Problems with dust in the Mamba Elite

So I have a Mamba Elite wired mouse and have been using it for the past two years, and over time enough dust has accumulated on the inside of the mouse that it's causing the scroll wheel to be erratic and will cause me to double scroll or scroll in the opposite direction that I'm scrolling in with each tick. I'm pretty certain dust buildup is the reason for it, but the compressed air I bought for cleaning hasn't helped me get the dust out of the inner workings of the mouse, and the Mamba Elite doesn't seem to have any way to actually open it to get better access to where the dust buildup likely is. Is there any good way to solve this issue? It's becoming really annoying and buying a new mouse just to fix an issue of dust doesn't seem like a wise decision.
