I'm wondering if anyone can help with this.
I recently had a new bathroom installed with gold plated fittings (shower, taps etc.). You are not supposed to use standard cleaning products on these as they can damage and strip the gold finish. Instead, you use diluted dishsoap/washing up liquid and you can also buff with a soft dry cloth. I have tried this, my cleaner has tried it, and it does't work.
Almost from day one, the shower valves especially were covered in watermarks that won't come off and make them look dirty. I have exactly the same style of shower in another bathroom in chrome, which is years old but never has this problem because it's cleaned with normal bathroom cleaners.
I called the manufacter to ask what they would recommend and they said either the diluted dishsoap or diluted white wine vinegar. So, I tried the latter as well. Didn't make any difference. I bought a gold polishing cloth (the kind you use on jewellery). That didn't work. Neither did a microfibre cloth for cleaning chrome.
I've heard suggestions to use Brasso or Silvo but the manufacturer said absolutely NOT to use that. In fact, they wouldn't recommend anything other than washing up liquid or dilued vinegar. A lot of the suggestions I've found online are for removing tarnish from gold and that's not the problem.
Any suggestions that have been tried and tested? This is the fitting that's showing the water marks the worst and how it looked when new and unused. It does not look like that now!
