Each type of detergent - liquid, powder, and pods - offers different benefits. Laundry powder tends to contain bleach, which is great for maintaining the brightness of white fabrics as well as removing some stains. However, bleach can cause some bright colours to fade. Liquid detergents and pods don’t contain bleach, so colour fading over time isn’t as much as of an issue.
Laundry powder delivers the lowest cost per load, while pods tend to be more expensive but offer the greatest convenience.
