We carry a bottle of bleach on the van, but it mainly gets used to sterilize the tank when we do a though clean of it.
There was a post of here a number of years ago by someone who uses/used it. One thing that has put me off is the application of how you get it onto the work surface at height. It is quite a dangerous chemical and you need eye protection, gloves and better to be suited up as chlorine will bleach the colour from your clothes where it drips onto.
The spray (overspray) from your application will drift with the potential to kill surrounding vegetation (customer's cherished plants
) and could also affect fish in an outside fish pond. That was enough to prevent me from taking the risk of using it neat.
Of course, bleach isn't a cleaner in itself. It makes the stains invisible to be seen, but according to those who specialise in this sort of thing, the stain is still there.
I once also heard it said that if you do bleach plastic you have to ensure that it get all the bleach off, as the sun's UV rays can react and turn it yellow. I was looking at using Cillit-Bang as I thought a cleaner with bleach was the best thing since sliced bread. I used it once on a gutter and fascia clean but I can't say I was impressed. That was about 9 years ago and we still clean that house today. The fascias and gutters haven't gone yellow as was predicted. That is burnt into my memory as I was worried about yellowing and kept a watch every time the house was cleaned for about 5 years after that.
One of our customers cleans his own window frames once a year with rubbing down compound (car body paintwork) and finishes it off with a car polish/wax and they always look good.
