How to use citric acid for cleaning?

Question:I have recently become knocked up, and would like to cut down on my use of ammonia for the cleaning job I have. I know citric acid is safer and better, but I don't actually know how to use it. I did find where to buy it and all that good stuff, but I need to know mixing ratios and whatnot if it isn't too much trouble for someone out there?

Answers:
congratulations on getting knocked up, dont know ratio maybe experiment with it
