Floor tiles appear patchy after cleaning

[markmaskery]

I've started to clean up the Victorian quarry tiles in the kitchen following the recommendations in the article on this site http://www.periodproperty.co.uk/article015.htm.

After using a dilute solution of the KF Tile restorer a lot of the tiles now have patches on them that are much lighter in colour than the rest of the tile.
Is this the original colour of the tile and is it that the darker areas need a lot more cleaning and elbow grease or has something gone tragically wrong?

This patchy appearance wasn't apparent until the tiles were completely dry.

I suffered with this problem for six months and no one could come up with a solution on this site. This is normal, don't bust a gut trying to clean them as this will continue to happen when they are dry.

For the record: cardinal red polish and HG golv floor sealer are very ineffective, expensive and time consuming - don't bother. A couple of coats of a 50/50 mix of linseed oil and white spirit is brilliant, it makes them look as good as when they are wet and is very cheap!!! I have had it on my floor now for three motnhs and the wear and tear is minimal!

I wish someone gave this advice sooner when I first had this problem.
