Topic: Best way to clean??

I'm exhausted reading all this,  it might just be easier to go out and buy a new vase! :wsh:

Keep caustic soda (Sodium hydroxide) away from your glass at all costs - it destroys glass, eats away at it, turns it all nasty and cloudy.
In labs, it's always stored in plastic bottles. If it were to be put in a glass bottle, with a glass stopper the two bits would fuse together.
I don't know if the same things are used for toilet cleaning in different countries - I certainly don't think there's acid in your ordinary Domestos!
There's lots of things which remove limescale - but they're not appropriate for places which have soft water and don't deposit lime. (ie. here in Scotland.)

Personally I would not use kitchen roll for a piece with such a narrow neck.  It is prone to splitting when being withdrawn thus ending up with a chunk of paper in the vase.  I always use tightly rolled newspaper, which has more strength.

That's a good idea - especially rather than kitchen roll two bits in length - it could come apart at its little perforations.
If it's just one bit of kitchen roll deep, it's ok as long as you tear it into a thin strip at right angles to the perforations.

I just used silica gel which i purchased cheaply online. It soaks up the moisture very well & can be just skaken out as they only swell to about 2mm!

I've tried Harpic toilet cleaner and it hasn't worked at all. I found spirit of salts (hydrochloric acid) yesterday when I was in a DIY shop buying varnish so will have a go with that. Some stubborn cloudy sickness does not respond to Magic Balls, vinegar, egg shells, all those ordinary options. I also got cerium oxide to try. Now I just need the Flex-Shaft attachment for the Dremel.

hi juli  -  surprised that you are able to buy hydrochloric acid that easily -  must surely be a weak solution??    I had it in mind to buy some Domestos this week, but if your consclusions re Harpic are negative, then I may well not bother.    I'm coming round to the conclusion that a tumbler is possibly the best idea, particularly as you can go to bed and let the thing work on its own - so may eventually go down that road.            After my comments about caustic soda, I suddenly remembered that in certain proportional mixes with water, it can generate a lot of heat  -  so probably not a good thing to put into glass  -  aside from the other potential disasters that Sue has mentioned already.    Do let me know how you get on with the spirits of salts, and I might then try, if you have some success.    I think that cerium oxide and Brasso are as good a good combination as anything, if you can actually get into the piece of glass with the flexible drive.

thanks for that  -  I will wait for the results of julie's tests  -  will be useful to see how effective it is before I rush out and invest heavily in the product.
