    starting a list of house hold chemicals used to homebrew developers..

    So here's my list so far

    arm and hammer washing soda heated until it stops loosing weight= anhydrous sodium carbonate

    rooto crystal drain cleaner from ace hardware (only place)= NaOH sodium hydroxide

    Acetaminophen = paracetamol for homebrew rodinal

    pic roach killer = boric acid

    20 mule = borax

    vitamin C power = ascorbic acid

    borax + Drain cleaner = sodium metaborate

    ph increaser from pool supply = could be sodium thiosulfate, potassium hydroxide (KOH) or sodium sulfite

    from these ingredients you can make

    rodinal:

    tf-2 fixer:

    get some metol and you can make d76h, mytol (xtol equivalent)

    keep the list going

    There's hyrdoquinone skin cream - but you would have to seperate the HQ from the ointment, and it's only 2% or so.

    I wonder if you can start with quinine water...

    Obvious ones:

    Coffee - cafenol developers
    Tea - toning
    Oak galls from the back yard - Pyro
    Old brown bananas and apples - Catechol
    Sulfuric acid from the car battery - dichromate bleach
    Hydrochloric acid for cleaning brickwork - shows up here and there in formulae, not often
    Potassium Permanganate - drugstore item, use for bleach for reversal processing
    Vinegar - stop bath
    Pickling Salt - Microdol-X
    Propylene glycol - feed store item, store developing agents as solution
    S. Bicarb - mix with citric or ascorbic acid for S. Citrate or S. Ascorbate
    Citric acid - canning supply aisle, mix with above
    Calgon - well, it used to be S. Hexametaphosphate, but it's something else now, Hexametaphosphate is often called Calgon.
    P. Iodide - drugstore item, fixer tester, Crawley xx developer

    I would be surprised if sodium thiosulfate or sodium sulfite were sold as pH increasers for pools. They are good at neutralizing chlorine and generally you want to control that separately.

    All the "pH plus" type products I've seen are some kind of technical-grade sodium carbonate.

    Your right thiosulfate is a chlorine reducer but I know sulfite is sold as a ph augmenter

    Sulfite is also a chlorine reducer. It reacts rapidly with chlorine and reduces it to chloride.

    Just some thoughts on these lists.

    Quinine is not related even remotely to HQ.

    Current Calgon is not recommended for use as a water softener in developers.

    If you overheat Bicarb, it can give off CO2 gas and become Sodium Hydroxide or Sodium Oxide. Very not good so watch the temp.

    Acetone, for some developers. FYI, hydroquinone is also in hair coloring -- at least, in men's hair color. Don't ask me how I know; those days are long behind me now. Better to just be natural.
