Metal Maintenance Cleaners

Hi Ryan, cleaning products used on the building exterior need to meet the requirements of IEQc3.3 to be considered sustainable. Looking at IEQc3.3, metal cleaners are governed by the CA Code of Regulations maximum VOC levels. So you'd need to find that standard, look for your product category, and compare the max VOC level to your product's VOC level. The link to the standard in the Ref Guide doesn't work anymore, so check out www.arb.ca.gov/enf/title17_94509.pdf or https://govt.westlaw.com/calregs/Document/I93D048A045DC11E4A10180321CCBA1E2?viewType=FullText&originationContext=documenttoc&transitionType=CategoryPageItem&contextData=(sc.Default) For metal polish/cleaner, the VOC max was 30 g/L in 2005. It was updated in 2012 to separate aerosol (15 g/L) and non-aerosol products (3 g/L). The Ref Guide doesn't specify a version/year for the standard, so I believe using the 2005 version is okay since that's what would have been out when the 2009 rating system was developed.
