Specialized Stain Remover for Bathroom Oil/Resin Stains

The mention of a 'Clove oil stain on bathroom sink' highlights a common problem: difficult stains on household surfaces. While clove oil might be specific, a powerful, multi-surface stain remover designed specifically for common bathroom stains, particularly oil-based, resinous, or difficult-to-remove ones, would appeal to a broad market. The lack of comments suggests that readily available solutions might not be common knowledge.
