Customer experience has shown that certain mat colors that are in the light blue, silver and gray shades can turn brown, yellow or green when laundered. This problem seems to vary depending upon local water conditions. Some customers have no problems in this area while others experience significant difficulties. The yellowing / discoloration is not unique to any particular manufacturer. While we have not been able to eliminate the problem, we do have a treatment that in most cases will at least partially reverse the problem.

The clean up formula shown below can be run as a separate formula assuming that all mats are clean. This formula also could be run as part of a normal wash formula with step 2 added following the first rinse after the break of a standard wash formula.
