Just wondering how I might go about removing a set of aftermarket stainless cones from a MK3 Neville alarm which have been siliconed on?

I have a set of original Neville stainless cones which cover the whole speaker cone and want to substitute the Johnson Ross ones that are fitted.

Is there any easy way to prise these off without scuffing the plastic cone? Just wondering if anybody has carried out this procedure as they're particularly fiddly in shape and getting any kind of grip on the existing siliconed speaker cover will be difficult.

Cheers.

I think you might struggle with that without causing damage.
There are products that dissolve silicone but normally only thin sections.
Never tried it but vinegar is meant to work but I suspect that unless you soaked it for a dogs age then I doubt it would penetrate far into the silicone.

I removed a set by warming them up with a hairdryer, get em nice and warm and twist.

The other thought I had was wd40 dissolves silicone but it's getting to it and I'm not sure if it melts plastic.

Most plastics are resistant to wd40 , certainly for the short term. Always best to use sparingly and clean it off after though.
Careful if you use heat, don't be too enthusiastic with it and keep away from the electronics as they
could be damaged at a lower temperature than the silicone. Remove the batteries!!

Edit Heat would probably soften and enable removal if it was hot melt glue rather than silicone.
They look similar.
