I’m writing to see if folks would share their preferences for
ultrasonic concentrate. I noticed I was low on that very thing, and
was wondering if their was a better/cheaper option? Who better to
ask than the Orchid community.
I’m using Stuller’s ultra-CR. It works very well at a low
concentration, (75ml to about 3.0L), but it is a bit pricey. I’ve
used quite a range of wacky mixes in the past. Years back I worked
for a fellow who swore by Wisk and ammonia. It was pretty good.
I clean an average of 30 pieces a day after repair, so I 'm a light
to moderate user. I’d sure like to hear from you folks.
Best to you all,
