Isopropyl Alcohol
Reddit take
AI summary of the Reddit excerpts below — not a quote
Isopropyl alcohol (IPA) is highly recommended as a versatile cleaning solvent, particularly for electronics and PC maintenance. Users value its ability to dissolve contaminants and evaporate quickly without leaving residue, making it the standard choice for cleaning circuit boards and sensitive components.
Pros
- Evaporates very quickly at room temperature
- Leaves no residue when using high-purity versions (99%)
- Effective at removing sticky residues and spills from circuit boards
- Inexpensive and widely accessible
Caveats
- Components must be allowed to dry completely before powering on
- Lower concentrations (70%) are often discouraged for electronics compared to 90% or 99% purity due to potential residue or water content
- Should be used with soft-bristle brushes or microfiber cloths to avoid damage
Best for
- Cleaning PC components like GPUs and motherboard slots
- Removing spills (e.g., soda) from electronic hardware
- Wiping down skin in sweaty areas after showering
Avoid if
- You only have access to 70% rubbing alcohol and are cleaning highly sensitive electronics where 99% purity is preferred

You can always wipe it down with 90% or higher isopropyl alcohol if it bothers you.
Grab some 90%+ Isopropyl Alcohol and a soft toothbrush. Dip the brush in the alcohol and gently scrub the slot.
Should only ever use deionized water/distilled water, Isopropyl alcohol and SOFT bristle toothbrush or a dry microfiber if you have it, if not a regular unscented paper towel with no cleaner on it.
If you can find isopropyl alcohol, giving it a brush with that will help remove whatever is left over. Look for 90%-99% if you can find it, but something like 70% will also work.
It's probably fine, just thoroughly clean with Isoprohyl alcohol, let everything dry before powering on.
You can but IPA is better as want leave anything.
Someone on here recommended wiping sweaty areas down with isopropyl alcohol after showering and it works.
Best thing is just nice cheap isopropyl alcohol and let it sit by a window for an hour to evaporate.
99.9% pure isopropyl alcohol (C_3H_8O) is the preferable thing to use ie. not, the apparently a US favourite, rubbing alcohol which may be only 70% isopropyl. Pure isopropyl alcohol is recommended because it evaporates very fast even at room temperature and because of its purity leaves no residues.
Use isopropyl lol. 99%
