So, how did we get to this point? Years ago, washing machines used a lot of water, and detergent was designed to work with that excess water. But as technology improved, and high efficiency washers became more popular, detergent manufacturers had to adapt. They created new formulas that would work with less water, and that's where liquid detergent came in.
Now, you might be thinking, "But I've always used powder detergent, and it's worked just fine!" And that's great, but the thing is, powder detergent can leave behind residue and deposits in your high efficiency washer, which can cause problems down the line. It's like using the wrong type of fuel in your car - it might seem like it's working, but it can cause damage in the long run.
