If a tablet claims to remove hard water deposits, mold, mildew, or detergent residue, that is usually a plus for me.
Cleaning Power
The main reason I buy these tablets is for cleaning power. I prefer tablets that break down buildup effectively and leave my washer smelling fresh. I pay attention to whether the product is designed to remove limescale, soap scum, and odor-causing residue. A tablet that works in one cycle is especially convenient for me.
Ease of Use
I like cleaner tablets that are simple to use. Usually, I want to drop a tablet into the drum and run a cleaning cycle without any extra steps.

Odor Removal
One of the biggest reasons I use washing machine cleaner tablets is to get rid of bad smells. I look for tablets that target mildew, musty odors, and trapped detergent residue. A fresh scent is nice, but I prefer a product that truly neutralizes odor instead of just masking it.
