I have a customer who I did a house wash, vinyl, 1%, for October 7th who messaged a month later and said the grass looks burnt. The day I washed it had rained that morning/overnight and it was like a swamp in their backyard.
We’ve been trying to trouble shoot it and it turns out they use hummerts dynagreen which we think may have had a reaction with the SH.
Any clues? Any other experience? My mind is boggled on this since I’ve used 3% on dryvit homes and no issues. This is only the 2nd time I would’ve burned anything and the first was bushes with 3%.
Kinda stumped on this.
