We have a project with a stone/concrete/brick cleaner that is only used approximately every 15 years. It is biodegradable, low VOC, etc. However, it does not have GS or CCD certification. In fact, we cannot determine the appropriate standard for it. Stone/concrete/brick cleaners do not seem to fall under GS-37, CCD-146, or California Code of Regulations. Two questions: 1. Can any products which are used with this sort of frequency be exempt to the requirements? 2. If it must comply, under which regulations does it fall?

I wouldn't worry too much about a specialty cleaning product that's used so infrequently, especially if it isn't used during the performance period. As long as you demonstrate that compliant cleaning products were used at least 20% of the time during the performance period, you'll meet the credit requirements. However, one option that could work is to identify similar product types in the CA Code of Regulations and show that your product's VOC level is lower than the maximum allowed for the similar products. This may be enough to demonstrate to the reviewer that the product is environmentally preferred. Or you can consider the cleaner to be non-compliant and count it as such in your credit calculations (assuming it's used during the performance period). Hope this helps! Trista
