Not just a dirty sensor, but an atrociously dirty filthy sensor.

After a "mirror lock" for cleaning, I blow out the inside with the "rocket blower."

I tried the "sensor gel stick," but that seemed to make it worse.

Then I tried some regular dry swipes, it seemed ok at first, but I just noticed this today.

Any cleaning ideas? I HATE my dirty sensor.

I would take it in to be cleaned - and hope you didn't score the low pass filter using a dry wipe. A dry wipe would most certainly grind any grit into the filter and permanently damage it. If I were you, I'd stop doing the DIY thing.

May as well try a wet cleaning yourself at this point.

What are the symptoms of the dirty sensor here?

In olden times, I knew a photographer that rubbed a bit of sandpaper over the center of a lens to make it a portrait lens. Maybe a dirty sensor could serve the same purpose.

Put it in the dishwasher, top shelf and then set it on light load. That is of course if it is dishwasher safe.

This has been discussed on the forum a zillion times. Go up to the SEARCH in blue letters and put in something like 'cleaning a dirty sensor; or something along those lines; you will get all the posts on that subject, Good luck

I would not hesitate to clean a sensor with a wet solution and swabs. There are specific ones by sensor size. However I realize it's not for everyone and it sounds like the OP may have incorrectly used a dry tissue.

Or a wet piece of celery or noodle....

Either way, a pro service seems like a good idea to either fix the problem or deliver the bad news....

What do you call late, Kemosabe? It may be late for you in New Hampster!

This sounds like time for some professional help, but hopefully a competent local store if there is one...,

Sounds like Seattle isn't too far away for the OP.

Use Windex to avoid streaks.

I found a simple solution. I don't check for spots. (Only kidding)

I hate cleaning sensors, but at some point it has to be done. Like you, the first attempt will remove the offending spots and create more. I use a sensor loupe to examine it after each pass. It's a lot faster that taking a shot and examining it on the monitor.

He should have used Vaseline.

To check for sensor spots, I take a shot of the sky using a small aperture, low ISO, out of focus & slow shutter while moving the camera. Then review on the camera's LCD while zoomed into a small portion of the shot. Slew the photo left/right/up/down. Spots are easy to see and locate as they travel across the camera's LCD. Confirm spot with a magnifying glass, clean, repeat test. No computer needed.
