While drain cleaner is a staple for shower drains and kitchen sinks, using it in a toilet is a different beast entirely. In fact, it is one of the few DIY plumbing moves that can turn a $10 problem into a $5,000 disaster.
Squirt a generous amount (half a cup) of liquid dish soap into the bowl. Let it sit for 10 minutes. The soap acts as a lubricant, sliding past the clog. Follow it up with a bucket of hot (not boiling) water poured from waist height. The gravity and pressure often clear the jam. drain cleaner for blocked toilet
Toilet clogs are usually (and sometimes "flushable" wipes, which are a lie). Drain cleaners are designed to dissolve hair and grease . They are not particularly good at dissolving a wad of wet paper or a foreign object like a toy or a cotton swab. While drain cleaner is a staple for shower

If that chemical hits the water and reacts violently, or if the plunger slips, you risk splashing lye or acid onto your skin, eyes, or clothes. These burns happen instantly and are severe. Plumbers have horror stories about rushed ER visits caused by DIY drain cleaner mishaps.
