a spoon or even a cheese grater, grate about a cup of bar soap. Add the grated bar soap to ½ cup of borax and ½ cup of washing soda.
Dish soap can cost much less than laundry detergent and can clean your clothes just as well. However, it's important to keep in mind that you will use a lot less dish liquid than laundry detergent. Adding too much dish soap will cause your washing machine to overflow with bubbles.
Plastic Packaging: Liquid detergents typically come in plastic bottles, which can create more plastic waste compared to cardboard boxes. Less Effective on Certain Stains: Liquids might not be as effective as powders when tackling heavy-duty stains like mud.
Remember, fabric softener is completely optional, and your garments will likely pop out of the dryer feeling fresh, clean, and soft without it. However, “For some, it might make doing their laundry a little more fun to use an extra product that smells very good and is colorful,” Fulford says.
Liquid detergent can go into the drum with no problem, but this should be avoided with powder. Adding powder to the drawer ensures it will dissolve before hitting your clothes to prevent powdery marks and white stains. Adding it to the drum may result in an uneven wash and oily residue.
Powder detergents are especially efficient at removing stains like dirt, clay, and mud, says Jennifer Ahoni, the director of scientific communication for North America fabric at Procter & Gamble. Liquid detergents, on the other hand, are great at dealing with grease and body soil, Jennifer says.
Using regular detergent in an HE washer produces too many suds. This could potentially lengthen the wash cycle, affect cleaning action or overflow the machine.
As with dishwashing liquid, shampoo can be used to substitute laundry detergent in an emergency. It's great for handwashing and a go-to option if you're traveling and only have a sink at your disposal.
Laundry Detergent Is Specifically Designed to Clean and Protect Fabrics, but Dish Soap Is Not. Laundry detergents are specifically made with the ingredients necessary to get clothes clean and protect fabrics to keep them looking their best.
Use Laundry Borax or Baking Soda
If you have no detergent at all, use 1 cup of borax or baking soda for a normal load. Pretreat stains before washing and use the warmest water temperature recommended for the garments.
A common combination of DIY washer fluid includes distilled water, rubbing alcohol, and liquid dish soap. In some cases, a few drops of blue food coloring is thrown into the mix to achieve a look that resembles commercial washer fluids.
But our tests of dozens of laundry detergents show there are significant differences from one formula to the next. Some detergents are effective at getting clothes clean while others barely clean better than running a wash cycle using nothing but water.
Liquid Detergent Leaves Behind Less Residue
Even if hard water isn't an issue in your home, liquid detergents are less likely to leave residue on clothes and linens than other formulas. It's possible that pods and sheets won't fully dissolve in the washer, creating stubborn detergent stains on fabrics.
Powdered Detergent Cons
More difficult to use for pretreating stains. Must be stored in a dry area to prevent caking. Does not dissolve well in extremely cold water leaving white residue on fabrics and in the washer. The fillers in powdered detergent can build up in septic systems and cause clogs.
