Anyone who has handled white dance marley at some point may have noticed that the material is tending to change color into something greyish after a while. We´ve made numerous attempts to clean that away and it normally works quite well. Here is how it´s been done.
We rent a floor polish /cleaning machine with different cleaning pouches and a vacuum cleaner for water. For spots and marks a good rough cleaning sponge works best together with VIM, Natron or spirit.
Different chemicals work for a few different purposes:
Natron / baking powder: pour out some powder and rub it in gently with some water and a sponge on e g spots from shoes or tape stains.
CIF / VIM (kitchen and bathroom cleaning, contains rubbing particles): Same as natron, but sometimes better on shoes stains. Try out.
If someone for some reason used baby powder on your floor the only way to take it off is stain remover (for bathroom, not the same as cif/vim) or products used for grease removal (degreasing) on e g cars. (Turtle has such a product) Svenska: Bilavfettning eller Kalkborttagning.
Red Spirit / alcohol : tape stains, mix in with cleaning water in machine.
Do the cleaning in this order: A scrub with the ,machine to clean off the worst dirt, use warm water and universal cleaning agent. Take off the water immediately every 2-3 meters with the vacuum. Then scrub the stains with a sponge and a suitable chemical, natron or vim/cif/kitchen surface cleaner. The go another round with the machine. Now the floor should be clean enough. Clean it manually with warm water and floor sweeper, let dry, ready!
If you want to clean a black marley beware of the polishing products, those may alter the floors color to something greyish that eventually may get black again but will take a while.
