This document may be of use to you, as it discusses safe dilution amounts (e.g. 1:100 dilution factor of 5% NaClO to water--a 1:200 ratio in your case. This document may also be of use for making sanitization solutons of NaClO.
For simplicity's sake, I'd suggest doing these calculations/dilutions assuming that your stock solution of NaClO was 10% by mass/volume (I'd suggest you also make sure that it just contains NaClO, water,and no other potentially harmful contaminants which don't evaporate at a reasonably fast rate at room temperature). Making safer-to-use dilute sterilization/sanitation solutions from concentrated NaClO doesn't require much attention to detail. Such gross approximations when diluting would suffice. So as long as you take proper safety precautions, wash your surfaces/environments thoroughly with distilled/deionized water afterwards, and that what you're cleaning doesn't contain any species and/or environmental conditions which may form harmful substances and/or reactions when combined with NaClO (e.g. peroxides, alcohols, ammonia & nitrogenous derivatives thereof, acids which drop the pH below 2, acetone, excessive heat and light, exposure, etc.), you should be fine.
I would recommend you use a dilute solution when cleaning in lieu of the stock solution itself, as using the latter would be far more dangerous to your health, be more expensive per use, would most likely be just as effective at cleaning/sterilizating/sanitizing surfaces/environments as a dilute solution, and may be more harmful/rough on your surfaces than a dilute solution would be (many many many substances/surfaces don't play well with NaClO at all.) One should strive to dilute it to the point where it would be an effective cleaning agent whilst posing as little threat to your health & surroundings as possible. It's easy to make chloroform, volatile chloramines, chlorine gas, explosions and many other day/life-ruiners with NaClO. I can't stress safety precautions enough...
As an aside, "bleach" is a very crude and ubiquitous term to describe solutions of various hypochlorite salts. I refer to my "bleach" as a concentrated 8.25% hypochlorite solution, as I don't have the time to dilly-dally with such a trivial name (yet ironically enough have enough time to smear this rant all over your thread). I hope this rip-tide of information is of use to you.
Stay safe,
