An undercarriage sprayer includes a plurality of nozzle blocks aligned side-by-side, where each of the nozzle blocks includes a lateral channel therethrough and an upward-facing nozzle cap. A conduit extends between each of the lateral channels in fluid communication with each of the nozzle caps. The nozzle blocks prevent the water supply from being crushed when driving a vehicle over the undercarriage sprayer. Additionally, the nozzle blocks may be connected such that the undercarriage sprayer can be folded or rolled on itself.
