Anti-humidity crystals – home made, extenders and some useful tips.

Damp Rid and Dry Home are just a couple of brands of these crystals that suck moisture from the air. They are essential in the tropics especially in wardrobes and remove the musty smell. The containers cost quite a bit of money. The hanging ones with lemon scented deodorant in them are quick and effective but they cost a heap.

Here are a couple of things you can do to save some money in the process:

  1. Use recycled yoghurt containers with a few holes punched in them standing in jars. Vegemite jars (wide mouthed) are the best. You could cut a new base using scraps of flywire which works best of all.
  2. Recycle old pantyhose from the knee down. Fill them with fine gardening charcoal and tie at the top Hang these in closets and change them every three months.
  3. Go to your swimming pool shop and buy a massive bag of calcium chloride which are actually the white flakes that make up Damp Rid but a heap cheaper. As long as you remember it has to be kept in a sealed container or else it will suck the moisture from the air in double quick time.
  4. Kitty Litter plus calcium chloride in equal quantities works well. Buy a kitty litter with a pleasant odour and you will deodorize your wardrobes at the same time.
  5. Recycle your Damp Rid. This is a tricky process. After your container of Damp Rid has filled up with water, don’t put the contents down the toilet.
    Instead, take a heatproof bowl (glass is best) and line it with aluminum foil with NO LEAKS. Pour the moisture containing Damp Rid in and put it in the oven at a very low temperature. Evaporate your Damp Rid mix until it turns into white powder or chunks that you can smash up to make small chips. You can do this process forever. Note that the  cost of evaporation is way less than buying a new $10 jar of Damp Rid and also you can have some on standby and just use the left-over heat from the oven when you are cooking something else. Don’t overfill the bowl and also put a baking dish beneath to avoid boil overs as it is impossible to clean this out if you have a spill. Handle with enormous care!

Generally speaking, whenever you have a chance to leave your cupboard and wardrobe doors open, it is preferable to encouraging mould by enclosing them.

Don’t hoard stuff (I am getting rid of all my winter clothes and hope I won’t have a chance to wear them again!). When you go away on holidays, leave the cupboards open but if dust is an issue, throw some old sheets over the contents. Drop sheets (pure cotton) are always handy in the tropics.

  1. Can I use the damprid in the swimming pool after it has turned to liquid? It is just calcium chloride which is a chemical I use in the pool anyway?

    Ive never used this method myself but my mum says it works great.
    Use plain old blackboard chalk tied in an old sock or cheesecloth and hang in your closet. Aparently absorbs odours too. Have to change it every couple months, I think you can dry it in the sun and reuse it, but im not sure.

    My husband spilled some DampRid liquid on a lounge chair cushion. Is there any way to get it out???

  4. Damp Rid is awful stuff if you spill it! It leaves an oily residue and will continue sucking water into itself so a big mess. Best way is to pour cold water on the oily residue and blot with an old towel until the moisture is gone, if the residue remains just repeat. This does work! You can safely wash your towels as usual after blotting it up. Be careful if you vacuum up any damp rid crystals because – yep you guessed it – it will clump and suck moisture and make a mess of your vacuum cleaner.

    Due to its chemical properties I got rid of it and used plain white chalk and it works like a treat! Plus it is much cheaper and you simply put the chalk out in the sun to dry. I just tied mine in a bundle of 5 or 6 and popped it in the areas I needed it. Be aware that damp rid has been associated with health issues in some people so best check it out before using.

    • Thanks for the info Leanne. Yes, I hate it too. We gave up on it altogether and I now just air the problem cupboards a LOT but the chalk idea is interesting. I will give that a try. I certainly found that wherever I had Damp Rid, eventually I had more mould not less so I think it just keeps attracting water even in small quantities. People in Mexico buy anti-humidifiers and plug them in all over their houses but they just add heat to an already hot climate.
