I've been asked by a lot of companies to use eco-friendly products and while I'd like to, I've tried the all and they just aren't as good as a strong acid or alkali. The H &S guys always go overboard, and with current trends for sueing who can blame them. I try not to have anything to strong in the cleaning cupboard ( even though they are locked), but for some tasks, you just can't help it.
Its easier to be H & S aware when carpet cleaning, especially with the new chemicals about, but for commercial cleaning, sometimes you don't really have a choice.
I do try to use re-cycled paper when possible, and of course it is cheaper, and bag wastage is kept to a minimum.
Probably not carpet cleaning related, but the speed I type I'm not deleting it
