Do I need to reapply SpectraSan 24 after cleaning the surface?
Yes, this is the safest course. We recommend reapplying SpectraSan 24 after a surface has been cleaned with a detergent solution. Not all detergent solutions affect the residual efficacy of SpectraSan , but we prefer to recommend caution. On the other hand, cleaning with plain water will not adversely affect the efficacy of SpectraSan 24.
