Hi Guys,

does anyone know what cleaning solution to use to remove baked on dry algae i need to use something none hazardous as there are plants below,it`s on a external metal corrugated paneling,i want to spray something on it using a pump up pressure sprayer (like what Jeff 1 uses) attached to my pole,then wash it off using wfp,
cheers

Water the flowers, sheet them over, use non caustic tfr, leave to dwell for about 15 mins and wfp off then water the flowers again. I use swarfega non caustic tfr and have found it to be really good

Pure water!

Simply soak the stuff for a few minutes and it comes off easily.

If the stuff is so tenacious that you really must use chemicals, Fenwick's caravan and motorhome cleaner is really effective. It's available from Halford's, but it's a bit pricey at £8 a litre.

£8 a L you got mugged wally, homebase no name, same thing 5l less than what you pay works better
