Just open the window and get plenty of fresh air...you'll be fine. I cleaned my bathroom for 9 months with my son and he came out without any extra body parts.
The fumes of the cleaning products are less harmful than the stench fuming from your dirty house. Now put your do-rag, apron, and flipflops on and clean. Make sure dinner is in the oven for when DH comes home too! Know your roll!
You could always wear a mask when cleaning. I used to do this sometimes in our old bathroom because there was absolutely no ventillation and when I used strong cleaning products, I would taste and smell them for a while after cleaning if I didn't wear a mask...blech!
i saw on the doctors tv show recently that you can mix vinegar and water in a 1to1 ratio, and it is a great cleaning product. i have not tried it yet...but good luck
Re: Cleaning products...
You can either do your best Michael Jackson inpression with a mask, or open a window.
Will be fine.
