Hiya I moved into a new flat a little while ago and the shower has started spraying water everywhere and sometimes water not even coming out of the holes. I know that this is limescale buildup and I need to clean it. I have severe ocd and worry about jobs I’ve never had to do before plus chemicals etc. I think the shower head can be unscrewed but I’m worried that this will be a messy job. Can anyone give me any tips and encouragement to get this job done please?
