This is a shameless plug: The holiday season is closer than you
think. Is that ultrasonic cleaner really doing its job? Is the
"backup" working? Remember Lone Star Technical Services. We repair
ultrasonic cleaners, all makes and models to include some of the
"older" tube type units. Fast, Economical, Professional.
PS i have a couple of units “remanufactured” units for sale, some
with heat some without.
