Quoted from RoyF:Sample ordered, thank you!
What mixture ratio would that be, Ultra Dust to water? Use distilled water or regular water (I have ready access to distilled free water)?
My Pleasure......I hope this is of help.
As everyones Water Supply is different, distilled is preferred, but not not needed.
I have had a few pms on ratio.
Always start a new project with clean water
Clean a dirty tank frequently, especially if you can siphon any material that settles to the bottom.
Ratios? On pinball parts? I am at 1 oz to 4-5 gallons of water. Some people will go as strong as 1 ounce to 1 gallon.
I'd start weak, and check the part in 60-90 seconds, 3 minutes tops for general dirt.
Stubborn dirt can benefit from a small toothbrush, longing time, stronger solution...
Not much of that is in pinball, but restoring rusty parts, removing rouge or polish, layers of grease...
etc.
Nothing with art work!
