I have used espec's limonene in house washing, but the problem I have is the instructions only pertain to how to mix it up to make 55 gallons. Thats it. There are no instructions on ratios to use or what it is designed specifically to work on. Plus, no msds. All that fancy lingo in the ad and blamo disappointo.
If you are looking for Limonene to work on mildew or algae, it doesnt. If you are looking for it to clean something, there is nothing stating what it is supposed to clean. Its advertised for house washing, but when I wash a house, it is to remove mildew/algae or oxidation. There are 2 different methods involved in the removal of each. Alone, limonene has not been effective on either. As we all know, dirt falls off the siding just from hot water alone. Mildew/algae need a strong oxidizer to kill it in order to remove it easily, otherwise, you have to beat it off with high pressure (2500psi+) Oxidation is removed well under a 2 step acid/alkaline process and rinsed with hot water under moderate pressure (600-900 psi)
After trying Limonene at a number of concentrations, it now sits on a shelf waiting for a qualified use as a degreaser.
