"After experiencing spike pedal input, I took my G27 apart to clean the potentiometer.
Tools needed: Phillips screwdriver, 2.5mm hex wrench, 4mm hex wrench, 10mm flat wrench, electrical contact cleaner, cloth/towel.
Guide used: http://www.gtplanet.net/forum/threads/spiking-pedals-fix-clean-your-logitech-g25-g27-pedal-pontentiometers.247510/ (only cleaned the housing and the pot, never thought of taking potentiometer apart).
Good as new after cleaning.

前段时间玩游戏，总是有很多输入脉冲，导致赛车游戏基本没法玩了。所以就把 G27 炒掉，清洁里面的电位器。
所需工具：十字螺丝刀，2.5mm、4mm内六角扳手，10mm六角套筒，电子设备清洁剂，毛巾。
参考文档：http://www.gtplanet.net/forum/threads/spiking-pedals-fix-clean-your-logitech-g25-g27-pedal-pontentiometers.247510/ （只清洁了托架和电位器，从来没想过拆掉电位器，怕手残把这个最重要的部件弄坏了）。
清洁完成后，这东西就跟新的一样了。"
