Since reading about the Visible Dust (brush) cleaning method a while back, and later on some guy trying it out for himself using self-sourced brush etc., I've been looking out for a suitable brush locally when I'm out.
Yesterday I found what I was after in a local artist/craft shop, a £3.99 0.5" wide artists brush with acrylic handle & fine nylon bristles (brush is a Daler-Rowney System 3 SY21 Long Flat if you want to find one for yourselves).
I cleaned the brush twice with Isopropanol (also known as IPA - get it from your local chemist @ £5-6 per half litre), then used a can of compressed air (99.99% pure) to dry it thouroughly while at the same time it should be applying a static charge to the bristles.
I took a shot of the sky @ f22 and it showed about 8 medium'ish dust specs, cleaned the sensor using 2 wipes from left to right then right to left, and after each wipe I used the compressed air to blow of any loose dust that might be there. I then took another shot of the sky and NO DUST AT ALL, zero, zip, nada, none
After the cleaning which took less than 2 minutes, I blew off the brush again and covered it so as to prevent any contamination until the next time.
So for less than £10 I have an effective sensor sleaning solution. I also use the IPA for cleaing PC components, so it wasn't really an extra expense for me.
I just thought I'd pass the info on if anyone might be interested, because I think this method done at more regular intervals when necessary, might be better than using the pecpad method as nothing is pressing too firmly against the sensor, nor is any liquid.
Cheers
