First, it is important to identify the cause of the blockage. This could be a build-up of soap scum along with hard water deposits and other items that have been flushed down the toilet bowl or in some cases hair may cause obstruction which needs clearing.The next steps involve using plunger and/or auger for unblocking toilets depending on how severe it has become as well as using rubber hangers (wire coat hanger) but this method can damage porcelain so exercise caution when attempting this step at home without any prior plumbing experience! Additionally, you can use baking soda mixed with hot water poured into the toilet bowls - allowing them time to clear away potential blockages before flushing again afterwards if needed; blocked toilets cannot always be cleared by just plunging alone.
