HCL based toilet cleaner (Gel) stinking problem!
Greetings!
I observed that the HCL based mixed with mentholated fatty amine starts stinking after few weeks even if perfumes is added. -

Try to add little formalin in it to preserve .
Better to share formulation not exactly know what chemical reactions oxidize. -
I seriously doubt this is microbial degradation. If it’s hydrochloric acid (HCl), at pH= 1-2 then there is virtually nothing that can survive that environment, aside from extremophiles living at the bottom of the ocean in a hydrothermal vent.
I think this is chemical degradation, I am not an expert of toilet cleaner formulas, but the fatty amine might, over time, de-aminate giving you a fishy smell.
Can’t really tell much more if you don’t post the formula.
Formaldehyde will be an overkill, a) it will lose efficacy in aqueous acidic conditions by polymerization, b) will eventually react with the amine subtracting it from the mixture, c) it is a known toxic (acute) and volatile carcinogen (chronic), if you are happy to work with it, be my guest.

Lmosca & bil7 thanks for your response. Formula is quite simple 23% (33%) HCL (Hydrochloric Aicd) 3.5% and blend of Ethoxylated Fatty Alchohol and Amine (Acid Thickener) and rest is water.

Check from Nouryon (formerly Akzo), they have some good guidance formulations. Check Ethomeens especially. Imosca has mentioned the exact phenomenon going on there right now.
And formalin, run for the hills!!!!
