I was going to suggest you do a refill
The flow will be worth it
Make sure your surf is as pure as possible with no additives
Only Glycol is a acceptable additive
To "wash" the goo from excess surf I need boil it with water or only the goo without water?
I just replace the master fluid and only leave enough for a coating on the bottle to refill it
About three months after my last post, my orange lamp, as well as the purple, started to cloud. My green lamp is hazy too, but clears up when running. I did use the Palmolive Clear detergent as surf so either I put too much or I ran my lamps too hot. Any guess?
