You can buy a grout rake to take just the top layer from the grout, then a small amount of new grout can be easily applied to create a brand new look.

Wall tile grout can be cleaned using the likes of oxalic acid. This acid should be tested in a small area prior to applying over the tiled surface using the recommended concentration and appropriate PPE. I would not recommend using this with natural stone as the surface will not be so resilient and may discolour.
Hi Yes it has to be raked out and new grout put in. Regards Tony
You could clean them with a branded tile cleaner from builders merchants , but to be honest to re-grout them is better.
It depends how bad it is, a good bleach containing abrasive cleaner like Jif and plenty of elbow grease with a quality plastic scourer is the lower end of the scale, or de/ regrouting; either way its a bit painful and labourious. Not quick fix I'm afraid.
Hi, there are special grout cleaning fluids, you can buy it in any tile shop, but it's not 100%. Best solution is to scrape the grout out with special scraper and regrout.
Hi You can buy pens that will go over the grout lines, but if your grout is discolouring it may be that the wrong grout has been used, in my opinion it is better to remove & replace with antifungal grout as this stops this happening.
The grout needs to come out sorry to say
Hi Patrick The best an cheapes solution is to use ( not chemicals provided for tiles which will cost a bit more) is thick bleach the cheapes from any market . It smells chlorine but do a job and prevent for quite long time from mould groving and yellow soap stains. Best regards Rafal
It's time consuming but worth it, buy a grouting rake only a couple of pound rake out a couple of mm of area required and re grout
You can use chemicals to clean grout, but result might not be optimal if grout is heavily discoloured and if mould is involved. In that case it will be best to regrout
You can buy grouting revivers even in pound shops, however if joints are damaged a bit you may want to regrout the area.
