Hello, with 4 years of use with a canon m50. I decided to buy a Sony A6300 second hand to switch to Sony eco system as i have plans in future to get myself an A7s III.

 

As I’m waiting to get my lens which arrives on Monday. I noticed on the sensor that it have some residue left behind since previous owner cleaned it. It’s only shown in some angles but it’s there…

 

It was bought online and I have buyers protection. But I would like to solve it myself since I got it for a good price. 
 

So my question is. Is residue left from old lens cleaner easy or atleast possible to get removed by applying new sensor cleaning? I’m thinking of buying VSGO APS-C sensor cleaning kit. Has someone used it before? Is it good?

 

I’ll attach a picture of the sensor here. It looks like residue from an old cleaning.

 

best regards!

You should take a close look under a magnifying lens to make sure they are not scratches,  Once you ascertain that they are cleaning marks, use an appropriate size swabs with 2 or 3 drops of cleaning solution applied to the swab, as per instructions.  These sensor cleaning solution evapourate very quickly and if the solution has mostly evapourated while the swab is being pulled across the sensor these streaks can sometimes occur.  If this happens, restart the cleaning with a new swab but be quicker about it.

You should also invest in a good blower brush or two, one for home and one in the camera bag.  I use canned air but many advise against it.  As long as the canned air is vertical and not shaken during use, the propellant won't ever spew out - the biggest concern some people have about canned air.

I've looked and it looks like cleaning marks. I have ordered a cleaning kit so will try and see if it will be removed. Thx!
