Eventually slime biofilm will clog pumps and tubes and nozzles.

Rain-X brand has been sold and its formulation cheapened. Rain-X brand now specializes in automatic car wash bulk products.

Use a denaturant in the WW reservoir, really hot water is the cheapest. I use methanol-denatured ethanol as denaturant, wetting agent, anti-freeze and solvent with distilled water.

Scepticism is the chastity of the intellect, and it is shameful to surrender it too soon or to the first comer: there is nobility in preserving it coolly and proudly through long youth, until at last, in the ripeness of instinct and discretion, it can be safely exchanged for fidelity and happiness.

Eschew eristical argumentation. I am responsible for what I write, not for your understanding of it.
