Lester,
As the previous posters indicated, this is a huge undertaking. Certainly not saying it can’t or shouldn’t be done, but it’s almost impossible for one individual to guide you along the way. What I would do is:
1. Work at a well run, respected car wash for at least a year. Do all you can there - beyond what they ask. If they are replacing equipment and you are not part of the team selected to do that - volunteer to help and make sure you are in on all things beyond the day to say stuff.
2. Attend regional/national conventions (when they have them again)
3. Visit other washes - other than the one you work at. Talk to other owners. Observe.
4. Begin to acquire knowledge in: plumbing, electrical, bookkeeping/business. You will get some of this working at a wash but local colleges or tech. schools will be able to supplement what you don’t have/don’t get.
There is so much to do - what I listed is just a start. There is a great deal of value in the “apprenticeship/internship” aspect of what needs to be learned and that should not be overlooked and is a great place to start.
Your initial question was kind of like going up to a surgeon and saying: “I want to be a doctor. Can you guide me through step by step what I need to do from start to finish”.
Not saying I’m a surgeon
- for sure! But the process is far more involved than it may appear and there probably is not one single person that will be able to help you alone, but rather, an accumulation of knowledge from many, many sources.
Good luck!
