Dessicant(sp) where to get.

TorinoCobra71

Can someone please link my to a website that sells this? I need to put some in my safe. Some of my recently graded SAE's are starting to MilkSpot in the PCGS Holder. I wonder if this is reaction with the plastic in the PCGS slab or an improper planchet rinse at the mint. I have heard both stories from many people and not sure which is true.....

Thanks for the help all!

I've had luck at Macy's, just go through all the rear pants pockets of the jeans.

I use the 40 gram Aluminum canisters. They fit easily in my safe deposit boxes and are easy to 'recharge' in the oven.

I bought a couple of extras so when I go to the bank, I can do a quick exchange. Then I "bake" the spares and put them in zip lock bags until the next trip to the bank.

So far no problems at all in over 5 years.

I just got a 10x10 safe deposit box, what size desicant do I need to use? The 40gm or 1 lb?

I use Brent-Krueger for my silica gel needs.

I use the 40 gram aluminum canisters because they are easily recharged when they fill up with moisture. The protect 3 cubic feet.

YMMV

I have several bags of this stuff at my shop.
I suppose I ought to sell them on the BST forum some time.
The bags are about the size of a 5 # bag of sugar.
They came out of the crates that my new machines were shipped in.
They'd be good for a full size safe or a gun safe.

The Canisters work great (bags too)... I put a digital meter in my safe deposit to test the diff with and with out... boy do they work!! without was around 40% and with came down to 29%!

Optimum humidity for storage is 25 to 40%. Some humidity is beneficial to some things and completely removing it is bad for business in many cases.

Don't forget that when buying desiccant you can get stuff with "Witness material" that changes colors letting you know the humidity range you're in roughly. Also you can and should get humidity indicators which change color as well.

Also you should get desiccant that can be baked so you can reuse it. However with baking one of the only ways to tell how effective or non effective it is is to weigh it which means you then need a scale.

I did corrosion control stuff for the US Navy for many years as a civilian tech rep and it's a complex subject.

well i have the ones like JapanJohn refers to... they are blue balls that turn pink when filled... mine change over in about 3 weeks... i guess my bank has a lot of humidity??? but hey better to see what's happening and control it, right?

besides... I get to see my stuff every 3 weeks

So four of those aluminum things will work I think.

I hope you mean the ones on display in the store.

Why not ask your pharmacy for some? I throw out tons of them everyday at work

AnkurJ

I am actually a pharmacist and was saving them. But most of them have already turned black or grey. And I think it would take a LOT of them to equal one of those aluminum bricks.
