Works for some I'm sure, but not for me - I kinda feel like water is the enemy. I sometimes think many folks these days are a little too obsessed with cleaning the INSIDE of their games. Personally I like whatever shows to the player to be as shiny and clean as possible, and internal parts that affect game operation, but wire looms and other brackets and plywood only get cursory cleaning...
But to each their own fershure...I just feel like shining up internal parts are a waste of MY time - other's are free to feel differently, but I just have too many games to restore! Frickin' hoarders....lol
