I have successfully used these in our static van in S. Brittany when left over the winter and they do a great job. However I now have a problem that I need to resolve and perhaps a warning to others. The type that I use have a reservoir to collect the absorbed moisture, last winter a few of these reservoirs had become cracked and leaked onto the floor in a couple of places. This liquid has been absorbed into the carpet, the chipboard floor, chipboard base of the bed and skirting boards.[HI] Due to the nature of this liquid it will not dry[/HI] as it continually reabsorbs moisture. Does anyone know of a solution to this problem, I think this material is alkaline so I was thinking along the lines of some mildly acidic powder to neutralise the stuff. Any help and thoughts would be appreciated.
