Question About Priory Polish Cleaner

[Davey57]

I have just bought 250ml of Priory Polish Watch and clock cleaning fluid after reading good things on here about it. I have just been doing a Seiko 6119 and found it really difficult to shift the old oils etc. There was a greenish crud that was everywhere and it did not want to budge, it took me several goes with my usual degreaser and then lighter fluid to get it off. So I thought I would give some Priory a go on my next victim. I am using a small ultrasonic cleaner at the moment with various baskets and cages for the parts. I was wondering whether it would be ok to dilute the PP cleaner with hottish water, and if there would be any advantage in doing so.  It also says that the fluid can be reused, what are your thoughts on this? I can see how I might use some again to clean the dirtier parts such as the barrel and spring etc but I would be reluctant to put other smaller part into old fluid.

Hi Davey, I dilute the cleaner one part cleaner to seven parts water and put it in a jam jars with a screw top.

First give the parts a rinse in lighter fluid to take off the worst of the grease and oil.

Now place the parts to be cleaned in the jar with the diluted cleaner, and place the jar in the ultrasonic cleaner which has been filled with water at 50C. The parts are then blasted for around five minutes, or as long as it takes to clean them.

Thanks Geo, looking forward to trying it. I have been putting my cleaner directly into the ultrasonic and then dunking the bits into it, inside mesh cages etc. Do you re-use your old cleaning fluid?

[Geo]

Yes, I re-use it a few times. By using small jars it works out a very economical way of cleaning.

Have a read of my posts in this thread.

Agree with Geo on this, Priory is fantastic stuff. Just tried it out - great results without breaking the bank, do put a peg on your nose though.

Haven't had a chance to try it out yet. Despite what it said on the label about the fumes, I of course unscrewed the top and had a quick whiff -_-  Fool that I am.

Me too, bought me to my senses for a second or two.

I tried out the cleaner a couple of days ago on some parts that I thought were "clean". There was some green debris left in the gear wheels that were stopping the watch from running so I stripped them out again and gave them the Priory treatment. Fantastic results!   I feel as though I have been wasting my time with the other stuff.

Converted now.

 

By the way, I used it as advised here and put some into a small jar containing the parts and plopped it into my small ultrasonic and it is a great method and economical with the cleaner too. Would it be less effective if used in a slightly heavier walled jar or container, would the ultrasonic effect be diminished a bit?

From what I understand glass doesn't interfere with the cavitation process in an ultrasound so thickness shouldn't make a difference. The less solid the container (for example I have heard of people using solutions in plastic bags) the more the interference. It will still work, but not as well as in a glass jar or just straight in the tank. I just use different size glass jars.
