Lubing Brifter Levers?

Hello All,
I have a Trek 1.2 that has Shimano Sora STI, 9 speed levers. I've only used the bike one season but thinking maybe I should add some lube to the levers. New to brifters so I'm not sure if this is good practice or not. For lube choices (in the house at the moment) I have silicone, wd-40, Boeshield t-9.
What would be the preference,if any, and is it as simple as pulling back on the lever and giving the parts a spray?
Thanks

Are they not working ? if not then use WD-40 , let dry then add a light oil . If they are working I would just leave them until there is a problem .

They are greased as they are assembled .. years down the road the grease deteriorates ,
but not so fast as one year.

Leave them alone.

If they go wonky, like they are hanging up on a downshift or won't release on an upshift (rear), then blast them out with WD-40 from a bunch of different angles until things are smooth and clicky again, and then goop them up with T-9.

You should have gone through a few sets of cable and housing before you need to lube your brake/shift units.

Why do you think they need lubrication?
Is it the brake or shift mechanism?
I would check the brakes and derailleurs to see if they are binding. You can manually move the derailleurs a little (to slacken the cables) and pinch the brakes to make sure they move freely. Make sure that cables/housing have not been kinked.
I make it a habit of doing a little light winter maintenance by hitting all of the brake and derailleur pivot points with a tiny amount of light oil, running through all of the gears and playing with the brakes a few times and then wiping away the excess oil with a paper towel. (and also giving the whole machine a good cleaning). And do an over all assessment to see if there is any rust/corrosion, especially if you rode in the rail or wet conditions.

I'm not familiar with those brifter, but if you can remove the hoods, do that before any lubrication. Some plastics/rubber materials do not like some oils. I dislike WD-40 for this reason.

I just use thin spray grease. Makes the action smoother, and it it thins out any grease that may be gumming up inside.

Nothing is wrong with the levers. Just wasn't sure if they should be treated like brake pivot points or chains where adding lube from time to time is a good thing. Thanks for the replies.

shifters stay pretty clean unless you are a nasty sweater. leave it be until the grease dries up or you crash the shifter into the mud

Many STI shifters have been restored to good operating performance after a WD40 treatment as mconlonx has described in post #4 . But I agree with the others that there is no reason to perform this before problems arise unless the shifters become internally water wet. As we all know, WD stands for water displacement.

I totally agree that you should probably not do anything. If you live in a desert with a lot of blowing sand that might be different but short of that one year should make no difference. Having said that, when I've cleaned brifters I remove them entirely, take off the hood and spray clean them with ... White Lightining (if I remember the name)...it totally strips all grease and evaporates. Then I spray with WD40 and allow it to dry and then I brush in grease.
