How to Clean the Rim Jets on a Toilet Bowl


Over time, you might notice that your toilet isn’t working as well as it used to. In due course, toilets can become slow when flushing, which causes problems in completely removing waste from the toilet bowl with just one flush. 

In most cases, this can be due to a clog, root-infested pipes, or an issue with the flapper. However, a commonly overlooked cause of a slow-flushing toilet is clogged rim jets. 

The rim jets, located under the rim of your toilet bowl, are responsible for distributing water during flushing. Over time, mineral deposits (limescale) and debris can accumulate, hindering their effectiveness and compromising the cleanliness of your toilet, leading to unhealthy conditions.

In this article, we'll guide you through simple yet efficient steps about how to clean toilet rim jets, ensuring a powerful water flow, efficient flush, and a cleaner toilet bowl.
