Hello, I used to have clogging problems and tried a few techniques: 1/3 white vinegar 2/3 distilled H2O (not MilliQ). I was told by my LASER Pro not to blow with too much force (he used oral pressure [blew with his mouth]). I got dizzy using this method so I used room air at light flow. I have special hoses that I cut/shortened that have the proper connector ends (male & female) for attachment to the LASER. I also used to change the distilled water on the first day of every month. This really helped.
However, once I switched to the CoolFlow and stopped using distilled water with Optishield I never had another problem with flow, temperature or clogging. I highly recommend switching. It costs a little but saves a lot of time and aggravation.
Cheers,

Coolflow IGE has been good for us — we’ve been using it in our Chameleon for about a year and a half, and it has reduced our clogging issues a lot.
To switch from Optishield, you need to completely flush, rinse, and empty the lines, and install an inline mesh filter (which is the biggest up-front cost at $150; a big jug of the premixed solution is $54, over a year’s supply). Coherent sent us a step-by-step guide.

On a related note, I heard from my friendly neighbourhood technicians that
Coherent is switching over to this stuff called CoolFlow IGE for the liquid
cooling systems. It claims to have good corrosion resistance, although I
haven't yet used it myself. I might give it a try during my next line flush
and cleanout though.
