Cure for Carbon Lock?

[Harpoon1]

I just started using Superlative Arms gas blocks. According to them, using the “bleed off” function requires no maintenance! Yes, I’m dubious of that claim too! Anyway, surely it’s a maintenance item regardless and a few drops of oil and exercising the screw after every session does help.

However………after some neglect and becoming stuck……….this may help!

Having said that. Worst case, I would remove the gas lock and put it in a sonic cleaner with that solution. For ever how long it took!
