Cleaning Oven in a Commercial Environment

 
Here's an email from someone
asking about oven cleaning in
a commercial environment:

Ed,

We  are a cleaning  service.
Just a got a contract  with  
a school  cafe.

Want to  leave  as  little carbon  
foot  print  as  possible .  But  
need to  quick  clean .  Leaving  
the  Baking  solution on  is  not  
an opportunity .  Is  there one?

Thank you in  advance  for  for
help with this.

Good Cleaning,

I don't have any good ideas for
this person. Does anyone else?

Ed Abbott
