Add discussion of adjusting the conductivity of water to improve washing (starting with citations below).--Kkelly (talk) 12:16, 7 July 2015 (CDT)

The section of the Washing page on surfactants recommends Triton X-100. In July 2017, I added a link to Sustainable Solvent Use for a discussion of the health and and environmental hazards of using Triton X-100. This section also talks about a Library of Congress formula that I am not sure is still in use.--Kkelly (talk) 07:20, 27 July 2017 (CDT)

In the 2018 reformatting project, the numbered outline format was removed. Re-consider this for the treatment steps, which should perhaps be reverted to 1..2..3 numbered steps--Kkelly (talk) 14:31, 22 May 2018 (CDT)
