Reddit mentions of iKlear 8 oz Spray Bottle

it's probably just dirt. get yourself some of this stuff. and a good microfibre cloth and spray it on the cloth and wipe clean it. don't ever spray anything directly on your machine, you can liquid damage it, and don't clean the computer w/ anything other than this stuff. (this is just my professional opinion, i'm sure that there are other cleaning products out there, but i will only use iKlear)

harsh chemicals in commercial cleaning products will damage the finish. you can use iKlear to clean the outside and the screen, but again, spray the cloth, not the machine.

I usually use Klear Screen or iKlear. Works great on screens and the body of the laptop, even works on pencil/pen/dirt/ect.

I have been using iKlear Apple polish for years. It's great for all my electronics (iPhones, macs, etc), though I don't use it on the display of my MacBook Pro or iMac. For the computer displays, I use a lint free cloth and water. It works great on the iPhone display, but once it's on the display of my MacBook or iMac, it seems to leave smudge marks, which must be removed with water and a cloth. I'm guessing it has to do with the coating on the computer displays, which is not present on the phone's display. I also use it to clean my glasses!

Been using this product for years and can vouch for is ability to make your Mac screen (and iPad, iPhone, and Apple Watch) look heavenly. It's also used by the tech department where I teach to maintain the hundreds of computers and tablets in use by students and faculty. 1, 8oz bottle last a long, long time.

The way we do it for all of our Retina displays is to use a Toddy cloth (read a review here), which has a microfiber side for cleaning and a silk side for polishing (this is key for a mirror finish!) and iKlear cleaner fluid, which is what I've heard AppleCare technicians use themselves.

Using the iKlear fluid on the microfiber side first, then polishing with the silk side, gives a display completely free to streak marks or swirls. Now you'll never be able to stand a dirty display!

For years, I have utilized Klear Screen Spray and a Micro Chamois Cloth. I use this combination for both screens (TV, phone, laptop, tablet) and laptop/tablet keyboards.
