check Ingredients on sticker, if no such sticker than DON'T BUY

Also, dunno if this issue is there elsewhere, but here in Ghatkopar, last year, at the local chemists shop, the cost of the alcohol was ~ 35 bucks. The same at my favourite electronics shop, sell for 20 bucks! Both were 70% alcohol at least on the label. Also, I asked him about the rate, and he said that was the rate.

coloured ones arent recommended as they might leave residue which might beat the purpose slightly. Also the 70% ones will take more time to evaporate as water isnt as quick at evaporation as alcohol, where 30% is water.

Concentrated ones with 99% doesnt leave any residue and offer best performance for any TIMs that we apply after that.

a typical laboratory purpose one looks like this >

Don't use coloured solutions, it will surely leave residues.

Just use a can of Deodorant or cheap perfume. It'll do the job provided you use it carefully. Use it with cotton to get that heatsink goop off.

deodorants and perfumes contains fixating agents, which are hard to dry or rub off, but are transparent. So apprently, it will affect TIM performance, as TIM works best when applied on a perfectly clean surface, so the TIm particles can fill the microscopic voids and utilize maximum surface area and transfer all those heat through it to the other surface, and even a slightest presence of any other substance can affect performance, but not much. This can be explained by the example of the performance difference of TIMs from various brands who all claims it to be of same substance, like aluminium oxide found on 80% of TIMS, but each brands has very minute difference in composition and hence the performance difference.
