If you’ve recently had some renovations done, then you know that lots of drywall dust can be created. And no matter how many times you clean your laminate floor, it can dry with white streaks.
To remedy this, use a 100% acetone bath wash one day and then return to your normal maintenance routine. Take care to mist the acetone on the floor and then remove it immediately and completely.
Another approach is to sweep, then vacuum (no beater brush) and use a dry Swiffer® duster to make sure all debris is gone. Buff with acetone, then mop with water and vinegar or lemon juice.
