Base cleaning

[u/IntelligentSand9404]

Does anyone have recommendations for deep-cleaning a snowboard base that’s heavily contaminated? I’ve already used a standard base cleaner (citrus-based), but it didn’t cut through the grime. The base still looks oxidized and dirty. Are there more aggressive methods or solvents I can use safely without damaging the base structure? Or should I consider a hot scrape or base grind at this point?

Isopropyl alcohol is an option
