Green Clean

We use enviromentally-friendly cleaning products that are both effective and safe.

Are you frustrated or unhappy, or just in need of a solid cleaning service you  can count on? We regularly hear facility managers' frustrations after they find their current poor service providers, there for many years, fail to replace the toilet paper and or hand towels, hand soap and hand sanitizer, trash is missed, windowsills are not cleaned. Floors are mopped with dirty water, making them look dirty and streaky. Dusting has fallen behind. Vacuuming is not performed thoroughly or often enough. Time for a change?
