I thought Parker ball pens were not supposed to leak, mine has even though
it's not been stored upside down.

It's very sticky inside. Is there any good way to clean it out?
Thanks for
advice.

Isopropyl alcohol, obtainable from a store chemist but quite expensive.

About £5/litre


The last time I bought any it cost £6.99 for 500ml, well over twice
that. The label is still on the bottle. With store chemists who
actually stock it being thin on the ground, you have to take what
you can find.

While it may be cheaper in bulk, isopropyl alcohol is highly
inflammable. And so buying a litre or more for occasional use
in cleaning tape heads and the like, is not only hazardous
but probably a false economy as well. Unless that is, additional
uses can be found for it.

It is the only other alcohol, other than ethyl, that is not poisonous to
drink

Handy Hint no 387:

"Isopropyl alcohol is oxidized by the liver into acetone by alcohol dehydrogenase."

http://en.wikipedia.org/wiki/Isopropyl_alcohol

So if you're clean out of acetone but have plenty of IPA handy
you can always make your own. Just make sure you wear gloves
when handling the stuff, and don't spill any on anything plastic
- such as vinyl floor tiles and toilet seats.



12 litres last me about 3 months

Ah £5.61/l for 12 litres

Ah, but us ordinary punters can't reclaim the VAT and would only be buying
one at a time so that makes it £7.23/ per litre plus a £5.95 handling charge
which comes out at £14.18 per litre. Which in total works out at exactly 20p
more than...guess what ?
