Get pestered all the time even after 12 years.
Advice to new starters, marketing mix and monitor what is working so that you don't continue wasting money.
Leaflets, Yellow Pages/Thomsons, newspapers depending on competition, and most importantly a refferal scheme for your customers, if they pass you a job make it worth their while, either a cash payment or future free clean.
Then keep in touch with the customers you have on a regular basis, they soon forget who you are! (fridge magnets)
Keep away from inserts in menus, school handouts, one off newspaper campaigns, fire safety booklets all this kind of crap is a total waste of money and effort.
