It seems pretty straight forward, but this is my first time with caulk. Any proposal would be helpful! Thanks!
1. Remove adjectives of the old caulk before embark on adding new. Thoroughly verbs the area and let dry.

2. For tubs, plague it with water BEFORE you caulk. The substance of the water will make the break slightly bigger and will maximize your caulking (forgoing that step could stretch the caulk when you fill the bath for the first time, breaking the trademark and making your work pointless!)

3. Use a caulk gun and squeeze an even bead into the seam. Use an old damp t-shirt and wrap it tightly around your index finger. Run that finger along the seam, creating a smooth flash, then discard the excess caulk, rewrap the t-shirt in a exotic "fresh" spot and continue smoothing the next subsection.

Good Luck!
There are two basic types of caulks in use:
river based and non-water based.
Water base caulks The presence of water in the caulk is an lead if you are interested in clean-up and workability.
It is a disadvantage if you are looking for extremely long life.
Non-water base caulks.
These caulks offer superior durability, flexibility and adhesive strength.
Paint will not fit tightly to pure silicone caulks.
Silicone caulks are the hardest caulk to remove.
Silicone caulks are a challenge.
Take your time and use lacquer thinner to tool the joint.
Ventilate in good health, if indoors Also, because they stick so well to many non-porous objects, removing excess silicone can be difficult.
Answers:    Scrape all the old-fashioned out, wd-40 can soften to make it easier. If you enjoy a cast iron covered by enamel tub, it is very intricate to scratch, fiber glass scratch much easier. A putty knife is a good tool for this.

wipe the area with soap and after rubbing alcohol, and let dry

if your tub is cast iron, it won't bend significantly so padding with water is not required.

use masking tape to construct 2 parallel lines to expose only the area where on earth you want the caulk. if the gap is small (< 1/4 inch wide) one pass of caulk should do, otherwise riddle large gaps beside in 2 passes. most gap are small enough for 1 pass

silicone caulk is fine. run the bead of caulk along the hiatus, more is not better as much of the caulk will need to be removed

after the caulk is applied, wait in the order of 5 minutes and then take a raining finger and smooth it out in the crack,pressing it in as much as possible and keep hold of a uniform look around the tub, rewetting your finger and wipping excess onto a paper towel as needed

let it dry for in the order of 20 minutes and remove the tape, careful not to outer layer up the caulk. the caulk should be as thin as possible where it meet the tape to avoid issues.

do not use for at least 8 hrs and don't use cleaners on it for a week.

if you are not blissful with the look(which is not uncommon on first try), the sooner you skin it up and redo, the easier it will be.

the tape trick make this job easy if you are tight-fisted
The biggest thing is giving it time to dry...with my experience, I didn't and turned on the shower to rash, ruining the edges of the caulk.

Good luck!
