==New technologies== ===Ultrasonic cleaning===
In some cases, such as hospitals or large hotels, clothes dryers may be considered necessary, either for regular use or (preferably) only as a backup. It is perhaps inevitable that laundromats will have dryers as well, if only for urgent situations where a customer needs or wants to dry clothes quickly. In this case, more efficient dryers such as {{WP p|Clothes dryer#Heat pump dryers|heat pump dryers}} and {{WP p|Clothes dryer#Mechanical steam compression dryers|mechanical steam compression dryers}} should be considered. Gas dryers may also be more efficient and have lower carbon emissions.{{sp}} Where energy ratings are given, these should be considered. More efficient dryers are likely to be more expensive up front, but will have lower ongoing energy costs, which will be very significant in cases of frequent use.

===Ultrasonic cleaning===
Ultrasonic cleaning is currently being investigated as a possible alternative to conventional [[dry cleaning]].
Ultrasonic waves pass through a solution of water and soaps, and the molecules (should this say "particles"?) of soil, being more dense than the fiber, separate from the fabric.
Results have been encouraging enough that it is being developed further, but the effect on fabrics is not completely clear yet. <ref>[ Training Curriculum for Alternative Clothes Cleaning], the Massachusetts Toxics Use Reduction Institute, University of Massachusetts.
