Homemade moisture trap

(29 Posts)

I have several shop bought moisture traps around my house and they seem to work.
After about a month, the crystals slowly dissolve and leaving an inch or so of water.
They are cheap to buy but I’d like to have a go of making my own.
I’ve looked o google and can only see suggestions for making little pouches.
I feel I could reuse the plastic container, after disposing of the water, then add an upper layer of sea salt….
Has anyone tried this or similar?
Thanks in advance.

My daughter put salt in a tray on the window sill and she says works well and is really damp in the morning. I can’t see that what you suggest wouldn’t also work.

I think ordinary cheap salt would work just as well.

Opening the windows for a short time also works for me.

Thank you for your replies.
Keepingquiet, my bedroom window is almost permanently open.
There is no window in bathroom.
My house is very small so 2/3 of these little trap containers generally collect moisture.
Just seemed a waste of plastic so hoped I could reuse the plastic pot and make my own.
I read cat litter may work.
I haven’t got a cat so prefer to use stuff I can use elsewhere if it doesn’t work.
Thank you 😊

I’m doing the same. I bought lots of those moisture traps last year when I had a mould problem under a dresser and in the piano. As I hate throwing things away I washed them with a view to repurposing them ( eg pot pourri). Currently having a lot of condensation on the old windows that haven’t been replaced so I put one in the kitchen window with cat litter in. I’ll try using salt in another one. I also keep any silica gel that I find included in things that I buy so I’ll use those, too, but have to be careful not to put them where the dog can get to them ( she eats anything and everything). You can buy reusable moisture traps that you put in the microwave to dry out; I might buy some of those, too.

I think baking soda (or the other soda) work just as well.

I’ve got some of that. I’ll try that, too. Might put a bit of essential oil in one, too.

Yes, air freshener as well, into the bargain. smile

Hope you get a solution soon. I was told by a damp proof expert that most moisture retention in the home is caused by poor ventilation and breathing!

We have breathe but good ventilation is key- not just windows open but doors too, especially bedroom windows at night. This improves air flow.

As your bathroom has no windows I presume it has a fan? Fans that detect moisture are better than those that just come on with the light.

Also leave your bathroom door open when in the shower if possible.

Charcoal works well, apparently.

Salt is probably the best moisture remover but is going to cost a lot more than a kitchen or bathroom fan to run, or even open a window for a few minutes, after a shower or cooking. Shut the.bathroom door to keep the moisture out of the rest of the house.

Don’t use caustic soda that will burn you badly.

Mother in Laws Tongues reduce moisture. Supposedly they were selling them in Lidl ( or Aldi, I always get them mixed up) the other week. I think even I could grow one them without killing it. I bought one for my SIL when he married my daughter and that’s still going strong.

I bought a large bag of the replacement crystals from, possibly, Lakeland but I’m not sure. Ask Dr Google.

Thanks. Worth knowing, that. I feel really guilty about buying anything single use.

MayBee70 Fri 29-Nov-24 14:52:00

I’ve got some stuff that you add to soil to retain moisture ( it hasn’t stopped raining since I bought them and that was years ago…). I wonder if they would work?

We use Kontrol Krystals to refill the moisture traps. Very effective. Easily available.

MissAdventure Fri 29-Nov-24 16:09:22

I'd imagine cat litter could be used, maybe in pretty containers dotted about.

Oldbat1 Fri 29-Nov-24 16:13:06

All air is moist anyway. Yes these traps fill with moisture but it is a never ending scenario. I always leave a window slightly open or open the double glazing vent.

We use salt in our static caravan over the winter. Just put a covering in the bottom of an old ice cream tub in each room. When we go back in the spring there’s water in the bottom of the tubs covering the salt. Throw the salt away , rinse the tubs ready for next year. It works, no damp and only costs a couple of pounds.

I put cheap salt in a dish and leave on window sill. Works perfectly well.

Redrobin51 Fri 29-Nov-24 22:19:29

I bought a bag of replacement crystals.

I think just bite the bullet & buy a dehumidifier ( the Meaco ABC ) is cheap to run, sick of drying wet windows every morning.
I don’t think those plastic ones with the beads are particularly cheap to buy & keep replacing!

I buy the large bag of refill crystals, much cheaper than the plastic container. I pierce a hole in the material across the top , pour the water out and new crystals in . The cost drops dramatically and no more plastic waste after initial buying of filled containers. I also have a tiny one on the dash of the car , works a treat .

Rainnsnow Sat 30-Nov-24 07:35:28

They are called kontrol crystal refill , large bag about £6. Lasts about 6months . Fills lots of older dehydration containers. It’s in a blue grab bag .
