How can I win freestyle bitter stains bad the concrete floor?
Answers: Try power washing it...
Try to return with hold of some de-scaling chemical.. hardware shops normally get rid of it (contains hydrochloric or phosphoric acid) and water it down.
Use plenty of hose down and ventilate the room VERY powerfully.
It cleans concrete wonderfully, but does have deeply strong fumes.... be careful!
You will hold to lightly clean up the whole floor but it will come up massively bright.
Be sure to use gloves and goggles just surrounded by case.
Ask within your nearest DIY or hardware store, they will know which one is best.
