The Homestar Plus cleaning products sold at Daiso are typically designed for general cleaning tasks, such as wiping surfaces, cleaning floors, or kitchen counters. They are not specifically formulated for clearing clogged drains or sewers. If you're looking for a product to help with drain cleaning, you might want to consider a product that's specifically designed for that purpose.

For clearing drains and sewers, it's better to use products like:

1. Drain Cleaners: These are specifically formulated to break down grease, hair, soap scum, and other debris that clog pipes. Common types include liquid drain cleaners, gel-based cleaners, or foaming solutions.

2. Plunger: A good old-fashioned plunger can work wonders for unclogging drains in sinks, showers, and toilets.

3. Mechanical Drain Snake: This tool can physically reach deep into pipes to remove blockages.

4. Baking Soda and Vinegar: A natural remedy for minor drain clogs. Pour baking soda down the drain followed by vinegar, and let it sit for 15-30 minutes before flushing with hot water.
