Bong, actually i happened to ask the guy a while back how he went about it and i still have his reply. quoting verbatim (and i have never done this myself): <quote> from a chemist I bought half a kilo of silica gel. I keep the silica gel wrapped up in a handkerchief in the airtight box along with my equipment and secure the lid. This is very very effective. About once a week (when I'm not using the equipment, i.e, when I'm not opening the box too often) I remove the silica gel and put it in an oven, set to 50 degree celsius for about half an hour. This has to be done because once the gel absorbs the moisture in the box, it doesn't work anymore. When the gel is dry, it is a beautiful, deep blue in colour. Once it has absorbed moisture beyond its capacity, it turns pink. If you heat it at a low 50-60 C in an oven or microwave, it'll turn blue again. </quote> hth, subash -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
