My neighbour had some old decking and garden furniture she wanted cleaning, so I agreed to do it for free on the understanding I have never done decking so cant guarantee how well it will turn out.
I really wanted to try the flat surface cleaner on it but wasn't sure if there was a certain nozzle that you needed ? I have 15035 in mine at the moment would they have been ok or not ?
I defiantly learned a few lessons doing it first of all check for rot, lucky for me she already knew about it, plus i forgot about the 3 coats of decking paint she had on ( I thought it was just mould) and just went straight at it, could of got me in trouble if it didn't all come off.
And after i cleaned it i asked her if i could try some hypo, she said go for it I literally had it on for 2 mins and it was bleaching some spots more than others, started to panic and washed it straight off then reapplied to even it out. But I didn't dare leave it on for 20 mins its potent stuff
Well a few lessons learned.
