What's the best way to just clean the pistons? How can I expose them? My thoughts were to give them a light smear of red brake grease.
I remember years ago, on a cg125, just squeezing them partly out with the brake lever and forcing them back in by tightening a G-clamp!  :015:
 The brake and clutch fluids are clear and I don't wish to change them at the moment but just want to give the calipers a bit of a spruce up.

Ended up just cleaning everything with a clean cloth!  :mfrlol:
Stay between the hedges!

What I usually do is remove the calipers from the rotor, leave the pads in, and squeeze the lever... then remove pads.  This exposes them enough to clean with brake fluid and a toothbrush/cloth.  Then I rinse with isopropanol.  I don't use brake cleaner or harsh solvent that would potentially harden the piston seals.
Put the pads back in and pry them apart to retract the pistons.
