In my humble opinion Jeyes Fluid, diluted correctly according to use, is one of the most useful and versatile products on the market for gardeners - besides, what else can I put in the Mother in Law's tea,!
Skrumpy bet she won't remember you in her will and as for Pete agreeing with you he must not be either lol. joke aside... I use Jeyes for many things apart for sterilising soil, I clean my greenhouses,glass and floor, patio ...no not got a mother - in law thank god ...nor am I one lol
