Reducing keyboard rattle - making mechanical keyboards more mellow

Noisy space bar? Loose shift key? Rattling Enter key? Many keyboard noise problems are caused by stabilisers.

These are metal bars in plastic housings that ensure even pressure across larger keys. Because they are made for a variety of keyboards, the tolerances can be pretty loose and many aren't lubricated. A spot of dielectric grease in the right place can make an enormous difference to the sound (and feel) of your keyboard. Even if you can't remove the stabilisers, you can probably lubricate them enough to make the difference. Even non-mechanical (rubber dome or membrane) have stabilisers that benefit from a bit of lubrication.

Examples of dielectric grease: Permatex is the most popular brand. https://www.amazon.co.uk/Permatex-22058-Dielectric-Tune-Up-Grease/dp/B000AL8VD2/ There are other brands like Loctite https://www.amazon.co.uk/Loctite-Dielectric-Tune-Up-Grease-80-milliliter/dp/B003XZFIF6/ Krytox GPL 205 is the fanciest choice among keyboard snobs https://www.ebay.co.uk/itm/Krytox-GPL-205-High-Performance-Pure-Fluorinated-Synthetic-PFPE-PTFE-Grease-5g/293836963782

Whilst dielectric grease is great for your stabilisers, it's a bit thick for inside your switches. It is good for the internal springs - it really takes the ping out of them - but you need a milder grade like Krytox GPL 105 for the slider inside a switch. ... https://www.youtube.com/watch?v=Cn4LqrCR_2k
