Premium distilled water for ultrasonic record cleaner

I have a kLaudio lp200 ultrsonic record cleaner

I recall a few comments on reading threads about some special high grade distilled water

i can't seem to find anything via an audiogon search
klaudio says plain distilled is what they use

woukd anyone like to chime in with recommended top grade distilled waters
what properties make these special water brands stand out and the advantage to the sound of the records

a link or two would help

on a side note Klaudio is having a sale on their silencer and I went ahead and bought one
anybody using this silencer?

thanks
