Cleaning your compressor is very important. Otherwise, it will stop working properly or start to make noise. While cleaning your air compressor's valve, you need to remove the valve safely first. Secondly, open the valve and disassemble it. After disassembling it, use any appropriate solvent to clean it thoroughly. There are small holes too. Use some kind of small tool to clean it, and after doing, reassemble the Reed valve and attach it to the compressor.
