I like using solvents. I use all types of solvents. Kerosene, ligther fluid, petrol, thinners, aerosol based cleaners, etc. U name it, I’ve used it. They come in real handy to clean stains of all types; be it for household purposes or automotive ones. And so far I have no problems with any of these solvents. Until today.
Several moons back, I bought a bottle of unmarked/’no-brand’ thinner from a warehouse closedown sale. I’ve used thinners before to thin paint and to clean minor marks, so I thought all thinners are the same. During the evening, I removed several adhesive hooks from my kitchen wall tiles and it left ugly adhesive marks which were a bitch to remove. These are the spongy type which grows in strength over time. So I thought I could use a shortcut and use thinner to ‘melt’ the adhesive and I can easily remove it by scrapping it off with my fingernails.
So I poured a capful of thinner and generously drenched the adhesive marks with it. And while doing so, I drenched my left hand as well with the solvent. I have worked with thinners before and had no problems handling it without any protection. Firstly there was the usual tell tale ‘cooling’ feeling as the thinner starts evaporating off your skin. Usually that’s about it, it’s kinda ‘syiok’ if you think about it.
I poured more thinner and slowly used my fingernails to remove the adhesive gunk. Well, it worked great. The adhesive literally melted. Fast. But it seem to be doing more than just that. My skin began feeling some warmth at the areas which contacted with the thinner. I ignored it and proceeded to clean the adhesive mark. Then, it started stinging. Ok, this may be cause for concern now. Then all of a sudden, the skin around my little finger felt like it was being licked by fire. Seriously, the sensation was akin to being burnt, and you immediately knew that you’re in trouble.
I know what burnt means, coz once upon a time, when I was young and stupid, I used a hacksaw on a piece of thick PCB board, which superheated the blade from all that friction, and I accidentally placed the blade on my naked left thigh… instanto branding, taking a 3cm by 1cm layer of charred skin with it which was grafted onto the blade when I removed it.
Anyways, logic kicked in and I rushed to the water faucet and ran water over the affected skin. It took a good few minutes before I actually felt relief. Thankfully, no major harm done, other than a rather inflammed left pinkie which left me feeling a little sore. Mabbe the skin there was slightly more sensitive… I dunno.

Moral of the story? Solvents are caustic. Some mild, some more than others. And don’t buy solvents which do not have labels or brands. You never know what shit they put in it. And don’t be like me. Use protection.
