According to NMC, a global organization for mastitis control and milk quality, teat disinfectant sprayers should deliver even coverage onto the teat.
Use this idea to check the spray pattern of your sprayers each month: Hold a piece of paper above the sprayer and spray the paper. A hollow or “doughnut” pattern is unacceptable, as it results in uneven coverage. Check your equipment for clogs or damage if coverage is not uniform.
