What are the best metal cleaning poultices?

Metal cleaning poultices are highly effective solutions for removing rust, tarnish, and stains from various metal surfaces. Whether you're restoring antique tools, polishing silverware, or maintaining industrial equipment, the right poultice can make all the difference. Here are some of the best options:

1. Baking Soda and Water Paste – A simple yet powerful DIY poultice for light rust and tarnish. Mix baking soda with water to form a thick paste, apply to the metal, and let it sit before scrubbing gently.

2. Vinegar and Flour Poultice – Ideal for stubborn rust stains. Combine white vinegar and flour to create a sticky mixture, spread it over the affected area, and leave it overnight for deep cleaning.

3. Commercial Rust Removers – Products like Evapo-Rust or Naval Jelly offer ready-to-use solutions for heavy-duty rust removal without harsh chemicals.

4. Lemon Juice and Salt – A natural abrasive for polishing copper and brass. The acidity of lemon juice combined with salt’s grit helps break down oxidation.

5. Clay-Based Poultices – Bentonite clay mixed with a solvent like acetone is excellent for drawing out deep-seated contaminants from metal surfaces.

For best results, always test the poultice on a small area first and follow up with proper sealing or waxing to prevent future corrosion. Regular maintenance with these poultices will keep your metal items looking pristine for years.
