Ultrasonic washing, abrasive blasting and other techniques that remove baked-on carbon from automotive or industrial parts composed of steel alloys are not applicable typically to aluminum parts. Just one hour in an ultrasonic washer can result in deformation – namely starring and spiderwebbing – of the relatively soft aluminum surfaces, undermining aesthetic appeal as well as function.
Ask Andy: Even though I’m cleaning with an aqueous cleaner, I’ve heard that regulators can come after me for VOC emission enforcement. How can this be?
Volatile organic compounds (VOCs) are regulated at the federal and state levels because their environmental release results in photochemical reactions causing ground-level ozone, or smog, formation. Health impacts are also a concern, as VOCs have been implicated in various respiratory conditions.
One of the most critical elements, and challenges, for the food and beverage industry is creating and maintaining a clean, safe, and sanitary environment for producing consumable products. According to the U.S. Centers for Disease Control and Prevention, 48 million people in the U.S. contract a foodborne illness each year.
When attempting to answer questions about what cleaning solutions work best for certain applications and which are most cost effective, it’s important to also consider what type of parts washer would work best for the solution, the soils being removed, and the cleaning process itself.
If we asked you how long you’d like your aqueous cleaning product to last, you’d probably say something like “forever,” and you wouldn’t be joking.
In a perfect world, our cleaning solutions would last infinite lengths of time.
A few months ago we talked about the different kinds of parts washing techniques that are available, and when they should be used. Aside from basic manual washing, the four most common techniques that you’re likely to come across are agitated immersion, spray under immersion, spray washing and ultrasonic.
Today, we’ll take a deeper look into each one to explain how each is most effective and which may be the best option for you depending on your parts cleaning application:
When dealing with aqueous parts cleaning, it’s important to control the concentration of your aqueous solution in order to achieve ideal cleaning status and extend your bath life.
Although aqueous products have a lot of variables to control, they tend to offer greater flexibility which makes all of the additional attention to detail worthwhile.
