Could someone please help! I have light grey wood effect laminate in my living room and no matter what cleaner I use it doesn't clean in between the grain. I am disabled so I can't scrub the floor on my hands and knees and I've had to buy one of those mops that have the microfiber pads that spin round as I can't push a normal mop. These dirty marks are driving me mad! Does anyone know of any different pads or something I could use to make it clean between the grains
