Cleaning requires dislodging a soil and carrying it away from a surface. For this to happen, the cleaning or rinse fluid must energetically access the surface. However, a boundary layer of liquid with reduced flow velocities can impede cleaning. A similar effect occurs in flowing waterways, like a river or […]

You are in charge of improving the cleaning of your company’s product. You think ultrasonic cleaning is needed but need to know which frequency is best. In this two-part article, we will explore aspects of ultrasonic cleaning to make it easier to choose; in some cases, a system with more […]

A cleaning chemistry is effective due to physical and chemical properties.  In the last issue of Clean Source (1), we discussed wetting of surfaces and explained that for a fluid to wet a substrate surface, the surface energy of the substrate needs to be greater than the surface tension of […]

Summer may be almost over, but there’s still time for a splash in the pool or at the beach. Afterwards, jump into the shower to rinse off the salt, sand or pool chlorine. For the shower to do its job, however, it needs to wet your skin. This brings to […]

Blends have proven useful in improving cleaning efficacy while at the same time reducing concerns of worker exposure, environmental damage or flammability. However, in most situations, the constituents of a blend volatilize or boil at different rates; the blend changes over time. This means that cleaning performance, materials compatibility, and […]

Sometimes, a change of direction is a good thing. The phaseout of HCFC-225 is set for January 1, 2015.  Restrictions will impact manufacturing because either you or someone in your supply chain may use HCFC-225 for critical cleaning. In a move that gives manufacturers just a little relief, the EPA […]
