Shift the dirt
After you remove the carpet and grippers, a dust and dirt layer will remain on your wooden floor.
Remove it with either a soft broom or cylinder vacuum cleaner with brush nozzle;
pressure from the wheels of an upright cleaner may scratch your floor.
Use a clean, hard brush to shift reluctant dirt.
Finish cleaning with a natural detergent (cleaning soap) diluted
in water and rinse off with a small quantity of water.
No washing-up liquid – it’s not suitable for wooden floors!
For persistent dirt, leave the soap solution on the floor for five minutes
and then remove it with a clean cloth, rinsing it regularly
with clean water. After a final wash and rinse with the soap and water, give the
floor time to dry before sanding.
