Don't think so
Unless we're calling standard dishwashing detergent a 'sanitising solution,' I suppose.
Also, I didn't think much of the advice to add boiling water to glass. I personally found when bottling that boiling water greatly decreases the lifespan of the glass. If it doesn't smash immediately from the heat, it certainly gets weakened drastically. Anything that increases risk of bottle bombs is bad news, in my book.
