One of my guys scratched a customer’s window the other day, not badly but enough to notice. (Looks like he was trying to remove bird muck)

I am pretty sure it will come out as it is not deep but not sure what works best.

Someone posted a few weeks ago about a paste or something similar but I can’t remember what it was called or find the post. Can anyone help please?

I asked him how he thinks it happened and he is adamant he never used the heel of the brush, which got me thinking, I suppose it’s possible for a birds muck to be full of grit so understandable how it could scratch.

Over the years I have had one or two customers complain of scratches and every time it was on a pane where bird muck had been removed.

Apparently works on headlight lenses:

if it is a patio door that is toughened glass and you CANNOT remove scratches from it, according to the guy who replaced the patio door I scratched.

Removing scratches involves a fair amount of effort and of course elbow grease! Do not use any abrasives such as Brasso Duraglit or any kind of abrasive papers of any kind. Window Installers and Double Glazing Repairers most commonly use very fine abrasives such as Ceria (cerium oxide) or Jeweller's rouge (iron oxide). It is important to emphasise that household abrasive cream cleaners are totally unsuitable – they just don’t work and if there is a lot of abrasive in them they will scratch the surrounding glass.

Really? G7 is a very coarse cutting compound not suitable for removing scratches. IMO

Cerium oxide applied with a rotary polisher and felt pad seems to work on VERY fine scratches but it is very slow and would take ages to remove a scratch you can feel with your fingernail.

I worked in a BMW bodyshop for 9 years as a painter and we used it on scrathched paintwork and glass and finished off with G3 then  bodyshop glaze. Only my opinion

Btw,  scratch removal from shop fronts involves the use of a da sander  with wet and dry which is far courser than any compound

Fair enough I used to use cerium oxide to remove light scratches on double glazed units which always worked for me.

cerium oxide is the most popular glass scratch remover so it must work!

Thanks for the help guys, popular opinion seems to be Cerium Oxide so have ordered some.

I will let you know how I get on.
