Hello from Ottawa!

My partner and I have a pressure washing business cleaning kitchen exhaust systems. We are in our 3rd year of business. This is a tough business here.

Does anyone have suggestions about what chemicals work best for removing starches? We find that we always end up having to scrape in the end.

Thank you,

Cheryl

If you scrape all heavy builup first,1 cup of sodium hydroxide and 1/4 cup Dawn dish soap per gallon of water gives me excelent results.
