Your example sentence is OK. However, it doesn't suggest that it's the design of the keyboard that's the problem. It is entirely unclear why you can't get it clean. It could be that you're using a product that isn't working well. It could be that you're not rubbing hard enough. There are lots of possibilities. If you want to say what you said in your last sentence, say "I can't get this keyboard clean because of the way it's designed".
Ty for the input. I just noticed you're right. The intent is unclear; I should've actually rephrased my requirement as "my intent is to say that the keyboard is built in such a way that it's hard to clean or at least make it not appear like the reason for it being unclean is personal fault, as in 'I'm unable to clean this keyboard'".
Yeah, I know. I'm just used to a casual chat-grammar-style of writing on my PC.
Why can a sentence not be started with "e.g."? I've read that it's a rule but never found any reasoning for it.
"I can't get this keyboard clean" could also suggest that it's someone fault (or at least their failing).
That's fine but reserve it for chat rooms and similar. We expect to see full grammatical sentences and complete words on the forum.
To be honest, I don't know why. Sometimes we just have to accept that something is true.
