Just checking with folks here if you routinely replace fuses either inside or in the engine block like a preventative maintenance. I owned my 97 LX450 since 2000 and I have never replaced any of them. Never had fuse blown issue. As a backup, I do have new spare OEM Toyota fuses in the vehicle.

Nope, no need
They either work, or they don't.
Unless you have a corrosion issue there's not really anything to maintain

IME, if you have spares, they never fail; if you fail to keep spares, they will.
Agree with what Malleus said. I carry a couple of the common ones and a spare fusible link and call it good.

Thank you guys for all your suggestions. Appreciate it. I'll just keep the spare fuses along with fusible link.
I live in Hawaii very high humidity and every thing corrodes even. If inside. I use contact grease on connections and have used contact cleaner and lube on the fuses. No issues. Every time I remove a bolt nut or connection I use grease and dielectric grease on electrical. Has made my life a whole lot easier
I've had old rigs that were getting buggy enough to do this, and this is the same technique I generally use. I'm also a big fan of Deoxit as a contact cleaner, though it's too expensive to use like a can of brake clean like I've seen some do with contact cleaner. It really does quite a job on old crusty connections.
Yes anything to keep corrosion at bay. Forgot to mention salt in the air and sometimes wave wash up on the road here. Need to drive through salt water. My newest car is 23 years old and corrosion can get hard to deal with if not dealt with early
I feel you pain living right on the coast, I’m sure the islands are worse.
I live within ~200' of the Ocean with frequent fog and dew forming on anything outside, so IME any unprotected bare metal corrodes quicker than some other environments.
Photo shows a couple of original fuses. The Red 50 amp AM1 fuse in the photo below did not pop due to oxidation however it looked identical (green oxidation) as seen on the Yellow 60 Amp fuse; this type of oxidation apparently can cause increased resistance/heating in the fuse.
Replaced both of these (original) fuses after first spraying/cleaning the fuse box (which did not have green oxidation) with DeOxit while all the fuses were removed and battery disconnected.
FWIW:
New 50 and 60 Amp fuses installed:

Yes it is not fun. I am on north shore Oahu and when we get big surf, some coming in tomorrow, when I drive to and from home it is like a fog in the road. Only this fog is sea mist from the huge waves breaking. Between my son and I we have some classic cars. 90 Toyota pick up 4x4 90 Nissan 240sx. 90 318i 90 fj80. They are not mint, but all in original condition and excellent mechanically. Sad to see them corrode when just sitting in carport, but not much you can do. I have had to replace belt pulleys due to pitting corrosion where the belt rides. Tell my son just enjoy driving them. Nothing last forever
this has to be bait
What is bait. If you like I can send pics. Son washing his 90 now. Don’t consider rr clasic
Exactly
I wouldn’t worry about it/him
