Something that I have done for a long time that I have never seen on the forum is use pressurized air. Not from a can like to clean a keyboard but from an air compressor. MAKE SURE THE NOZZLE YOU USE HAS VARIABLE AIR PRESSURE. You can very quickly, and easily, completely destroy a print doing this.
But the idea behind it is moving these globs of resin left over out of crevices and spreading the excess material over a larger area, thinning it out. If you know that your part is going to have excess resin in specific areas use the air to push it out of those areas directly out of the printer, before using the form wash. Then put the part into the form wash for ~5 minutes, as soon as it is complete pull it out of the form wash use the air to immediately dry it. You will immediately see areas that still have resin on them because they will look wet like your original photos. Make sure to use the air and spread the material out again and then wash again for ~5 minutes. If after doing this 2-4 times the area is still covered in excess resin then you need to use the alcohol bottle provided with the washing kit and directly spray the area with alcohol to remove it. Then using the air again immediately dry it.
Just as mentioned before with the UV light only being able to penetrate so far the alcohol can only dissolve so far into the excess resin to remove it. By spreading the excess thin over the larger area the washing will be much more effective in short bursts. It is more labor intensive yes, but you do not have to wait nearly as long to cure and the excess alcohol that has to evaporate off of the parts will never damage your surface finish if you dry it immediately with this method.
One final word of warning, make sure that you have something on the other side of where you are blowing the excess resin/alcohol slurry mixture. This can be rather messy, but if done properly can yield better surface finishes and truly clean parts.
