HG parquet gloss cleaner (wash & shine) (HG product 53) is a freshly scented, concentrated mopping cleaner with shine restorer developed specially for regular cleaning of both varnished parquet floors and parquet floors treated with HG parquet gloss finish protective coating (p.e. polish) (HG product 51).
Dissolve 50 ml (half a 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 20 washes, so it's very affordable too!
