Hi guys. I need a small bottle of iso propyl alcohol to clean delicate electronics.
I have seen a 250ml bottle on amazon for £5.50 which seems cheap enough to me but ordering off amazon for this seems a bit overkill. Can I get it cheaper off the shelves in the UK?
Also, is 99% concentration bad for cleaning electronics? If so, which percentage should I be looking for please?

Use gloves when handling.
My local independent chemist sells Rubbing Alcohol very cheap (only £2-odd for a reasonable size bottle, think it was around 400ml?) which was isopropyl alcohol. Some pharmacies call it Surgical Spirit (though one bottle, "Care" brand, I'm looking at has Methyl Salicylate & Castor Oil in it, so, best to check the label).
Apparently Boots sell their own brand Surgical Spirit in big bottles (going by this Quora post - one commenter says typical isopropyl alcohol %s can be 70% or 99.9%). (edited)
Make sure your in a well ventilated area and wear gloves and eye protection. Ideally, you don't want to breath any fumes in or get any on your skin if possible as its an irritant and is also carcinogenic, even though its in some hand cleaners, because it evaporates quickly. It's the long term exposure to skin and fumes that matters.
I guess contact cleaner is no good in spray can?
