Krytox GPL 205 G0 Lubricant Grease with Brush for Linear/Tactile Switches (10 Grams) Review (2026)

What Krytox 205g0 is

Krytox GPL 205 grade 0 is a synthetic grease widely used across the mechanical keyboard hobby for lubricating switch housings, stems and springs, and it has become one of the most common recommendations for anyone starting to lube their own switches. It is a thick grease rather than a thin oil, so it is best applied with a small brush to spread a thin, even layer rather than being dripped or sprayed on. The grease is rated for a wide operating temperature range and is described as nonflammable and chemically stable, which is part of why it has become a default choice among keyboard builders rather than a repurposed automotive or bicycle lubricant.

What is included in this listing

This particular listing packages 10 grams of the grease together with a small brush, so buyers do not need to separately source an applicator before they can start lubing switches. The brush is the standard small, soft-bristled tool used to apply grease into switch housings, onto stems, and along stabilizer wire contact points without needing a syringe or more specialized tools. Ten grams is a relatively small quantity by weight, but because only a thin film is needed per switch, it is generally enough to lube a meaningful number of switches for one or more keyboard builds rather than being a single-use amount, making it a reasonable size for a first-time buyer testing the process.

Which switches it works best on

This grease is intended for linear and tactile switches, along with stabilizers, rather than clicky switches. Linear switches benefit from lubing because it smooths the stem's travel through the housing and reduces scratchy feedback, while tactile switches can have their tactile bump feel refined depending on how much grease is applied and where. Stabilizers benefit heavily from this type of grease since it reduces the rattly, hollow sound that unlubricated stabilizers are known for on keys like the spacebar, shift and enter. Applying this grease to clicky switches is generally avoided by the hobby because it can dampen or soften the click bar mechanism that gives those switches their signature audible click, muting the effect the switch is designed to produce.

Using it effectively

Lubing switches is a manual, somewhat time-consuming process that involves opening each switch, typically with a switch opener tool not included in this listing, then brushing a thin layer of grease onto the stem rails, the inside of the housing, and the spring before reassembling. Applying too much grease can be counterproductive, since excess grease can pool, attract dust, or dampen the switch's responsiveness rather than improving it, so a light, even coat is generally the goal. Because this process is applied switch by switch, lubing a full keyboard's worth of switches takes patience, and it is worth budgeting time for the task rather than expecting a quick five minute job, especially the first time through.

Value for the hobby

As one of the most recommended switch greases in the mechanical keyboard community, this product carries a strong reputation, and getting the grease bundled with a brush removes one extra purchase for anyone assembling their first lubing kit. It represents solid value for hobbyists who plan to lube multiple keyboards or who want a reliable, well-regarded grease rather than an unproven off-brand alternative. Buyers should still plan to separately source a switch opener if they do not already own one, since this listing covers the grease and application brush but not switch disassembly tools, and should confirm their switches are linear or tactile rather than clicky before applying it.
