Thanks for documenting your process. Helps me understand it a bit better. Couple questions..

Recycled water from what tank?

And what exactly is Nifti? Some products, like Windex, are available on multiple continents, but I've never heard of Nifti. Wood cleaner? Bathroom cleaner? General purpose cleaner?

no worries John - It is a method I've used a few times and I'm very pleased with the results. I'm keen to see / hear of other methods.

Recycled water is from a water tank I installed a while ago - just rainwater !

Nifti - General purpose cleaner we have here in Australia - used for just about everything - plastics, playfield, posts etc..
