How do I remove the yellow discoloration caused from smoke damage on porcelain sinks and bathtubs?
Simple cleanser and scrub pads should clean them well unless the finish has become porous and the smoke is trapped in the finish. Porcelain is very hard and non-porous, making it easy to clean. In that case it's best to look into refinishing of the items. www.integritycoatings.com is a good place to research this.
