I have this building that has brown upvc gutters and downpipes. It looks like the sun has made them fade to almost white.
If you scratch it lightly you can see the original colour.
Any recommendations on what to use to bring the colour back?

[Mike Halliday]

I've seen this and would think you would have to use an abrasive to remove the top layer of the UPVC  it's not something that will clean off. I would not be keen on doing such a job as it will be very time consuming and laborious

It needs replacing , to try and restore it will cost a similar amount and the results don't generally last long and it goes dull again , then you have an unhappy customer saying I paid you all this money and look it's as bad again ---------

You would be wasting your time even trying. Just advise the customer if they want it to look like new just get it replaced.

I've got brown gutters on my house which is 20 years old. They had faded almost to white, but a mate who is an organic chemist, and he suggested I spray WD40 onto a rag, and wipe it on to the gutters and downpipes. I tried this last year and it works. Promise. You do need two coats, but they look shiny and new.

And how long did it take you ?

It worked because it has acted like a penetrating sealer and soaked into the pvc.  Most things like this would work provided the molecules are small enough to penetrate.  But it is a time consuming job but still cheaper than replacement provided the guttering is otherwise in good condition.  Furniture stain, teak oil, linseed oil, boot polish & many others would probably all work as well as long as the plastic is clean, dry and free of dust.  We have another product call Liquid Poultice A & B which would probably also work.  We once made faded green, sun blasted uv damaged aluminium window frames look like new.

It probably took a while but anything that improves aesthetic appearance and makes a happy customer is potentially a great earner

[Smudger]

Quicker and cheaper to replace - that's my point, but until I get a time frame it's a bit of guess work

Guttering, joints, down pipe for a typical house would be around £80 for the bits and then 3 hours to put up

I will take your word for it mate as I have no idea on replacement costs
