What strength alcohol are we talking about exactly? Vodka? Methylated spirit?
Star San
Well, that'll surely kill any nasties in there, but I'd still go with a known winner....

You shouldn't use denatured alcohol to sterilize since it is poisonous. If you're determined to use it still you need to let it evaporate completely so that the methanol or whatever other additive in the ethanol is not in your bottles. Overall, seems pretty risky to me.

is it that poisonous?, I mean I'll wait for it to evaporate but always a little bit may stay in the bottle.

As an alternative, you could soak the bottles in a bath of bleach (around 4 ml per litre) and cold water, for twenty minutes or so. This is what I used to do before I could get hold of Star San.
Generally the bleach taste shouldn't be noticeable, but to be sure it's better to rinse the bottles with hot water/boiled water before you add the beer.
This approach is easy and effective, but time consuming.

Is there no mail in your country either? Just order some star san, get it shipped to you. Probably be expensive but it'll last you for a long time and make you're life WAY easier.
I'm no expert (at all) but I did a little research on alcohol for sanitizing brewing equipment (it deserves a google search, really). Apparently the best alcohol to use for this is 70% diluted ethyl alcohol because water helps alcohol kill cells. And even then it can take about 10 minutes.
You should look into using distilled vinegar. Give that a google search and you will be pleasantly surprised, I wager!
I use about 8oz of Star San over 20-24 batches for sanitizing everything. Just mix up a gallon of solution at a time using distilled water then use a spray bottle to cover every surface that needs to be sanitized. I spray it into the bottles.
Iodophor would be a good alternative.

I'm probably not qualified to say but they do put the additives in denatured alcohol specifically so people can't drink it. Methanol is commonly used in denatured alcohol and small amounts can cause permanent blindness. In addition, 30mL is fatal in humans.
Definitely worth the price. You can reuse it over and over. Keep a spray bottle full so you don't have to constantly mix it up to sanitize equipment. A large bottle should last you at least a year, even if you brew a lot.

I don't think it's been mentioned in this thread yet, so I'll add that Star-San is specifically designed to be no-rinse. So no risk of blindness 
Can you get Iodine? The other recommended no-rinse sanitizer is Iodophor, which is just titratable iodine diluted with water to the proper ratio to be a no-rinse sanitizer that doesn't affect the flavor of the beer.
Rather than spending a large amount of money for a small bottle of it at our homebrewshop, man of us buy a large amount of it for a little money at Farmer's supply stores, it's the common sanitizer in the dairy industry, and it's used by farmers to sanitize the teats and the milking equipment on the dairy farm. And it comes in a gallon for the same price you buy a few ounces at the brew store.
You have to do some calculations based on the percetnage of iodine present to then dilute it to the recommended 12.5 ppm. For many formulations of Iodine (iodophors) that usually works out to being about 1 tablespoon/5 gallons of water for a no-rinse, wet contact solution that requires only a minute contact time to render whatever you want sanitized.

If you have to even ask this question......it's worth staying away from, no?
As somebody else mentioned, you can always bake your bottles in your oven to sanitize/sterilize them, too. Lots of good information out there on the temps/times to go this route.
As per John Palmer, I do 340* for 60 min with the bottles in during preheating.

Common hardware store 'denatured alcohol' is often half methanol.
See this msds sheet for what Lowes sells around here: http://www.rockler.com/tech/RTD20000136AA.pdf
You could use bacardi 181 to sanitize bottles but i'd rather not.
If the OP has a dishwasher he could use the "heat and prayer" method - make sure you're not using a rinsing agent, clean the bottles by hand and then run them through the rinse cycle and heated drying cycle twice. There's very little that is likely to survive that treatment in quantity, and a lot of people use that method. if my dishwasher worked i sure would.
It's pretty common. This is a must read if you're going to be santizing with iodine based sanitizers. Sanitizing with Iodophors
Just small amounts of methanol used to denature ethanol will make you go blind!!!! Stay away from it if you can. Use the iodine like they use in the hospitals in a diluted form. It is a non-rinse sanitizer. If you can't get that easily go for the bleach solution as suggested before or better yet, just boil them for 10 minutes.

once again, the "small amount" of methanol used to denature hardware store ethanol is often 45-50% by volume.

methanol --> alcohol dehydrogenase --> formaldehyde
And that = death
Denatured alcohol is denatured so people can't drink it so stores can sell it w/o special licensing. From what I understand it should go right next to turpentine and gasoline on your list of things to consume.

Most homebrew supply stores will not ship outside of the contiguous United States. I tried to get a kit shipped up to Alaska, and no one would ship it. I had three orders cancelled on me because they would not ship. One company even promised it, but then I got an email saying the order was canceled.
If it is not illegal to ship, you might have to have someone you know here mail you some. It will be MUCH cheaper!
That's probably because home brewing, and alcohol in general, is pretty illegal in many parts of Alaska. And it seems the authorities are pretty tough on booze even in the areas that aren't dry.
Both Northern Brewer and Midwest Supply ship outside the US. How do I know this, you ask? My wife works in international shipping at the UPS hub here in Mpls, and both NB and Midwest have packages going through there on a daily basis.

BTF Iodine based sanitizer for everything- Very fast (60 seconds) and thorough -no residual taste- even though you can do a "no rinse" I always do a quick rinse. Chlorine takes forever to rinse.
