Is it okay to leave the GLASSGUARD® Miracle Mould Removal Gel on for longer than the recommended time?Updated 2 months ago
We don't recommend leaving the GLASSGUARD® Miracle Mould Removal Gel on for longer than 5 hours. It is always best to adhere to the processing time on the instructions.
If the mould issue is stubborn and not fully resolved with the 3-5 hour application time, then 100% we would recommend a secondary application.
