RTV Caulking

[Roger]

The caulking on my 1999 24RB is almost black in some places. Apparently, this is caused by mildew inside the caulking. My research indicates that there is no solution to this other than digging out the old caulk and replacing it. Has anyone else tackled this problem? Results?

Thanks, Roger

Have you tried regular paint thinner and an old toothbrush or household
cleaning solution? Usually it gets only dicolored on the surface.

Camping World has a product called Black Streak Remover. I sometimes see it in the RV section at Wal-mart also. Just spray it on the chalked joints from the spray bottle and wipe off after a minute with a dry towel and the black is gone - works quite well.

The direct clickable Camping World website link for this product is as follows: http://www.campingworld.com/category/black-streak/112

FYI

I tried a bleach solution (1/3 bleach - 2/3 water) in a spray bottle. Sprayed it on and worked it in (gently) with a scrub brush, let it sit for a couple of minutes, washed, then throughly rinsed off. Not perfect, but a BIG improvement.

Years ago, the techs at the Born Free factory told us that they used the pre-moistened "orange" cleaner wipes on discolored caulk seams. Worked very well for us, too. Sometimes takes a little elbow grease. Rinse with plain water immediately, to remove the "orange" cleaning solution.
