Scratches on MacBook Air

I got a MacBook Air 15 inch space grey and today was the first time in 3 Months were I actually cleaned it.

I used the whoosh cleaning spray and the cloth that comes with it.

So Im diagnosed with OCD so please don't judge 😅. I found a tiny spot and I try to clean it off multiple times, as it was finally gone I was left with this stripes.

What does that look like to you is residues from the cleaner or did a damage the aluminum , cause it is not visible on the other (where I didn't clean).
