So my shirt got stained. I put away the ring and devoted to wash my shirt.

Hi,
Does the bolded part make sense to you? Is it clearer to reword it as "concentrated myself on washing my shirt?" Thanks.

No so is necessary at the beginning of the first sentence.
"I concentrated on washing my shirt" sounds natural.

Angliholic forgot to bold "devoted to wash my shirt." Does it make sense to you?
I think Philip already addressed this for you.

By the way, doesn't "I concentrated myself on washing my shirt" sound good to you?

No, that doesn't work at all.

As I said in the other thread, if the shirt is stained, there's no point in washing it. Throw it out.

I don't know what your mother tongue is, but in English "concentrate" is not a reflexive verb.
