We have vanity sink in that i can see small patches of faded colour how to fix that please suggest
Welcome to the Bunnings Workshop community @dvedekar. It's wonderful to have you join us and many thanks for your question on sink repair.
It would really help members give you accurate advice if we could see the issue you’re dealing with. If you’re able to upload a few photos, that would be great. Let me know if you need a hand doing that.
Also, could you clarify exactly where the fading is? Is it on the cabinet (like a melamine surface) or on the sink bowl itself (for example, a vitreous enamel or ceramic basin)? It would also be useful to know when you first noticed the marks and whether anything might have caused them.
From your description, if the patches are inside the bowl, it can sometimes be caused by certain personal care or cleaning products sitting on the surface and lightly bleaching or staining it. Once we can see a photo, we’ll be able to give you a much clearer idea of what’s going on and how to fix it.
Please let me know if you have any questions.
