Yes, the 15% usually does the job. I apply it with an old watering can rather than spraying it, for the reasons you state. Wellies, old clothes and rubber gloves are essential.Do you use the 14/15% stuff - or the industrial shock restricted killer swimming pool stuff Coops? I ask as I've never had the courage for the latter but a builder told me that's what would make my 27 year old stones look like new. Not sure I'd ever have the guts. The 'milder' stuff made an old rugby shirt an 'interesting' colour with a little wind spray, s I'd be scared for the grass and shrubs in the vicinity.
