Using just enough cleaner to get a job done is kind to the environment and saves you money because products last longer. You don’t have to use much of a product to have the desired effect and this has the added benefit of keeping surfaces residue free and less likely to attract dust.
Another tip to save time and energy, is to leave a cleaning product to work on a soiled surface. A small amount (left to work on its own) is more effective than using lots of product and elbow grease.
