Thats true Joey, but its not near as bad as Caustic Soda.
Vinegar is a cheap, mild acid and safe to use. Most homes have it to hand, so no need to rush out to local Hardware store. A lot of blockages occur at night when shops are closed.
Caustic Soda can be dangerous to use and store etc. Its a very strong acid & will certainly break down silicone in joints.
I rather my kids found an old bottle of Vinegar in the shed, rather than an old bottle of Caustic Soda!
When silicone is manufactured they add vinager to stop it going off. The small of sanitary seal is actually a vinager smell and a fungacide smell reacting. When you introduce air they both go off. Sanitary seal will not go off if its wet thats why Tec7 is now used so much. If you use vinager in say a shower tray/under a bath where you cannot get to the joints you will cause serious damage.
If you look up the PH of vinager you will actually realise that its not mildly acidic.
Just for fyi I was not always involved in plumbing. I imported silicones for years(Dow Corning Geocel brand)
I dont care what anyone uses but believe me as we know caustic soda to be lethal we will be careful how we use it. We assume vinager to be mild. Just pour malt vinager onto a wooden toilet seat and you will see the damage...
But again really i always tell everyone my advice is friendly and not ment to offend.
