How to restore grey bumpers?
Discussion
So, you can use a hot air gun, it has to be very hot so watch you don't melt them, but it brings the oils back to the surface and makes it look lovely, BUT, it doesn't last once the UV gets to it, it quickly fades back to as it was before.
You can use any kind of 'back to black' bumper and tyre treatment, they are all wipe on and look good, but again, its the sort of product you need to put back on every time you wash the car.
The best long term product is Polytrol colour restorer, https://www.owatroldirect.co.uk/product/polytrol/ its available from Amazon etc. Its about the best product for longer term use, its still going to need reapplying but no where near as often as either the hot air gun or one of the other bumper trim products.

Owatrol Polytrol Colour Restorer - the small tin will do every bit of plastic on the car. Longevity TBC, but so far very impressed post a few snow foam washes. Was a recommendation from on here somewhere that I saved and then finally acted upon. Expect to ruin a few microfibres cloths too. Top tip - don't put too much on - follow the instructions carefully, and wear old clothes if there's any chance of your spilling it on yourself because it's not coming out. Also expect it to take 24 hours to fully go off, so don't put it on and then immediately need to take the car somewhere 200 miles on the motorway in the pissing rain ...The day after, you'd be fine ...

You will first need to deep clean it and by the looks of it that bumper needs a lot of cleaning!
I recommend melamine (magic) sponges and some all purpose cleaner - doesn't have to be car specific, household stuff in supermarket fine and some cloths to remove the dirty residue.
Then crack on with what you've ordered

My wifes car has a _lot_ of black (well originally blue-ish) plastic that after 23 years was looking well past it's best.
A lot of the treatments such as the C4 said stuff like "Don't apply in sunlight, don't apply if there is rain forecast and don't allow it to get wet within 24 hours, etc"
I live in the South west of the UK, it's either raining, about to rain, or the sun is blistering my skin off!
After a while I found this turtle-wax product.

Not only is it cheap, its brilliant! Can apply it in the sun, and it's dry and waterproof in abour 15 minutes.
Before:

After:

That was two years ago and it still looks great now.
Had enough to do all that, the bumpers and door handles on my car, and last week used the same bottle to do the trim on the free S60 we've been given for my daughter:

Still got loads left.
Wear gloves, and don't use it on any rubbery materials (the rubbing strips on my 740 went all sticky for a while when I did that)
