Any ideas.
Just been on the net - £25 is a bit steep for something called SUPERDRY and use only once

In a sailing magazine years ago there was a plastic disc with blue pellets in it. Turned pink when wet - shove in oven and sart over - my kind of idea. £5
Can't find it anyomre though.

We used to use the blue-pink pellets in work, never seen them sold in public though. Used to dump them after a while as they seemed to only recharge a few times, and then never as good as new.

Betterware sell the white chalky stuff to go into their plastic dehumidifier thinghies. If you do not get the betterware (or alike) magazine then you are lucky, I have been trying to stop mine for years, they take no notice and never seem to call back.

Innovations and maybe maplin/RS/CPC might be worth a look as they are used heavily in the electronics industry.
 
Yes, I think you are right. It didn't recharge so well after a time.

Yes, I think I will keep away from Betterware.

Good idea re: Maplin etc - hadn't thought of them. I'm off a-hunting.
 
Woolworths sell a pvc tub into which you put some of the white stuff, which comes with it, very cheap, seems to work quite well.
We used them in our conservatory for condensation.

[/ QUOTE ] Called "self indicating silica gel" It can be used over and over again but probably people put it in an oven that is too hot. 110C should be hot enough.

Try Googling for "silica gel"
 
Yep "silica gel" found a lot

Pretty darn expensive e.g. £20 -£40 for 100 sachets etc. (well it is in my book)

Will keep looking - I only need a few. The ones that come with electrical goods - trouble is - you never know if they are saturated already do you?

Thanks to all forumites (is that right) for replies

A word of caution here, I believe the self indicating silica gel was taken off the market some years ago. If I remember correctly there was something in the colouring which was carcogenic. The uncoloured silica gel should still be available. It is expensive but if dried out overnight in a warm, not hot oven it can be reused over and over again. Don't try the microwave though.
 
<span style="color:blue">Radio Spares .. RS .. Sell packs .. Bag full of granuals .. If you put them somewhere warm you can re-use them .. Should be able to find them in online catalog .. Used in packing .. /forums/images/graemlins/smile.gif <span style="color:black">

I think the 'stuff' is calcium chloride and fairly cheaply bought from caravan outlets. Worked well for me over winter on previous boat - left abt 500g in a tub and renewed every couple of months

[/ QUOTE ] No it has not been taken off the market although alternatives to the blue/pink (containing cobalt chloride) variety are available.

This page from GeeJay Chemicals explains.

[/ QUOTE ] 100 to 120C , thats <u>cool</u> for a domestic oven. I already suggested 110C!

[/ QUOTE ] I already said that too!
