How to get rid of dirt marks on macbook?

Question

Do it yourself

Hello everyone, ah nid help!
The situation in a nutshell. Recently arrived from Asia. The MacBook was transported in a box, and the box in a backpack, and the backpack in hand luggage.
Upon arrival, I found strange marks on the body


. At first I thought it was dirt, I didn’t bother. Then, when it came to the point, I began to clean it with a damp special cloth that came with the kit, I realized that it was not so simple. Traces are not rubbed off. I bought alcohol wipes, also rubbed for 30 minutes, to no avail. I began to doubt if it was scratches :( To the touch, it seems like a feeling that these are traces of plaque.
I decided to see what could be inside the box that stained the laptop. As a result, I found sand. In addition to the devices, there were towels and other things in the backpack , on which sand could remain after the sea.So apparently he got into the box a little.
Are these scratches on the Khan's body, or do I still have a chance? :) It's a pity, the laptop is only half a year old, under warranty. In addition to traces, there are less noticeable traces on the pictures, and they look like traces of stains.
Thank you all in advance and have a great start to the week.

Answer 1

Do not worry, external marks on the case do not affect the Russian warranty, they are not very noticeable, so there is no need to get upset.

Answer 2

Try another acetone or nail polish remover

And immediately remove all the paint from the MacBook) Rub
with alcohol, but not with alcohol wipes, but with a cotton swab with alcohol. You can "soak" the place with a cotton swab and rub it off after a while. If it's really sand.

Answer 3

Is it weak to look through a magnifying glass, is it a scratch, or is it still something that has stuck?
Well, if this is really a scratch, then trying to wipe it off with a solvent is an idea for five points.
