Have you tried cleaning tough stuff with just washing soda?  It is the most 
amazing stuff.  I got it to do Hulda Clark's recommended stuff and use it for 
pans, sinks, etc. You can use it with a cloth, brush or nylon pad. I mainly use 
a brush.  And hot water.  And do a Wayne, cleaning without anything where I 
can. Any more like you at home, Wayne?  Once a week duties would do quite 
nicely; I would save all the dishes and pots willingly.  Borax of course is the 
other useful stuff in cleaning.
