Mineral spots on dome ports.

Is the anything one can add to the soak tank to minimize the formation of mineral spots. I have a glass dome with a few minor spots is the a way to get rid of the spots.

You could try either diluted white vinegar (50/50 with warm water); or, less effective, warm demineralised water.

I'm not sure I'd leave the whole dome soaking in the white vinegar solution but if you wet, say, a  cloth or towel and laid it over the glass and leave it overnight. 

You could leave the dome in demineralised water until cockroaches no longer inhabit the planet.......

Thanks for that suggestion. Has anyone had luck with Dawn dishwashing liquid?

Prevention is better than cure.  The problem usually arises when water droplets are allowed to dry on the dome.  The solution is to blow off the dome and use a large microfibre cloth to dry the dome.  When water droplets dry any salts in the water become progressively more concentrated and as the concentration increases they are capable of etching the glass.  As to a cure if they are minor marks soemthing acidic should help dissolve any deposits, otherwise people have reported success with polishing compounds.  There was a thread on here about cleaning domes for split shots which mentions a cleaning routine.

I'm not sure a dishwasher solution will do it but worth a shot if there's nothing gritty in it. 

As Chris says, prevention is better than cure but I think many of us have had the problem. I've found "Mothers Water Spot Remover" works fairly well. I've tried loads of other things (including Coke - not tried though the Taste of a Young Generation, ie Pepsi: I figure Coke is the Real Thing), screen/sunglass cleaner and none of them have worked. 

Again, as Chris explains, there is quite a long thread about this so worth doing a search. If you search on Mothers Water Spot I think you'll find it.
