New DSA Dolch on my CM Storm - squeaky backspace fix?

[notbrain]

What can I do to get rid of a nasty squeak that's being put out by the backspace key? Most others are fine, but this is the first time I've experienced a real annoying squeak from a multi-stem key like this. Is there some kind of lube that's recommended? Thanks!

Saw a post like this on reddit a while back, I could be wrong but I'm pretty sure that relubing it fixed it. Don't quote me on it, but doesn't hurt to try

Is that a Costar or a Cherry stabiliser?

If nothing is rubbing anything, lubing everything seems like a good idea as a first step

I noticed that DSA keys were actually rubbing the keyboard's sides of my KBParadise V60, my solution was to keep on using the default caps until I move on to another keyboard
