How do I unblock a toilet?

Drain cleaners are mostly for hair and grease clogs. The best way to unclog a toilet is with water and/or with a plunger, which you can buy from any hardware store such as Wilkinsons.

Get a bucket of water and pour it into the toilet bowl. If this doesn’t work you will need a plunger on hand and you should be able to plunge the toilet until the water flushes away.
