silica gel or dehumidifier --- some dehumidifiers kuno have chemicals na corrosive, so watch out lang.. silica gel, 10 pesos/pack sa photoshoppe prg.

the price i mention was for the blue colored gels
these BLUE SILICA GELS if it turns into WHITE ~ its an indicator that u need to replace it with a new one.

I use these blue silica gels. Got it free from the lab of the company where I work.

These are the self indicating and reversible types.

If it turns to white or pink rapidly means it is very effective in removing moisture. No need to replace them if they turns to white or pink. This is the advantage of these blue gels. Just heat them in an oven at around 90C for an hour to let the moisture that they absorbed evaporate and it will turn to blue again. You can use them over and over.

I don't even use a hygrometer as I can tell if it's still working or not.

Jeeeez!
For those who really need a calibrated hygrometer they are available in Yana Chemodities complete with a valid calibration certificate that can be traced to an internationally-accepted standard. We are using these in our facility for ISO requirements. For the price just call them.

For those who are using the white powder as dehumidifier, just make sure that it's not Calcium Chloride or anything that has a last name "Chloride". They have these Chloride ions which can cause corrosion.
fyi: Calcium Chloride is the most common and widely used desiccant (moisture absorber) as it's cheap.

@cardinal - adto sa PRG Photoshop Naa sila baligya daghan

@boordz - Really? SHet, naa ako, pero I read man daw in other forums na okay ra as long as you don't let it touch your equipment, esp the liquid form. Layu raman ako, and it's own the plastic container. DIli japun safe?

[b00rdz]

You can't really tell that what the forums say are all true.

Just the same if you park your car near the sea, it would corrode faster than if you park it away from the sea. Sodium Chloride (salt) acting as the culprit.

is heating it under the sun acceptable?

[b00rdz]

Nope, as our environment here in the Phils is very humid. It will just absorb more moisture in the air. You need to "purge out" the absorbed water using the process of high temperature evaporation.
