***BEWARE*** I have seen an increase in the number of asthma attacks in the home, which I noted that the homeowner had been tumble drying washing just before the attack happened after washing the items with the new gel type cleaners.
On the back of these cleaners are an irratant sign which is an orange square with a black X in it, its only the gel type cleaners that have it and not the liquids or powders.
I am not saying that it is the definate cause but worth considering in mind.
