cleaning of negatives/slides

Over the last 40+ years I have amassed a multitude of negatives and slides
and now wish to scan the better ones onto computer. Many of these are pretty dusty and I am wondering if anyone has any tips they could pass on.
Thanks, John.

For the negs, I'd personally use a very weak solution of soapy water, and dry them off with a film squeegee, in the same way that a film processing lab (or darkroom enthusiast) would have done. If the trannies are mounted, not too sure, but I'd guess at some sort of anti-static cleaner such as a small lens blower. Any residual dust and scratches can always be removed with your photo-editing software. I think a lot of the dedicated film/neg scanners on the market have tools to compensate for such eventualities anyway, John.

I think it's worth saying that a very weak solution means only one or two drops in a litre of water, otherwise you will end up with streaky marks. Better to get proper photographic wetting agent.

To start, given that most slides should have been in boxes and most negatives in sleeves, then a microfibre cloth used gently should be all you need.

I'd go with what steven and john are saying, just use a tiny tiny drop of washing up liquid. For those really really stubborn stains i use PEC-12 and PEC PADS. Buy the bigger Pads, they make things less fiddly.
As for me, all I know is that I know nothing.

Thanks for the tips guys; I`d heard of the washing up liquid trick but wasn`t
sure if it was just an "o.w.t". I will give it a try on some not too great neg`s and see how I get on.
Best Regards, John.

John - make sure the water is cold, not too soapy, and only keep them submersed in the water for the briefest of periods - enough to cleanse the detritus from them. Squeegee them to remove excess water, and hang them up well away from any source of heat - it stops the neg's from deforming, and there's less chance of water droplet marks on them too.

In a dust free environment too, unless you want sensor spots to look like they never existed and accept masses of dust spots instead.

So no soft furnishings and no air movement. Next time the sun streams through the blinds, check out how dust free your air is....
Best regards, John
