Looking for some ideas!

We have down the centre line of our big polytunnel an Apricot a couple
of peaches and a nectarine, they have become lagged in scale (soft I think)

I cant use insecticide because we eat the fruit, I have been using a
vegetable oil based winter wash which clearly hasn't been doing the job.
We also can't use a Jeyes fluid type winter wash as the polytunnel is
our growing on place for clematis.

Intention is at some point soon to cut out the worse affected branches
and shoots and manually scrub what remains - but is there an
easier/better way to go about it?

Some webpages suggest neem oil (azadirachtin) which appears to be
approved for use in the UK for crop protection. No idea if it's ok to
use on stone fruit, though.

I gave up trying to grow citrus in the conservatory because of scale
insect.
