It is due to the high caustic nature of most off the shelf cleaners. Most spray cleaners have a pH value over 9.5 including Caesarstone's own spray cleaner. Which means they are corrosive and caustic. This damages the stone even Granite will be damaged from the same cleaners. In quartz on lighter colours it will make the surface discolour especially around the sink area. More evident if you use a draining tray beside an undermounted sink. This will generally occur over a 4-6 year period and if you look under your stone benchtop there will be some codes and most brands including Caesarstone will have a date code e.g 12/07/08 etc. Which will give the date of manufacturer of the stone. Now the yellowing or discolouring DOES NOT happen if you use the correct pH neutral cleaners. This yellowing is reversible, and it is a simply process from a yellowing reversal kit available for DIY use and takes about 1 day to complete the treatment and can be done in stages.
