Scratched windows

Brasso or Silvo are very combined with elbow grease are effective as long as the scratches are not too deep.

Used this   Link   on my previous and current caravan windows and well impressed. I had a very deep scratch on my front skylight and removed it completely with it. Only difficult bit was having to work off of a ladder  

When my current caravan went back to have the water heater repaired they asked me what I had used on the windows as they looked like new.

Brasso if they are surface or if a bit deeper then toothpaste.

If sharp then use a super fine paper 1500 to 2000 grit to soften them and then polish as above.

Not for the feint hearted, try on very small area first.

I would seriously recommend that you use nothing but a polishing product specifically formulated to use on acrylic plastic windows.

Using many other products including glass and metal polishes presents a risk of a time delayed chemical attack that can leave the window with a nasty, irrecoverable, rash of micro crazing. These appear as whole number of minute silver glints in the affected areas.

What occurs is the chemicals used in those unsuitable polishes release the inevitable stresses locked up in the plastic from when the window was heat moulded. Alcohols and acetic acid which most metal and glass cleaners contain, along with other agents cause this. 

As said this is not something that happens shortly after doing the job, it is an insidious chemical attack taking typically several weeks into months to reveal its affect.

Before saving a little of the price of buying the right stuff to safely do the job you best check what the replacement cost of these very expensive windows are before using anything else.

Many thanks for the info......Milo, I will give that bottle a try, any thing will be better than listening to my wife going on.

Ocsid...I am going to sit down later this morning and watch the videos.. Thanks

Just watched the videos, one of them used Fenwicks product.....not sure which one I will try.

Thanks again.

Its your choice obviously but I didn't find the Fenwicks as good as the Mcguires. 

Let us know how you get on 

Well, being a cheapskate, I tried Fenwicks and the result is brilliant.

My wife could not find fault, the windows are sparkiling and all marks have gone.

Big thank you for the advice....really appreciate it.
