A small amount of dish soap (drop or two) in a spray bottle of water will break their hydrophobic shell and they'll dry out in a day. Only drawback is if you apply too much (like a lot) it can cause the leaves to get sunburns.
Water alone and mechanical removal can take several weeks to work. It's fine on one plant but you risk spread to other plants in the house.
Just my experience growing peppers.
The dish soap rinses off easily so just wash before eating as normal.
You can't say that!!!
