The power of lemon.
We are surprised how far we can take the humble lemon. 1,2,3,4,5 uses.
Number four use was to boil the spent skin, the white skins with some rind where the pectin is. With one litre of water, the pH is 2.0 and second boil is pH 2.0 - 2.5.
The only change we will reduce the water quantity to 1/2 a litre to check the pH, hopefully it is stronger for the stubborn sulphur compounds.
Diggers CLR, straight is pH 2.5
McKenzie's citric acid (made in china) (75g $2.50 from W/H/W pH 0.9. One flat teaspoon granules, one teaspoon of hot water to mix. Cooled and pH tested.
1kg of citric acid. $25 from wesfarmers retail mob.
Free lemons in the bush and backyard. Or hunt at green grocers. Too many flowers to count at ours, so we got another lots of lemon, meyer hybrid.
We used that straight off the stove to clean the annoying t500 copper saddles and other copper additions. Then to see how it will stretch, still at pH 2.5.
At ph 2.0 - 2.5 to test the power of spent lemon citric acid, it takes burnt copper that had paint, plastics, silicone and strips it to the shiny stuff, water is black as spent engine oil. Lastly the double spent citric acid is good toilet bowl cleaner.
Currently we place it in the boiler, leave it boiling in the boiler for a few minutes so the plastic does not melt or degrade and soak it overnight.
If anyone knows if it is advisable to remove the copper coil from the t500 coil, please chime in?
Happy cleaning.
