I’ve just returned from some shopping in Weston super Mare. Popped into the Asda, and in the car stuff section there were some Pingi dehumidifier bags (299g). Reduced on the Rollback pricing , from £8 to £5. I bought a couple.
I usually use the £1 throwaway plastic jobs, typically available from Poundland, and similar shops.
The Pingi ones are however rechargeable…, into the microwave for 6 minutes.
The contents start out as a light blue, and turn pink as they absorb moisture. As such, I assume that the contents are silica crystals.
The dehumidifiers should all be reusable - used them in labs before (just crystals) - put them somewhere warm & they should recharge to the starting state.
Please don’t use the throw away plastic ones - we should all be trying to use as little as possible of single use plastics
I agree. In fairness, though, the issue of plastics thrown away has only recently become a large public, and media, issue. The primary reason why the £1 plastic ones are sold in Poundshops, and similar, is that…
They are, yes, cheap.
They do work.
The customers at Poundshops are more likely to be people who live in poor, damp, housing. They are most unlikely, I think, to be the people who go into Sainsbury, or suchlike, and pay £15, £20, £25 for a device which still needs recharge packs to be bought further down the way.
30+ years ago, I used loose silica crystals bought in bags from a local chemicals wholesaler, and laid out in trays inside the trailer of my glider to keep winter condensation at bay. Cheap and effective, though drying the used crystals in the oven was a bit of a faf.
I don’t really want to lay trays of stuff around the MX5, so I’ll give these Pingi bags a try.
The Pingi bags are great. I’ve had one in my NC and it works a treat. Recharge it every couple of weeks generally but weekly if it’s been particularly wet.
