Spot on sensor

If it doesn't blow off I've learned the hard way to spend a little $$$ and have a pro do it. I can clean my lenses but I don't want to chance a sensor. Good luck.

Cleaning the sensor is a snap. I’ve always used a purpose made kit (fluid and swabs) and never had an issue. One time I’ve had so much junk on there I had to use 3 swabs as I recall but, all came off, no issues.

I cleaned my X-T20 and X-T3 a few weeks ago - first time using a kit with swabs and fluid. I found it quite manageable when you follow the instructions. A little anxious at first, but eventually it didn't scare me enough to not do it again some day.

Perhaps because I’ve occasionally run into dust issues while traveling, plus early DSLRs and mirrorless cameras didn’t have the capability of doing a self cleaning, I learned long ago how to clean a sensor. I think it remains a skill well worth having, and if you can get past the initial angst and take the time to learn the technique, it can be very worthwhile. Particularly if you’re traveling and find some dust on your sensor, getting it cleaned by a dealer may be difficult, or perhaps impossible, depending on where you are and what time you might have available to have that done. Fortunately, it’s far less of an issue today thanks to self cleaning features, and dust issues aren’t nearly the problem that they used to be.

You only clean the cover glass of the sensor, not the sensor itself.
You can't destroy your sensor by cleaning if you don't use huge amount of that fluid.

Has anyone used these guys before? $50 to clean a crop sensor and $75 for full frame. Price doesn't seem too bad (?) and (maybe) same day service if in NYC.

It’s been many years — and never for sensor cleaning — but I’ve done business with Photo Tech and would do so again (if I was back in NYC.)

Exactly. It’s about as simple a process as can be imagined.

I'm still a chicken 😁. Luckily the issue hasn't arisen in the recent past primarily because I rarely change lenses in the field. For gigs I bring 2 or 3 cams with what I need already mounted. For pleasure I almost do the same. Just clean the feathers from my body and I'll be ok.

That's good. As long as it is not an oil spot or something similar I have used an "Arctic Butterfly" in the past. Still have it even though I haven't used it in a few years.

Yes but long ago no, That glass cover is coated. Long ago [about 2008 IIRC] Eclipse fluid could visibly damage that coating on the Canon 5D. That problem does not exist anymore, but I'm still leery of the wet clean.
