Does one clean Tritium sights?

I have several carry handguns having various breeds of Tritium sights. It appears to me that my oldest sights, but not so old as to be expected to be approaching their half-life, are possibly just dirty. The three dots are well-visible in the dark, but in the daytime the white dots are very hard to see. Perhaps this is a result of sloppy cleaning, getting unwanted material on the Tritium sights.
Is there any advice out there about possibly cleaning the dots without harm to the Tritium? I am tempted to use some slightly soapy water, but caution suggests that I should consult with this helpful group first, before doing something I regret.
TIA,
Elmo

My understanding with Tritium sights is that the Tritium (a gas) is enclosed in the cylindrical plastic tube that is coated on the interior with a substance that reacts with Tritium to emit light. Thus cleaning the outside of the sights would not harm the sights. Clean away.
EDIT: A Wikipedia search says that inside coating is phosphor:

I would try soap and water or Windex, but I am not a expert.

The rubbing alcohol will cut oil and grease and drys quickly. You can also use the little lens cleaning cloths that are pre-treated with alcohol.

Use Qtips, cloth, tissue, etc. dampened with alcohol

Alcohol is a liquid.

The liquid can seep into the sight and loosen the adhesive that holds the tritium vials.
Ask me how I know.
I ruined a front sight that way.

And what kind of "liquid" did you use? Most cured adhesives are pretty resistant to most ordinary solvents.

From the Trijicon FAQ...
What solvents can I use to clean my sights?
Care should be taken to avoid prolonged contact of solvents on sight surfaces. Some synthetic and organic cleaning agents can affect the painted finish of Trijicon Night Sights. Immersing sights for an extended period of time in solvents may loosen some adhesive bonds. Sights can be cleaned with water by simply using a damp cloth followed by wiping with a dry cloth.
Remember, those vials are very small. I wouldn't imagine it would take a lot of liquid to qualify as "immersed".

Common rubbing alcohol. I did a job on the adhesive in a set of PT night sights.

Maybe they use an RTV adhesive which is water resistant, but not very resistant to IPA. BTW Hoppe's #9 contains xylene and amyl acetate which will dissolve many plastics and adhesives.
It sounds like that they need to a re-design if they are damaged by rubbing alcohol.

I have always wiped my sights down with Hoppes #9 while I'm cleaning the slide. I've never had a problem. According to Trijicon the tritium is in glass vials that are inside of rubber.

I don't know if the OP has Trijicon sights. He didn't specify the brand or breed.
