I know it is no longer being marketed . Something to do with changes in EU rules which means it cannot be claimed to be environmentally friendly.
I guess there could be some stock left on a chanldlery shelf.
Thanks both. I notice the data sheet for Virsol above says ' do not discharge in to rivers'. I think I thought the EVM stuff could be used / was claimed to be o.k. to use while my boat was afloat on the river and without harming wildlife. But as I type that I realise that would be unlikely...
I have been using Virosol for a couple of years on the boat and at home.
Dilute it with plenty of water - so it's economical. I re-use a EVM spray bottle, among others.
