I told my maid to use the detergent quantity a bit less than the suggested qty bcz I don't like the strong smell of detergent and softener, use more will cause skin cancer ga. I use concentrated ones, seems like to buy new ones every 1.5-2 months wor.
For toilet paper and facial paper, one roll and one box for each day bcz my husband and kid are 廁紙/紙巾 burners.
