HG tile cleaner (porcelain cleaner) (HG product 16) is a freshly scented, very concentrated mopping cleaner developed specially for regular cleaning of all types of tile floors and floors made of non-calciferous natural stone. This product is also ideally suitable for decorative gravel floors.
Dissolve 25 ml (a quarter cup) in half a bucket (5 l) of lukewarm water. Then clean the floor with a wrung-out mop or floor cloth, regularly rinsing it in the cleaning solution. Do not rinse or mop dry, simply leave the floor to dry on its own. 1 litre is sufficient for 40 washes, which is less than 15 pence per wash!
