Will strong peroxide from hydro store work best for wpm? There are other products there, should i look at them? And if im wrong and its pollen will anything for wpm wipe out pollen also? Please help quick they close soon and i want to fix this.

You can do a 50/50 mix with the 3% hydrogen peroxide and water. Some even use the 3% straight.
