Limescale buildup in your toilet not only looks unsightly, but it can also reduce the efficiency of your toilet and cause other plumbing issues. Thankfully, it's not too difficult to tackle limescale buildup and get your toilet looking as good as new. Start by pouring a cup of white vinegar into the toilet bowl and letting it sit for a few hours. Then, scrub the limescale away using a stiff-bristled brush. To finish the job, you can use a toilet bowl cleaner or descaling agent, making sure to follow the instructions carefully. You can also create your own descaling solution by mixing together white vinegar and baking soda, and then scrubbing the limescale with a brush or sponge. Keep in mind that the process may take multiple attempts, so don't be discouraged if your toilet isn't sparkling clean the first time around. With some elbow grease and the right tools, you can remove limescale from your toilet in no time!
