these are concise notes for fellow beginners who are interested in switch lubing, but not sure how and where to start. just remember that like anything in mkb modding, it's all about personal preferences. as long as you like the outcomes, it's all good.
the main purpose of switch lubing is to make switches relatively smooth when you type on them. for instance, most stock switches, e.g. cherry mx switches, are scratchy when they are new. (i.e. the sandy feel when keys travel from top to bottom, and vice versa) to improve smoothness, lubes are applied at various contact areas in a switch to get rid of frictions. however, depending on the type of lubes, and amount applied, this also brings changes in typing feels and sound.
i hope the following can give better ideas on selection of lubes, and how much to apply them on your switches. still, it's better to experiment first hand with a few, before you apply them to the rest of them.
1. thick vs. thin lubes. - the terms 'thick' and 'thin' are used to refer to viscosity of oil or grease. thick means high viscosity (e.g. to me it's krytox gpl 105/205 and above), while thin means low viscosity (e.g. krytox gpl 103/203; singer oil) - if you were to preserve as much as the original typing feels and sound, use thin lubes. thick lubes will change typing feels and sound considerably, but it's really effective for sound dampening.
2. oil vs. grease. - for relatively easier applications, use oil. however this doesn't mean it's very hard to apply grease on switches, e.g. for low-viscosity grease like 203, it's as easy as oil. as usual, practice makes perfect. - use oil paint brush to control the amount applied. - some lubes can be mixed safely, e.g. krytox gpl. the mixtures can achieve certain viscosity that you want (103/107), or to make grease easier to apply (e.g. 105/205)
3. less vs. more. - in general, less is more. - excess can cause lube fart, and 'stickiness' when you type.
4. cheap vs. expensive. - this usually translates to the shelf life of a particular lube. usually cheaper lubes will cost much less (e.g. super lube grease, singer oil), but its shelf life is also way shorter than expensive ones (e.g. krytox gpl) - cheap lubes sometimes also leave residues behind when they wear off. (e.g. super lube grease will leave white residue behind) however, imo it's easy to clean them up. - this doesn't mean cheap lubes are bad choices (e.g. super lube grease or singer oil are very economical) it depends on options that allow you to reapply them if necessary. (especially when the lubing effects are worn off) if you have a modular board, or permanent builds that support switch top removal, or plateless, you can still opt for cheap lubes.
5. unlubed vs. prelubed switches. - these days there are also prelubed switches, e.g. kailh box or pro switches. they're smooth by default. additional lubing is pointless. - for these prelubed switches, the only part that requires lubing is their springs, if you wanted to bring down the noise level. (usually i use 105 for this)
6. always use plastic-safe lubes to avoid damaging your switches.
all in all, switch lubing is a task that requires patience. however with a good set of tools (e.g. compatible switch openers, good-quality oil paint brush), you can speed up the process considerably. imo it's worth the efforts.
edit:
as for the amount that you should get, usually 5ml is more than sufficient for a full-sized board, leaving you a little extra. also note that i use krytox gpl series as reference most of the times, mainly because the series consists of oil and grease with different viscosity, and they are relatively easier to obtain than before.
imo the minimum is to get 103/203 (thin), and 105/205 (thick), this allows you to get better ideas on how viscosity affecting application, typing feels and sound.
