How do You "Prepare" Sandpaper for Wet Sanding??

Looking for advice on how to "prepare" wet/dry sandpaper for wet sanding.

Used the SEARCH function to no avail!

Should I soak it in plain water or add a drop or two of "Dawn" or alcohol?

How long should it soak? Minutes? Hours? (Mininimum/Maximum)

Is soak time "Grit dependent"?

ANY and all advice greatly appreciated!!

THANX in advance.

A bit of dish liquid and a couple minutes is all I've ever done- but know now that I AM NOT qualified to advise anyone on body work procedures. Actually, I always preferred to use running water whenever I was able.

Hopefully this response will help get you some real advice.

Good luck.

On a new sheet of paper I rub it across another sheet of new paper of the same grit. This kind of knocks off the sharp edges off a new sheet. I then have a squirt bottle of water with a few drops of Dawn dish soap added that I keep the area I'm sanding wet with.

I try and always soak my paper for 10-15 minutes before using it. I like to use a few drops of Dawn in my sanding water mister bottle.

My uncle was a b/f man and told me to never cut my paper with a sharp blade, that I should fold it, then tear it on the crease. His theory was the sharp cut edge could cause scratching and the torn edge did not have a defined edge and as such wouldnt be as subject to causing scratches. I always have done this but to this day wonder if I should do the same to the factory cut edges

Probably doesnt make a bit of difference, but after 40 years I still do it.

I let my sand paper soak in warm water until it becomes soft in most cases 15 minutes or so

I wet-sand with the help of a 5 gal bucket and a sponge.
The bucket's filled about half way with water and given a
squirt of dishwashing detergent. Then I take a clean sponge
and use it to keep the panel wet, while spongeing the sanded
area clean and squeezing the sponge out often.

With new paper, I just wipe it a couple times with the wet
sponge and start sanding. Never thought about soaking the
paper, but I guess it couldn't hurt.....?
