Grinder marks on porc

[Cranbrook]

doing a bit of retro cutting today on porc tiles to fit a led strip light in a recess, scratched all of a tile with my grinder guard, any ideas how to remove? Nightmare!

Try ceramic clean from lithofin, that normally removes metal marks from tiles.

 

[Dumbo]

Plumbers rubber, t cut, wet and dry , mix up some grout rub it with that ,

Cheers lads, tried rubbing grout but didnt work, tried jif (cif) and didnt work, was thinking of scratching it off with a grinder but thought id ask here first lol.. i'll try the suggested methods tomorrow..

The solution: Barkeeper's Friend.
Trust me!

Just had a quick read up on that bar keepers friend and im completely sold on it.. hope it comes in time for new tools tuesdays

We use Bar keepers friend on solid surface countertops (Corian) it’s really good.

For tiles I would use diamond hand polishing pads.

Start off with 3000 and if it’s still there at 50 grit you have a big problem

It's a metal scuff he has, not a scratch.
(I think!)

Ahhh, OK

Bath rubber. Toolstation sell them, made by Cramer.

I have a feeling they may be scratched 🙁

Do you have a variable speed grinder and polishing pads? Might be worth having a go on a spare tile. Depends on the Porc though.

Out of my 4 Grinders, none are variable unfortunately! Is there a bid difference to hand polishing pads?

Brasso!!

Don’t use had pads on porcelain tiles, you’ll trash them.
IF you could remove the marks by polishing them, use a cream based product, but it’s still likely to dull the surface, esp if they’re polished.

I'll take a pic tomorrow before I do anything...

Here's the scratches...

 

[Concrete guy]

Go to Halfords and look in the paint detailing section for a product called Farecla G3.

It's kind of like T cut, will need a bit of elbow grease, but it "cuts" in a very slow and controlled manner. You'll know pretty quickly if you're going to get a result. Ideally use it with a sponge applicator.

This kind of thing:-

That's the most likely solution to your problem.

For those interested, this product will remove light scratching from the surface of man made quartz (but only light marks) but you'll need a mechanical polisher with a felt mop or lambs wool bonnet to get any sensible degree of finish. sub 2000 rpm target speed preferable sub 1000 rpm.
