Having been in the plastic fabrication business prior to retiring I learned about Novus products.
If I have a new acrylic windscreen wether it be on a motorcycle or cart,
I always clean them with Novus #1 and a soft microfibre cloth.
If the windscreen is really dirty I’d clean with mild detergent water and soft cloth before using Novus.
I’ve never had to use #2 or #3 though,
I think that is because I use the #1 often,
and before the windscreens get really bad.
