White grout gone black

[Marble Life Ltd]

If this was me I would not rake out the grout if done properly it is messy and getting all the old grout out is near impossible especially with natural stone.

If I was you I would clean and seal with something more suitable like LTP H20 then look into your maintenance of the stone. The main mistakes people make is

1.wrong product- You need a PH neutral cleaner none of this [No Swearing!]rubbish that you see on tv
2. Too much product- people have a thing about pouring half a bottle of product on the floor it is not needed just a CAP FULL
3. Never VACUUM stone you will put micro-scratches in the floor which after time build up and will get to you. instead microfibre mop with silicon spray
4. Your mop doesn't Last forever clean or change after 2 weeks or so

Your second option is to colour seal your grout this will then change your grout colour and seal at the same time acting like a epoxy grout.

That depends on the vacuum used.. you should never wet mop a floor if there is dirt on it as that pushes the dirt into the joints... best to dry mop (micro fibre) or vacuum with bristle head.

The you can clean with appropriate cleaner with a fibre mop/pad as you say.

Think your mis-understanding me you should use a micro fibre mop with silcon spray on it this should then be swept across the floor what the silcon spray does is attract the dirt onto the dry micro fibre mop and this will also attract all the dirt out the joints then a lightly damp mop and as for vacuum with bristle head you must be mad you will put scratches in the floor STONE floors all together should never have a vacuum on them, its wrong a Vacuum is for carpets!

Bristles or nylon fibres are harder than stone then?

 

[Marble Life Ltd]

In most cases no but over time the bristles will put micro scratches on the floor which build up and become more obvious

The reason for this is simple restoring stone works on the MOHS scale so the harder the stone the softer diamond you use the softer stone harder diamonds you use. (appoligies if you know this). So in theory you brush bristles are soft your stone is hard! So using a micro fibre mop with the silicon spray will just attract the dirt gliding over the stone.

Another advantage is it is IMO 3 times faster than vac anyway.

What did you use before micro fibre mops and Silicon spray..🙂...


On certain stones it is as you say not suitable to use a vacuum.. IMO these being a high polish etc.. but on honed/tumbled etc then yes it can and has been done for years by more than just me.. A normal push type vacuum is deffo a no no but cylinder types with soft brush heads can and have been used for years.. but this is only to remove heavy dirt/debri or a soft brush can be used..

We like loads of opinions within a thread and one persons way may not be anothers.. but i know a few who do vacuum or sweep floors with soft brushes and no scratches...
