I poured drain unblocker (Mr Muscle Drain Unblocker Gel) too quickly into my kitchen sink yesterday evening and it spilled over, and left a white mark around the drain (corrosion?) I am not worried about optics, but could this be a continuing health hazard from residual chemicals?

I rinsed it thoroughly with water and treated the stain first with vinegar and then baking soda today, but would really appreciate some advice. Many thanks!
