Auto sleeper symbol 2006 black side panels

Hello i have a autosleeper symbol 2006 and the black side panels are looking very tired .
any advice on cleaning products to bring them back to Life would be very welcome ,it has been suggested thay i try a product called carplan original black trim and bumper shine ? any thoughts .
Thank you

First stop try this, well known on here and works a dream, just do a wee hidden bit first..

Get a bottle of boiled linseed oil, and one of white spirit

Mix 50/50 and apply with a wee sponge, wipe of with a  microfibre cloth.

Should last about a year, then do it again......

Thanks you, will give it a go

just done my van 50/50 boiled linseed-white spirit what a difference.
