Topic: Is this textured cylinder vase Czech?

Enzymatic laundry washing liquid is often good stuff for cleaning old glass. It gets into the nooks and crannies and gets rid of anything organic. Paint brushes and toothbrushes can be useful, and to dry a tall thing, give it a final rinse in deionised water (I just have that around because I have carniverous plants) if possible, and make a wick from a bit of kitchen roll and shove that in, down to the bottom - make the wick as thick or thin as required, and leave it to stand (upside down if possible). The paper will absorb the water as it evapourates.

Good tips, thanks. I'd never thought of using a bio detergent, and I agree deionised water is probably safer than vinegar-water for the final rinse.

Years ago, I had a tool specifically for cleaning decanters and bottles without scratching, purchased from Lakeland. It was flexible and covered with pieces of a foam-like substance. I used it to clean an Edwardian decanter, but the foam covering soon disintegrated.

If I lived in a hard water area, I'd use a little diluted vinegar before the final rinse myself, but I'm in a soft water place.
You can purchase small ball bearings covered in copper, which are soft-ish but heavy and can be used to swirl around the bottoms of difficult places. They're called "Magic Balls".
And if you time your trip to the ironmongery bit properly, you can embarrass a young man by asking him if he has ...

I once ruined the rim of a vase trying to clean and dry the bottom of it, the rim had been cut and polished, it came to a really fine point on the inside, and I took chunks out of it by wiggling a bit of kitchen roll around on the end of a knife - I levered bits off from the fine rim. 
I'm now a lot more careful and have learned a few good tips from folk here.
