HDShadow Posted April 10, 2020 Report Share Posted April 10, 2020 (edited) Would like some advice. US people here and on other Xbox forums seem to recommend isopropyl alcohol for all sorts of purposes particularly cleaning the MB and other related purposes. What I would like to know is what is best as there are usually two grades available:- Rubbing Alcohol typically 70% isopropyl alcohol. This is what people on the Xbox forums usually mention. Lab grade isoproyl Alcohol typically 99.9% isopropyl alcohol. Thing is rubbing alcohol is said in some sources not always to contain isopropyl alcohol but even when it does also contains water and other substances to discourage consumption. That's very much like methylated spirits, more commonly used in the UK for the same sorts of purposes. However my research indicates that only lab grade ie. pure isopropyl alcohol is recommended for cleaning PCBs mainly because it doesn't contain water and those denaturing agents. Because it is purer it evaporates faster and is actually less good as an antiseptic because of that. Knowledgeable opinions/recommendation?

prtscn Posted April 10, 2020 Report Share Posted April 10, 2020 Just buy 99.9. 70% is ok, but leaves smudge marks. Distilled, pure Water is not dangerous, problem is that it does not evaporates quickly. Salts other electrolytes in the water makes it conductive. 1 Quote Link to comment Share on other sites More sharing options...
SS_Dave Posted April 10, 2020 Report Share Posted April 10, 2020 I use the same and I normally but 4 liters at a time just at the moment it's in short supply.

HDShadow Posted April 11, 2020 Author Report Share Posted April 11, 2020 Confirmed what I thought. There are some opportunist scammers out there particularly on Ebay who offer the 'lab grade' stuff at cheap-ish prices and then do not deliver (literally). I fell victim to one supposed UK based seller with a good six year history and the item stated as being in the UK. But it turned out both were located in China and two weeks after ordering the guy suddenly disappeared as an Ebay seller. But got my money back very quickly thanks to Ebay/Paypal - quite impressed with that. But browsing yesterday I came upon other reports of isopropyl alcohol buyers being ripped off.

SS_Dave Posted April 11, 2020 Report Share Posted April 11, 2020 The local (300km away)supplier I use is currently using it to make hand sanitiser and has said for regular customers they can still supply limited amounts lucky for me I still have a couple of liters left. I have used methylated spirits to clean PCB's in the past as-well it just takes a bit longer to dry. In all my years on eBay I have only had to get ebay/paypal involved twice once Paypal refunded my money and the other time the seller refunded my money with an apology after ebay got involved and then he asked for me to change my review.

HDShadow Posted April 16, 2020 Author Report Share Posted April 16, 2020 Interesting ^. I did not know they did isopropyl alcohol. I knew someone who use to work for them and as, ironically, they had no interest in electronics, they used their employee discount to get me some stuff I wanted relatively cheaply. Just checked their web site (UK) and their pricing for isopropyl alcohol, including VAT/delivery, for 500ml and 1L is actually very reasonable in comparison to many of the Ebay alternatives. However both are marked as unavailable in the UK at present. Not surprising in the current circumstances. Quote Link to comment Share on other sites More sharing options...
