I have an arch-nemesis who I call Mr. Sisal...
Mr. Sisal is friends with a family I clean for. Their house is generally impeccable. They are the only couple I know who can handle a one-year-old, a puppy and an all-white kitchen. I clean once a week and honestly it is pretty easy with the exception of having to deal with Mr. Sisal.
Sisal is a fibre from the agave plant that is used to make carpets, rugs, cording, etc. It is strong, durable and environmentally-friendly so it is used for a wide variety of products. I hate it.
In the middle of the all-white kitchen, Mr. Sisal sits like a lump and he is impossible to deal with. He is huge, I have only managed to drag him outside and beat him a couple times since working with these clients. The process of rolling him up and dragging him outside is exhausting and frankly it doesn't seem to make a difference. Despite my weekly broom attacks, Mr. Sisal is continually exhaling dust. I don't know where it all comes from because he doesn't get any lighter or any less dusty. Every week I roll him up and find that he has hidden a pile of dust beneath him. Why does he do this? And where does it come from every week? I don't know.
Take my advice. Buy a washable rug or a small rug that is easy to take outside and beat. Whatever you do, don't go for sisal. It is like hell in rug form.
