How to re-whiten fittings

[Jewellbags]

My moho walls are all very white but getting discolouration on the various trims and fittings outside . How do you recommend restoring them ?

I recently removed mine and gave them a light sanding and got white plastic primer and Matt laquer from Halfrauds and painted them. Only time will tell if it will be a good decision

We've used traffic film remover which seems to work well.
