Etymology
錆 combines 金 (metal) with 青, which likely contributes the sound and may have originally suggested a blue-green patina or tarnish on metal. The exact historical development is uncertain.
Meaning mnemonic
Metal 金 that turns the color of blue-green 青 is rusting. Picture a copper roof developing a green patina: that is 錆, rust and tarnish.
Reading mnemonic
For ショウ, imagine a rusty old car that you need to show to a mechanic: show -> ショウ, and the rust is the reason you're showing it.
