Currently, I’m using OK 2-720 from Rotajet () this is a non-ferrous metal cleaner/brightener. Mine is a 5 litre container but you dilute the fluid with water at about 1 part fluid to 9-10 parts water - so you get a lot.
You don’t of course, need to fill the ulrasonic bath container right up!

Back to the ultrasonics again. My new 6litre tank and cheap air eraser have arrived this week.?
Please remind me. I have had conflicting advice as to whether one should blast and then ultrasonic clean or the other way round. So little help is needed there.
In addition Roy mentioned using a good watch and clock cleaning fluid but the instructions to the ultrasonic cleaning bath suggests water or water with a little washing up liquid. If the watch and clock fluid is recommended has anyone any preferences as to brand and where one obtains stuff? I do hope I do not have to purchase 6 L of fluid!?
My little Mark Clark Wren is now ready for painting. A super little kit once I had ironed out a few silly errors that I had made myself. And yes the smoke unit did fit in the smoke box, the decoder in the tank and the speaker in the boiler! Paul
