Remove mounting foam from stone tiles
I have on my balcony stone tiles and have spilled there mounting foam. It was 95% dried but still stuck horribly.
You will need: detergent, oven cleaner (foam) and carpet knife.
I got everything completely clean (also the joints), proceed as follows: first apply detergent generously PUR and rub in well with the rough side of the sponge. Allow to dry, then apply the oven cleaner and rub in as well.
Then wipe with DRY chick roll. Now you can scrape off the first remains with the carpet knife.
I repeated this three times. Only then did I repeat this repeatedly on the joints.
Finally, everything was again chic as before.
