How to fix scratch (from knife cut) in glass? How did this happen?

[RobertLambie]

Not that I’ve removed a scratch from glass, mate, but might be worth considering.

Cant help you there Pane…other than to pass on the knowledge that stainless steel blades dont scratch glass. So use them instead.

[David Hammond]

Are you sure you scratched the glass with the blade?

What blade and what glass? It just sounds a bit unlikely to me?

[Pane Talev]

Not sure what kind of glass. Blade OLFA 30 degrees.

Thank you Robert. I will try this.

This is the knife used.

I also was under impression that glass cannot be scratched with a knife.

I’ve done the same, with a new blade, on my brand new Custom Sport passenger side glass a few yrs back, only lightly cutting too! I no longer cut against glass with the olfa blades!

[David Stevenson]

I accidently destroyed a window in a VW Passat several years ago when tinting it with the exact same blade. Couldn’t repair it, we had to replace it. Lesson learnt. Like Simon said a stainless steel blade is the way to go if you’re cutting on glass.

[RobertLambie]

I haven’t done it before, but is it not a chipped blade or blunt blade that can score glass?

[Martyn]

correct rob, a perfectly sharp blade should not damage the glass but also dirt trapped between the blade and glass can cause damage
