Upon arrival tenant had notified me of the kitchen clog. I ran my snake through the clean out behind the kitchen wall in the laundry room. But unsuccessful due to the drain having large amount of gunk in it line. I had to remove the P trap assembly and run my flex shaft through the kitchen drain. Eventually I was able to clean up the gunk from the drain. I put the Ptrap assembly back together and ran the hot water side for about 5 minutes to clear out whatever gunk was left inside. The water did not back up. I let the tenant know that after she done in the kitchen to at least run hot water for a couple of minutes once a week.
