To help consumers make informed choices, Suffolk County Local Law 15-2016 now requires every professional garment cleaning establishment, such as dry cleaners, to post a sign informing customers about the chemical solvents used at that cleaner.

Old Lead Painted Bathroom

The Suffolk County Department of Health Services (SCDHS) created the sign based upon a review of potential health and environmental concerns of chemicals used in different garment cleaning processes. The sign was approved by the County Legislature on November 20, 2018. The chemical solvents that were reviewed are listed below.

  • Perchloroethylene (also known as Perc)
  • Hydrocarbons
  • Liquid Carbon Dioxide
  • Wet Cleaning
  • Butylal
  • Siloxane

The health and environmental factors were color coded ranging from red, which represented the least preferable option, to green the most preferable option, with yellow a category between least and most preferable.

Posting the Sign

As of March 1, 2019, all professional garment cleaning establishments in Suffolk County must post the Suffolk County Sign in two specific locations.

  • in the window of the garment cleaner, so that it can be seen by people outside the cleaner, and
  • near or behind the counter so that anyone entering the garment cleaner can easily see the sign

The garment cleaner must mark on the sign which garment cleaning chemical solvent(s) they use. Instructions on Completing and Posting the Sign

Also, if a cleaner delivers professionally cleaned clothes to homes or offices they must also state on receipts the chemical solvent that was used.

If you believe a garment cleaner is not posting the sign according to this law, or the receipts do not contain the required information, you can notify the SCDHS at 631-854-2501.
