Boston ivy has many varieties, and all of them are vigorous, invasive growers. This vine's sucker roots will seek out and adhere to any surface. And if they discover even a small crack in vinyl siding, they will insert themselves and expand, causing considerable damage. When cleaning Boston ivy from vinyl siding, keep in mind that this plant's roots are stronger than they look. Simply yanking the plant down could seriously damage your vinyl siding.
Remove the Boston ivy from your vinyl siding using pruning shears (or scissors) to carefully cut the vine away from its roots. Leave the roots attached to the vinyl siding for a few days--until they turn brown, shrivel and die.
Pull the dead roots off of the vinyl siding with your hand.
Clean the vinyl siding by dipping a soft scrub brush in a bucket of warm, soapy water and scrubbing off any clinging dirt or root tips.
Wipe the cleaned area with a soft cloth.
Uproot the Boston ivy to ensure that the plant does not return.
