The active ingredient in Wet & Forget is Alkyl Dimethyl Benzyl Ammonium Chloride. I think this is the same ingredient that is in many kitchen surface cleaners. This chemical has other names too I believe like benylkonium chloride. Benzalkonium chloride, also known as BZK, BKC, BAC, alkyldimethylbenzylammonium chloride and ADBAC , is a type of cationic surfactant which has antiseptic and anti fungal properties.

Once moss is killed from between block pavers do you have to sweep up dead debris?

Yes, I would definitely clean any debris away, if you are removing green alge, it just disapearers after a few days

Is it safe to use on patio that cat walks across

Yep my cat and dogs walk on the patio spray on a dry warm day it dries quickly and starts cleaning immediately

We have a bad infestation of lichen on a conservatory roof. Has anyone had good results at removing same?

we have had lots of moss on our patio and on the shed roof and over 6 months it has cleaned the lot but you have to do it when it is dry and then the sun and the rain clears it, it is great no scrubbing just spray it on and leave it
