How can I sanitize a razor with what I might have in the household?
I don't have either of those available at home. What about rubbing alch or something?
Rubbing alcohol works. 70 percent is actually better than the ninety percent stuff. Leave it in there for 15-20 minutes.
Why do you say this? I think that 70% is totally sufficient, but I don't wee why it would be any better than 91%
Also, it shouldn't be necessary to let it sit in there for 15-20 minutes. A simple dip and air dry should be sufficient to kill practically anything.
I think anything beyond what I'm describing is overkill.... Isopropyl alcohol should kill virtually anything that's going to be on your razor.

The 70 > 90% thing only really applies to spraying it on a surface. The 90 percent just evaporates too fast.
There are three levels of Decontamination:
Sanitizing (the removal of dirt and some bacteria) should only require getting the crud off with a toothbrush and some hot soapy water.
Disinfection (the removal of nearly all harmful viruses and bacteria in the vegetative stage with little effect on spores) should use at least a 10 minute soak in: 70+ % isopropyl alcohol, or barbacide, or scrubbing bubbles, or lysol.
Sterilization (complete removal of all life forms from an object) 15 minutes in a pressure cooker with water boiling at 250 degrees is the standard for medical equipment, but even holding it over a bunsen burner until it glows red hot won't eliminate all of the Prions.
Having spent a good portion of my career involved with aseptic manufacturing of pharmaceuticals I can attest that effective sterilization can be a complex endeavor. For the purposes of sterilization of an "old" razor I would first clean the razor as completely as possible using detergents, mechanical removal of scale, dirt, corrosion etc. (ultrasonic cleaning is good if the equipment is available) and then place the disassembled parts in a pressure cooker with fresh water (distilled if available) and cook for 30 minutes at 250 F (121 C) at 15 psig and then let cool for 60 min. in the cooker. This will kill all vegetative cells and bacterial spores. If present, prions would survive (highly unlikely they would be present). Simple boiling will not guarantee destruction of heat resistant bacteria or some bacterial spores. Also, 70 percent isopropyl alcohol is very effective for vegetative cells but not spores. A soak for 15 min. is recommended to allow saturation, followed by air drying (do not rinse). Another option is dry heat sterilization. This would require the cleaning regiment followed by 360 degrees or higher for at least one hour in an oven with no moisture or liquids present (a convection oven that circulates the hot air would be preferred to insure even heat distribution). This may cause some discoloration of the metal depending on material and coating. This temperature would not be recommended for any plastic components. Again slow cooling for 60 min. is advised to complete the cycle and protect the material being cooled from thermal stress.
Understand that sterilization is a relative term and generally the wet or dry heat method will achieve 6 sigma levels or less that 1 in a million organism surviving. The alcohol method may give up to a 6 sigma result but is more dependent on penetration of the liquid to the cell wall and is not very effective with spores.
One final approach with alcohol is to treat for 3 successive days with the razor air dried after each treatment.
This is more effective for penetration and also as spores begin to vegetate they become new targets on successive days before they get an opportunity to produce new spores. Once the "old" razor is cleaned and sterilized then daily or weekly treatment with alcohol or a germicide such as Barbicide is a very reasonable approach. Keep in mind that the other tools and materials used for your shave prep including the brush, blade, dish, cream/soap are not sterile. Good overall hygiene and cleaning of the equipment and area to be shaved (face, head, body) is the best practice.
