Sluggish lamps

[Spencer Wilton]

Hi guys

 

Does anyone have an idea how to perk up some Mathmos lamps which have quite a slow flow?? I have a few that had perfectly flowing wax but cloudy or faded liquid. I replaced this with Mathmos fluid (when they were on sale!) but they seem to have slowed as I suppose the balance is quite finite!

 

Any suggestions of what could be added to perk them up a bit?

 

Mucho thanks
