Q. Our lab just has a regular household dishwasher that we use to clean labware. I heard this is not ideal, but it’s what we have. We’re using Alcojet detergent, but the instructions say to turn it into a liquid by diluting 1:100. Can we pour the powder straight into the dishwater powder cup in the door? Anything else we should do to get the most out of our household dishwasher?
A. You can dose straight Alcojet® Low Foaming Powdered Detergent right into the cup in the door of the household dishwasher. The cup is typically sized to dose something in the vicinity of 1:100 detergent or so when diluted with the wash water. Alcojet detergent is a very robust detergent that will work well in a range of likely dilutions. When in doubt, you can always use a little more and then optimize as needed down the line.
As you mentioned, it is not ideal to use a household washer for scientific cleaning. Here are some tips that can help it do the job to slightly more exacting standards.
Taking these steps will help ensure that your lab glassware is clean and residue free, however, a laboratory grade commercial dishwasher is always the best option for critically clean lab glassware. For more about cleaning laboratory glassware effectively, please watch our new video: How to Clean Laboratory Glassware and review our Labware Washer Guide.
