cleaning a recessed rear element

I have noticed a couple of specks of dust on my rear element of my da*200 which is recessed. I have tried removing the dust with a blower to no avail. only way I can think is to use a cotton swab with cleaning fluid but I am reluctant because when I have used my lens cleaning fluid on filters it always leaves streaks. It is only a couple of specks so maybe it is better to forget them rather than risk causing more damage. Any advice on the best way to clean a rear element that is recessed such as this.

You could also use a lens brush, or, if you have a good lens cloth you already use, just wrap it around a chopstick or something similar and secure it with a rubber band.

I use cotton buds (Q Tips) with a LITTLE isopropanol which should evaporate without leaving streaks - streaks generally mean there is something oily or greasy on the lens.You can also buy precision foam rubber swabs designed for cleaning delicate electronic components. If there are still streaks, try a dry cotton bud or wrap a small piece of microfibre cloth around one and wipe gently with that.

I also use a LensPen to get whatever I might not have gotten with a microfiber cloth, especially along the edges. Works wonders!
