I use Felco pruners, they are not stainless steel.
Once I am through using them for the day I strip them down, clean them, sharpen them and reassemble, then they are oiled.
It is fine to use alcohol exclusively, if you make sure it stays on for at least 30 seconds.
I built a bottle holder for my belt for the bleach
water, it has a rubber cover with a slit so it doesn't spill and is still easy to plunge the pruners into it. The rubber acts like a squeegee as they are pulled out.
I've used the same pruners since 1973, they are still going strong.
