Try Meguiars Plast-RX, about £7 from Halfords.
You can get other products, including Renovo Plastic Window Polish, but they'll probably cost more.

I used some stuff from chandlery by usual starbrite brand but some furniture polish by MrSheen would be a cheaper starting option

Some sprayhood window manufacturers specifically warn against using household aerosol waxes, as the wax coating can build up and reduce visibility.

I have been using the Renovo Polish on two sprayhoods. Pleased with the results and goes a long way for the money.
I believe it was originally manufactured for sports car rear windows.

I noticed this thread last week and wanted to comment on my experiences with Renovo window polish.
Last season my sprayhood acrylic windows were scuffed and marked due to it blowing into the boatyard when I was drying it. My sailmaker said to try Renovo polish and I bought a bottle which was not cheap. It had no effect at all so I had all the windows replaced. The other day I was reefing the genoa in a blow and the leeward sheet whipped the sprayhood several times and scarred one of the windows badly as well as a coachroof window. The marks looked like rope burns and large scores like a wire brush had been dragged across the window. I was devastated as the window had just been replaced so I tried Renovo window polish and once again it had absolutely no effect at all even with a lot of elbow grease and frequent applications of the polish.
I then took out my trusty Farecla G3 and the result was amazing, the perspex coachroof window scratches disappeared and the window looks like new. On the sprayhood window acrylic the Farecla took out almost all the scratches, you would have to look hard to see the remaining deep scores and I stopped as I didn't want to risk distorting the window. I can recommend the G3, I use it on all the GRP topsides, coachroof, cockpit and even stainless and it does a superb job. I just buy the standard classic regular liquid G3 stuff from a motor factor not the marine Profile range. I have used the Profile before but either it wasn't in stock this time or too expensive. From the Farecla website the classic G3 is a P1500 grit rating whereas the Profile range goes from P600, 800, 1200 so I would test a Profile product in case it was too coarse.
The Renovo looks and feels like a polish so to me it is no better than any other polish and it has no cutting action so doubt it could remove any stains or marks and just makes the window shiny. The final nail in the coffin of Renovo was that I followed the instructions and let it dry. It then refused to rub off at all and I had to wash it off and cut it away with Farecla!

I have found that 3M Finesse It does an excellent restorative job on spray hood windows.

I've successfully used Brasso Duraglit wadding for years on scratched sprayhood and plastic windows. It's cheap, easily available, easy to use and works really well.
For ongoing maintenance, use household wax polish, my preferred product is Pledge.
Cheap, quick, easy to use and great results.
Take no notice of the scare stories about wax build-up or other myths, I've been using Pledge for over 30 years with no ill effects on convertible classic car and boat canopy soft windows.

Trundlebug -maybe I should switch from Mr Sheen to Pledge and all will be well goinf forward. Toothpaste is the other solution which some might have on board as we dont tend to have much brasso wadding but will hunt some down.
Does anyone know how easy it is to replace these windows if all else fails ?

It's fairly straightforward to replace the windows, but not all canopy makers can weld them in, they may have to stitch them.
Not necessarily a problem but something you should know up front.
Your existing windows may have been stitched in anyway, in which case there's no difference after replacement.

As far as I know, Pledge is just a silicone oil, rather than a wax. It may help disperse water and should not build up or reduce clarity. I suspect any "polishing" effect is merely the silicone oil filling in any small scratches.
