Just out of curiosity, has anyone tried adding a few drops of isopropyl alcohol to wetting agent as an means of helping the water off the surface.
Now one for the Barry, I think. Why does the text put a red line under the word isopropyl? As far as I can ascertain this is the correct spelling in both U.K. English and U.S. English Mike |

Mention of the ZEROSTAT Anti Static Gun reminded me of my attempts to see if anything was actually happening when I squeezed the trigger.
I took a neon indicator lamp from a scrapped electric kettle and twisted one lead so that it would connect with the the metal needle shrouded in the nozzle of the gun. When I squeezed the trigger the neon glowed. Do not touch the bare wires when squeezing as it gave me an unexpected shock. The other test that I tried was using Sellotape. I have often seen the tape attract to itself after pulling a length from the roll, static being the obvious cause. I peeled off a couple of strips about four inches long and stuck one end of each piece to the edge of a bookshelf. The tape is slightly bowed, but when the gun is aimed at the strips the taped bends and unbends. So it is definitely having an effect. I bought my gun probably about thirty years ago and it is still going strong. As to squeegees, I had one but only used it a few times, as I never really trusted the thing. I just hold the film by each end and see saw it through a pudding basin containing water and a drop of wetting agent. The way we developed film before developing tanks became the norm. Once it is hung up I take hold of opposite edges of the film using forefinger and thumb and slide down the film once to run the heavy accumulation that forms at the edges. No scratches and no water marks, but do go lightly with the wetting agent. Cheers.

Oh, and as for the underlining of the words isopropyl alcohol, I found this advice in the English-Ukrainian Dictionary, of all places: Translation memories are created by human, but computer aligned, which might cause mistakes. They come from many sources and are not checked. Be warned. Terry S |

That's one way to do it, but in the very dim and distant past a local press photographer, needing to print for the evening paper, and with a very short deadline, rinsed the film, then soaked it in methylated sprits, the light the sprit with a match, film dried and was printed in 5 minutes, he made the deadline, I was there when it happened so I know it worked, but I have never found a need to try it myself

I read about using alcohol on glass plates in a detective story that was written in Edwardian times.
The detective needed the prints urgently. So the trick has been around for quite some time. Cheers.

Thanks all, and here was me thinking that a few drops might be used rather than a bucket full.
The meths trick must have been spectacular. I must admit that I consider my meths too precious for anything else other than using in it in cocktails The purple coloured meths are ideal for "blue lagoons" Mike |

Quick Drying
Some time ago (pre 2000) Tetenal used to market something called Drysonal. It was also claimed to have properties to be anti-static. I cannot remember it having any particular smell, but when I spilled a few drops it certainly evaporated quickly enough. I used one bottle of it but never used it again. It certainly worked with a 35mm film and reduced the drying to about 20 mins.
My darkroom at the time was in the loft. with it being blistering hot in summer an icicles on the end of your nose in winter. I had been plagued with dust at the time and yes the anti static did improve it a lot. If you want to try Isopropyl alcohol the easiest place I have found to buy it is the country wide company of RS Components. I bought 2 litres last week because I make my own antivirus spray for surfaces and hands (70% alcohol 30% distilled water and even at £18 a litre still cheaper than a bought concoction). UPDATE I have just googled Drysonal and it seems it may no longer be in production. There are references to it by mostly dated in the early 2000's and nothing on the Tetenal website that I can find Last edited by John King; 10th January 2022 at 08:14 AM. |

You need a 1-ml measure. I had 1ml plastic pipettes available. Lacking an official pipette-filler, I attached mine to a 1ml syringe using a 1cm piece of surgical tubing, because you really don't want to get this stuff in your mouth (believe me, I have). You could probably use a longer piece of tubing on the syringe to make a kind of plastic anteater and thus dispense with the pipette. |

As for measuring it, I use a small 5ml syringe, which I got from my local chemist. Terry S |
