Sensor cleaning advice please (1 Viewer)

Whoops misread that £8-45 for 59ml bottles, £19-95 is the price of the digipad pads, however thats still £80 for what is the same amount of fluid that costs £2-25 at the chemists!
 
Hi Nigel,

Eclipse is actually "pure" methanol.

Your point is well made, but I just thought I'd mention this before we all pop down to the local chemists..!

;)

Would it actually matter if it was pure Isopropanol or Methanol? I have ignored such stuff since school...so just wondered!

According to a health a safety sheet for it, it is Isopropanol, however Methanol is so similar chemically (they are both Monohydric alcohols and have just one atom of carbon per molecule difference), that also is available (lots more for lots less money) at the chemist.

Sorry, the chemist in me won't let me skip this.

There are two more carbons in propanol (C3) than in methanol (C1) (the one with just one extra carbon is that family favourite - ethanol). Those extra carbons do make quite a difference - especially to the volatility. Overall methanol would be better to use, but propanol would still be pretty good.

I wonder if they've changed what they put in Eclipse if, as you say, the safety sheet says it's Propanol. A colleague of mine actually ran Eclipse in an NMR spectrometer a couple of years back - it was methanol with a very small amount of an amine (probably used as a detergent).
 
There are two Eclipse fluids now - one with methanol for most sensors, and Eclipse 2 which is for sensors with an Indium Tin Oxide coating, which pure methanol can hurt, allegedly.

"E2" is made up of methanol, ethanol and isopropanol as far as I'm aware.

Keith et al....Dare I contemplate using Jessops 'Lens cleaning fluid' which claims .. 'contains isopropyl alcohol'

:h?:
 
I wouldn't, Jamie - I've no doubt that as a solvent it'll be fine, but the point of using Eclipse is that it is as near as dammit pure methanol which leaves the absolute smallest amount of residue when it flashes off (evaporates).

This is extremely important for the sensor, because you can't keep polishing away at it like you can with a lens...

I won't Keith!! Thanks

>>>If they won't ship from the US, where did you but your eclipse??<< ignore I'm just wasting bandwith!

Thanks for the chemistry lesson! ;)

As no-one has mentioned it, I use dry lens pens...if you google hard you can find the instructions for free or purchase them from various sources.
 
You might be interested to know that 'Eclipse fluid' £19-95 for 50 ml (I believe) at Warehouse express, is actually neat Isopropanol BP, which is £2-25 for 500ml at the chemists.............. quite some mark up when you consider that makes the little bottles £199-50 for 500ml

It does not smell like isopropyl alcohol, so I doubt that. I thought it was methanol?

Anyway is it the same level of purity? I bought high purity isopropyl alcohol from Maplins (spray can) and it left deposits on the sensor. So I moved to Eclipse. It is somewhat of a rip off price wise.

But for lenses Eclipse is useless and isopropyl + water is excellent.
 
If anyone is thinking of using the wet cleaning method,there are some cleaning swabs ,sold by www,cameraclean.com for just £4-95 per 10.these same swabs were sold by Intemos(now available from camera dealers,and NOT Intemos direct-do NOT order from the company itself),for £18-95 for 10.If you go to the Intemos online site(think it is still running-have not checked for a while),there is a small video which explains how to use these swabs,but if you phone cameraclean,the guy will sell you these in packs of 10 for £4-95.Not advertised seperately on the website ,but as part of a kit.He also sells the SensorSwabs as recommended for wet cleaning.But you can use the cheaper ones for both dry and wet clean.I use the dearer ones for a wet clean,then wipe over with the cheaper ones just to remove any residue.May take a couple of goes,but I have never damaged the sensor.
