I had 20 year old latex caulk on a fiberglass tub/shower unit which remained after removing the shower doors; it was like concrete! This stuff worked lik a charm, but I had to leave it on for at least 24-36 hours (covered with plastic wrap) before I could scrape it off with a plastic scraper. And there was no damage to the fiberglass. I highly recommend it.

This product works! The plastic bottle said to apply a 1/8" coat and leave on for at least two hours, but that some types of caulk may require seven hours to soften. I applied the caulk remover and let it soak in overnight. When I tried to remove the 14-year-old bathtub caulk it came right off with very little effort. It made the job a breeze!

I was surprised when I found that this product also softened the RTV silicone and it crumbled off, but not nearly as easily as the caulk.

I bought this product after my husband couldn't scrape hard, 17-year old caulk off our tub surround without leaving marks on the fiberglass. You apply this stuff over the hard caulk and in a couple hours, you can easily scrape it off with a putty knife or something similar. You may have to reapply to thicker areas if it can't penetrate in one application, but that's not a big deal. I would definitely recommend this to anyone trying to remove rockhard caulk from a surface.

Thank goodness I found this product. We had an addition built on our house with a new bathroom. Well, I'm not sure what the contractor was thinking but the gap between the tub surround and the tub was extremely large and he attempted to shove a boatload of silicone caulk to cover it up. That quickly became a disaster as it really was not water-tight and we were left with a black moldy mess!

It's been so disgusting, we were able to peel a good amount of it off but there was still parts stuck on and this has been magic. I've been able to little by little apply this cream, wait and scape most of it off. I still have a bit to go but it looks tremendously better.

Now, if anyone has any advice what to do with these 1/4 to 1/2 gaps between the tub surround and the tub, I'm all ears! They will continue to have water sit in them until I figure something out.

This product works exactly as described. If I need to remove caulk in the future, I'm buying this product. It was easy to apply and the caulk came off with ease. It says to leave on for up to 7 hours for stubborn caulk, but I didn't have to wait that long. Great product!

I was trying to remove the old caulking on my 18 year bath tub, and boy what a pain! The caulks have became so hard like concrete. I had to remove little piece by piece so I don't damage the bath tub, I spend a couple house per day and 1 week later there are still a lot of caulk left!

Just when I was about to give up, I came to Amazon and search for caulk removing tools, and came to this item. After reading the reviews I decide to give it a try. When I use it for the first time, I was so amazed! This item somehow "melt" the caulks and soften them. The caulks became so easy to remove! If you are having trouble removing old caulks like I do, buy this product, it helps!

My shower needed to be re-caulked and I had already tried another product for a portion of the job. The other product worked but also required a lot of manual scraping to remove the silicone caulk. For the second part of the job I purchased the 3M caulk remover. The difference was significant between the two products. The first product required that the caulk be removed first then it would help remove what was left (sort of). The 3M product didn't require any pre-work just cover the caulk then wait at least 2 hours. I put the caulk remover on the silicone and left it overnight. In the morning I used my scraper and was surprised at how easily the majority of the silicone came right off. There was still a little residue left but nothing significant that wouldn't come off with a little scrapping. I wish I had started the project with the 3M remover! Note: my shower enclosure is ~3 years old so the silicone is not old.

I ordered both the 3M and the Mckanica silicone caulk remover to remove silicon caulk a prior owner of my RV slathered all over the seams. It was impossible to get the caulk off using mechanical methods, boy did I try. The area of the RV I was testing on was a seam between a painted metal flashing and the fiberglass side wall. I applied the 3m first letting it set overnight. Some of the silicon was loosened and with some work came off with a scraper but there was still a good deal of silicone left on the surface. It seamed to only act on the very outer layer of silicone. The paint on the metal flashing came off as well, not exactly what I wanted but the instructions warned that this may happen. At this point I decided that the 3M was not going to suffice. I just couldn't take the time to re-paint and do multiple applications. On to applying the Mckanica. The Mckanica is a gel and comes in a caulking tube. After squeezing a little bit out on a plastic tray I applied it to the same area which proved to be too much for the 3M. After a few hours I came back and wow not only did the Mckanica take off what was left after the 3M application but the areas which were untreated by the 3M but treated by Mckanica came completely clean. You could just wipe the silicone away with a cloth. On top of that the Mckanica did not remove the paint off of the metal flashing like the 3M did. I will be ordering more Mckanica for this project and saving the 3M for bathroom duty.

In the instructions it says to remove from painted surfaces and wallpaper promptly. Also says that remover may affect some plastic surfaces. I guess that that's fair warning. I was removing some hard as rock silicone/acrylic caulk from around my bathtub. The 3M stuff softened it up a fair amount but I still had to apply five times, sometimes leaving the stuff on overnight. As I was cleaning up after a couple of days, I found that where caulk remover had dripped and stayed on the fiberglass tub (Jacuzzi Whirlpool), it had etched out chunks of the finish. Looks pretty bad, big scars on the edges of the tub. Might be o.k. if you're careful enough, wasn't worth it to me.

I purchased this product to aid in the removal of a shower door track along my tub. The track had been in place for at least 30 years. I applied the product and decided to wait several hours (around 7). When I returned, the edges of the caulk were loose enough to score through. Also, the end of the track had already been slighty lifted so the product got under there a bit. I was able to shimmy a scraper under the end of the track and wriggled, pushed and pulled back and forth. Some of the caulk did in fact come out/off. However, I realized that the caulk was hard as cement under the track and had been spread under the entire length/width. I reapplied the product and waited 24 hours. I went back and repeated my process with the scraper. This time I was able to remove some more caulk - enough that I was able to pull the track up off the tub a bit to allow me better access with the scraper. I then reapplied the remover again and waited several hours. This time I was able to completely remove the track. It took LOTS of elbow grease and patience, but overall I am pleased with the product. I definietly would not have been able to get the track off with out the remover. I only wish that a small straw/nozzle was included so one could be more precise with getting the remover into tight spaces.
