TL,DR: powder laundry detergent is better than the liquid one.
When it comes to choosing laundry detergent, I used to default to liquid detergent because powder would often clump together. However, I recently learned that liquid detergent has a bigger environmental impact - it contains microplastic particles that are hard to remove in wastewater treatment plants, and it’s also less efficient at cleaning. Plus, liquid detergent usually comes in plastic bottles, whereas powder detergent is often packaged in plastic film or even cardboard. So, I switched back to powder detergent. To avoid clumping issues in my humid laundry room, I found a simple solution: I use an old fork to break up the powder before use. It’s a small effort, and I’m happy to be reducing my pollution footprint a bit.

I used to do borax, washing soda, and zote. I went back to liquid detergent because it seemed like all of my clothes were kind of dingy. The reason I seem to remember is something about enzymes.
Enzymes help but a lot of detergents also have a UV dye that makes clothes look whiter.
This is really handy for Halloween decorations because you can make your bathroom look like a murder scene with a blacklight
