Hey everyone- excuse the pedestrian questions but very new to doing my own maintenance. Did my oil, f/r diff, lube chassis, MAS clean, etc., All went well but couple post-maint questions. 1. The plastic hand pumps for the gear oil...do you clean those and keep them? Or just one use and chuck them? If the former, with what do you clean them? 2. Grease gun. Never had one before - do I leave the grease can in the gun and just ensure the cap is on the hose, or do I remove and store somehow or? 3. I got some overalls to work in, but how do you clean those ? The wife will understandably not want them in the washer 4. Best way to get oil off of the concrete garage floor? (And yes, don't get it on the floor is good advice but) Thanks and appreciate your time!
