Shimano 10s brifters stopped in the cold ...

Waaaa! He used a name thousands of people use but not the exact model designation from Shimano.

Sorry, I'll try to refer to them as Shimano Total Integration or as ST-7800 in the future. Oh wait, no. No I won't.

I use Finish Line Cleaner and Lube, silicon base. Resurrected many a shifter.

I believe that is the product recommended by Shimano. Seems I remember that from a training video.

All shifters, MTB or road, get flushed as part of the service.

For my personal bikes, I remove the hoods, flush with above, then dribble in some Dumonde Tech liquid grease. Good stuff. Work the shifters to coat evenly.

Liquid wrench a little too much for this application.

A can of Finish Line spray cleaner and lube should be part of every riders home tool kit.

Are you talking about speed degreaser or 1 step spray?

Finish Line 1 Step

Simply great stuff

I used Sea Foam Deep Creep penetrating oil rather than WD40 followed up by aerosol tri flow lube. No problems now with my 7800s in the cold.

With 6700 shifters.
I'm thinking about flushing with brake cleaner (probably Muc-Off's) and re lubing with 15W/40 (Tune recommended this for lubing my hub, so i have a whole half gallon now)

Anyone care to pitch in or keep me from doing a terrible mistake?

Shimano 600 downtubes in the winter for me.

This is what my local swears is the magic sauce to cure this issue.
A bit pricey.

LPS is great stuff.

Coincidentally, this past weekend I went to work on a DA7800 equipped bike that hasn't been shifted in ages. Sure enough, levers stuck. I ended up grabbing this off the shelf (vs. WD-40; I wanted to try something different that had lube & corrosion inhibitor in one). It did the trick.
