A method of detecting microbiological fouling of felts used in paper making machines is described. A felt suspected of containing microbiological deposits is contacted with iodonitrotetrazolium and then examined for a predetermined color change confirming the presence of bacteria on the felt. The felt assumes a red color in the presence of at least one million colony forming units of bacteria per gram of dry felt within thirty minutes after the iodonitrotetrazolium has contacted the felt.
