I'm trying to find a business grant on grants.gov to start a pressure washing company. The small business administration is closed because of the Coronavirus. I'm not sure which Grant is the one that I need and I'm not sure how to fill out the form because of all the fancy words. Anybody reading this start a business with a grant?
See a small "Community" bank in your area. Or a credit union. Also, check with SBA. They are open. Not sure why you think they are closed. You can not walk in but you can apply online. And, call them. https://www.sba.gov/funding-programs/grants/grants-programs-eligibility
No one is going to gift you money to start a pressure washing business.
I'm presuming you already have a pressure washer, so go get a business license, some insurance and post your services on your neighborhood blog like NextDoor.
