Hi everyone im in need of some help I have just recently purchased a Gillette slim adjustable off ebay from the Razor emporium guys. its very nice looking but there are some issues. The blade tray will not move it is stuck i cannot get it to go up or down. Also the adjustment knob moves but not very easily . I have heard of people letting there razors soak in hot water for a couple hours to fix problems like this, is that what i should do? Any info on how to fix this razor would be greatly appreciated because I was intending to gift to my brother to introduce him to wet shaving.
