Keeping outdoor furniture and advertising spaces clean is a major expense. Even slight reductions in this cost can produce big benefits. PURETi-treated surfaces break down organic grime caused by auto exhaust and micro-particles of soot and tire rubber. These particles mar the surface, attract dirt, and are difficult to clean. When PURETi is applied to a cleaned surface, it will stay cleaner longer, and be much easier to clean, likely with a simple rinsing.
