I have (several) electrical connection(s) that is/are intermittent because
of dirt/corrosion/gunk etc but I can not clean properly as it is a female.
Anyone with suggestions on how to make a connection like that make a
'better' connection? Electrical spray cleaner? The proper type of 'grease'?
I would rather not cut out the connection involved with a rewire around
solution. I would rather "make my life easier through chemistry". I think
Dupont said that way back when.

Dean,
Belt and suspenders.
- Electrical contact cleaner spray
- Pinch female connector as necessary to insure a snug fit (don't over do it)
- Dielectric grease
If it's a connection that rarely if ever needs to be separated, and is in a location where it's exposed to further contamination, you could cover the whole connection with heat shrink tubing.

Is the connection exposed to constant weather, or battery fumes, etc. Try
to position it so that those effects are minimized, if that is the case. If
not, then I don't have much to add to the good advice others here have
already given you.

liberal application of silicone grease will help a lot. Get it on the plumbing aisle of the home center. DO NOT use regular shrink tube as it is porous and will trap the gas/water vapor making things much worse!

For many years I have seen good results with MG Chemicals "Super Contact Cleaner". Spray it in and then connect/disconnect the connector a couple of times to try to wipe the contact clean.
If you are SERIOUS about removing the intermittent, use a product called "Stabilant". It is a contact enhancer and will make all your troubles go away. It actually promotes a molecular bond between the contacts. They are really proud of this stuff though!
Before using either of these products, try to increase the connector tension as Emery mentioned. The dielectric grease should be applied to the outside of the connector after it's plugged in, to prevent water intrusion.

Rich, I've never heard of heat shrink tubing being porous like that. I just did a Google search and couldn't find anything on heat shrink tubing porosity or permeability, other than the occasional reference to "low permeability". I'm not sure if warning people off of the standard polyolefin heat shrink tubing makes sense in our pedestrian...errr...wheeled applications.
The question of best practices when using dielectric grease (or whether to use it at all) comes up fairly regularly. I find Nye's myth-busting chart to be a good reference.

My advice would be to used the heat shrink tubes that have a meltable sealant in them to keep water out of joints that are exposed to weather/water. Some of these are also resistant to UV degradation. Indoor joints need only the regular heat shrink tubing to provide insulation from short circuits.
