I have tried many products on perspex and they vary in quality. My car has hard perspex headlamp lenses which had started to cloud on the outside. I was advised to use toothpaste and it works really well. Bike screens often have an anti glare coating so not a good idea on those. I suggest trying on a tiny area to see how you get on. Soft top rear screens are a bugger but I think Frosts do something for them too.

Another problem is deciding if you have perspex or polycarbonate screen. It's not a good idea to use something like T cut on polycarbonate as the amonia in it will react with the screen and soften the surface causing more damage. A fine cutting compound used for paintwork will often improve things but sometimes the fogging can be very deep.

I used to have a mate who cleaned his crash helmet visor with those clean up tissues they give you in KFC restaurants. He kept a bunch of them in his jacket pocket. After a couple of months the visor had fogged.
