Premium grease by Chemours, great for lubing both linear and (with care) tactile switches, and stabilizers.
Only a very thin application is required – 1 ml should be enough to lube 100 switches. Overlubing is a common beginner mistake and results in a “mushy”, sluggish switch feel.
If you’re inexperienced with switch lubing, you might want to refer to this great article on KeebTalk.
Available in jars of 3 ml (~6 g), 5 ml (~10 g) and 10 ml (~20 g).
