While us professional cleaners spend tons of time cleaning the tops and sides of things, often times the bottoms of cabinets, under refrigerators / ovens, the crumbs inside toasters, the water catcher under water dispensers and other “forgotten areas” are filthy with lots of crumbs, dusty greasy muck and other unidentifiable gunk of questionable origin. 🙂
Visually…. not a big deal as most people never see it, but from the angle of pest / bug / rodent prevention… these hidden areas provide a food sources for pests. Another area that rarely gets cleaned properly is floor drains, especially in breakrooms that have drink dispensing machines, vending areas and similar. If those drains get water discharged into them, they will build up drain much over time, same goes for sink drains. It’s that drain muck that drain flies consume that drives many companies crazy trying to get rid of them. The key is taking away their food source… the drain muck.
Some people go bleach happy, but that only seems to last a week and the drain flies return. Yeah, I would think the bleach would do the trick, but it rarely does. So I use a commercial grade enzyme based cleaner that literally eats the muck away. It works great, but does take time and a couple of applications depending on how dirty the drains are.
