You have to figure out why you have nicks and burrs on your blades. It's not a disease, where two nicks spread and cause more - there's something wrong in the way you're caring for or using your skates and you need to resolve it or you'll just end up with more nicks on the newly-sharpened blades.
Holes at the toe or heel of soakers wouldn't be causing nicks on the edges, so buying new ones probably won't solve the problem. Do you wear your guards when walking around? Are you careful to step over the doorway threshold? Stay out of the hockey boxes? Do you protect the blades with soakers when they're in your bag? Do you wear the skates to/from the car, using the guards to walk? (Bad idea, btw) What else is in your bag that could be causing these? How many hours of skating have you done on them since the last sharpening?
If you skate on outdoor ice, that can definitely dull and nick your blades. The wind blows debris onto the ice, which freezes, so you're skating on ice contaminated with microscopic bits of dirt, grit, leaf matter and bird droppings. There's no way around that, so I'd just get used to seeing nicks instead of letting it psych me out.
A few nicks and burrs shouldn't affect your skating, so don't obsess about always having perfectly honed edges. Most skaters won't notice something so small unless they actually look at the blades. Don't let it psych you out if you're doing okay when skating. If you get them sharpened every time you see a nick, your blades will be dead before the boots break down.
If you wipe the burrs with a clean paper towel and it comes off reddish-colored, then it's rust. Get them sharpened and start using a WD-40 stick to coat the blades with a little oil before you put the soakers on for storage. This is a problem with lower-level skate blades - they're not made of high-quality materials, so they rust more easily.
Oh, and clean out the channels of your skate guards. They tend to collect water, dirt and grit, which grinds into your blades when you wear them. Make sure they're always clean - a scrub with a nail brush usually works well.
Unless it's affecting your skating, don't go running to the sharpener for every little nick. It's just a waste of steel. If it's been 20-30 hours since your last sharpening, then by all means, get them done - you're overdue.
