I scoop twice a day in the morning I wipe the inside and outside from the top out with a allpurpase cleaner then scoop and wipe bottom just to I reach the litter inside then fill up a lil and in the night i just scoop.After wiping so and on the littermats infront of boxes I spray out with lysol, well family $ brand.U never smell anything and I have only 4 boxes for 10 cats no accidents I do it like that for 10 years
