Can you clean brass with ketchup?

Yes, you can clean brass with ketchup.

• How it works: Ketchup contains mild acids that help break down the tarnish (the dark, oxidized layer) on brass.
• Usage: Apply a thin layer of ketchup on the brass, let it sit for a few minutes (usually between 5 and 10 minutes), then gently rub the surface with a soft cloth before rinsing with water and drying thoroughly.
• Effectiveness: This method works best on lightly tarnished brass items. For heavily tarnished pieces, repeated applications might be needed or a more specialized brass cleaner may be more effective.
• Precautions: Always test the ketchup on a small, inconspicuous area first to ensure it does not damage any plating or delicate finishes. Avoid prolonged exposure as the acid might eventually affect the finish if left too long on some types of brass.
• Aftercare: Once cleaned, buff the brass gently to restore its shine, and consider applying a light protective coating to slow down future tarnishing.
