Hi James,
As much as I agree with Diane, if you have 10 years in the making then you should'nt need to ask, but we all know that if you say "Never done office cleaning but give us a go" your chances are very slim indeed. Thats in any line of work....
So you are asking factors to take care of, I am assuming you mean a task list. Or are you refering to cleaning during the day time while office staff are their "Safety"
Well a basic list will be along the lines of this
Vacuum all areas
Mop kitchen & Toilets
Clean kitchen counters & cupboards
Damp wipe & polish desks
Dust skirting
Dust chairs
Clean glass & mirrors
Polish banister rails
Dust for cobwebs
Collect cups and place in dishwasher
Clean coasters
Dust keyboards
Dust computer monitors
Empty bins
Empty recycle bins
Now thats a basic list. Every office will be different and will want and need a different type of cleaning. Some more thorough than others.
Obviously it will depend on a number of factors, size, desity, number of staff, type of standard of clean they want. You will have to rota the cleaning as well as you wont be able to fit it all in.
Talk to the customer and find out there type of environment as this will effect the type pf clean as well.
I hope this is of some help
Dave
