P21S Polishing Soap 300g | Metal Polish for Exhausts & Bare Metal

P21S Polishing Soap: metal polish in a soap cake. Lather it on, rub it in, rinse it off.

P21S says it removes corrosion and brightens stainless steel, aluminium and chrome. The tub lists exhausts, bumpers, fuel tanks, wheels, running boards and diamond plate. On modern cars, only use it where those parts are bare or chrome metal, such as chrome bumpers or uncoated polished wheels, not where they're painted or clear-coated. It comes with its own applicator sponge. Made in Germany.

How to use

1. Make sure the surface is cool, then wash off any dirt and oil.
2. Test on a small, hidden area first.
3. Wet the sponge and wring it out until it's just dripping.
4. Drag the sponge across the soap cake a few times, then squeeze it to make a lather.
5. Rub the surface vigorously.
6. Rinse thoroughly with water, or let it haze and buff it off with a soft cloth.
7. Rinse the sponge and let it dry before putting it back in the tub.

Not for

P21S says it isn't intended for painted or anodised surfaces, and that includes clear-coated parts. Our supplier also advises against using it on titanium-finish exhausts.
