As promised I will be posting general efficiency comments & tips from professional housekeepers.
Do you look at your house and honestly don't know where to start?
Maria's- A general rule of thumb is top to bottom. What does that mean? Start upstairs or at one end of the house & do all tasks systematically on each level. Cleaning each room separately just adds up to more minutes of cleaning drudgery. Dust every room then remove trash from the entire level etc.
Mary - A magic eraser really is magic. Awesome in tubs & showers. Really shines up stainless faucets and cabinet pulls. (A word of caution from me - not to be used on stainless appliances).
Lisa - Gather all supplies in advance. The simpler, the better. There really isn't a need for a lot of chemicals. Lisa uses bleach, vinegar, lemon oil & stainless steel polish to make homes beautiful.
Jessica - Work in teams of two. Two people can do more together than two can do separately.
