Toilet deodorizer blocks, also known as urinal or toilet blocks, are products used to help maintain cleanliness and freshness in restroom facilities. They typically come in solid block form and are designed to dissolve slowly in water, releasing fragrances and sometimes active ingredients that neutralize odors and prevent bacterial growth. Here are some types, names, and common uses of toilet deodorizer blocks:

Use: Commonly used in urinals to mask odors with a distinct smell. They are effective but less environmentally friendly.
PDCB-Free Blocks:

Composition: Made without paradichlorobenzene.
Use: Provide odor control without the harsh chemicals of traditional para blocks, often using alternative fragrances or active ingredients.
Enzymatic Blocks:

Composition: Contain enzymes that break down organic matter responsible for odors.
Use: Useful in restrooms where organic waste odors are a concern, offering a natural and effective way to control smells.
Gel Blocks:
