We can blame it on the EEC (or what ever it's present name is)
All chemicals have to be retested and for many firms the cost is not worth
it for a lot of the chemicals used in the Armature market.
Its not all that much better for the professional.
And then its also down to this "Nanny State" where Rose clear was removed
from sale as One Fool managed to get concentrate into his/her eye and it
caused Irritation.... no lasting damage....... but ..... in something like
12 years of use it was the first incident reported..
So it's back to things like Bordeaux Mixture (Lime and Sulphur) Copper Etc
Will have to dig out my old books...
