I have rust starting from seemingly behind a shower fixture. Possibly something I did, but possibly some rust that was bound to happen eventually.

What's the first step in a situation like this? It hasn't gotten much worse since it got to this stage, but of course rust always gets worse. I was recommended to scrub the area with a limescale/rust remover solution but I think the fixture has to come off, then a scrub down/sandback and then seal again somehow.

  • Hello, and welcome to Home Improvement. What is the surface material that the fixture is mounted in? – Daniel Griscom Jan 29 at 1:47
  • I can't tell exactly but it seems like ceramic tiling. – insidesin Jan 29 at 2:08

First to clean it there are several commercially available cleaning products that are based on mild acids. One such is caller "CLR" (for Calcium Lime and Rust) which is not an endorsement, just an example. If the tile is ceramic, it should not harm it. Once the rust stains are gone, you should focus on why something is rusting. I can't tell from the photo what that fixture is. A grab bar of some sort? Was it designed to be mounted in a shower area? if so, it must have been cheap because they used steel, which will ALWAYS rust eventually. Sometimes people put a chrome plating on it to make it appear nice, but that never lasts. It also could be that you mounted it with steel screws, a no-no in a shower, and they are rusting BEHIND that device to where the rust is just leaking out. Either way, whatever is steel in there must be replaced with something that is brass or stainless steel, otherwise it will just happen again. When it is rusting, it is also failing and will eventually just break off.

  • It's the bar that supports the holder for the shower head handle. Would CLR penetrate to behind the fixture though, where it's originating? Perhaps let it soak in a little and rinse well? Thanks for your advice! – insidesin Jan 29 at 4:04
  • CLR is great and will eliminate the rust quickly but it will be back unless sealed or proper materials used.+ – Ed Beal Jan 29 at 16:40
  • Ed Beal is right, it's like taking cough syrup; you can control the symptom temporarily, but the root cause remains. All the CLR will do is remove the stains from the other surfaces, it will not cease the rusting process, in fact it may accelerate the corrosion. It is a mild acid. – JRaef Jan 30 at 2:33
