How pollution cleanup works in Lightyear Frontier
In Lightyear Frontier, pollution mostly means two hazards: Noxious Slime (gooey patches on the ground) and Noxious Weeds (spiky toxic plants). Clearing both is a key part of restoring each region. Your cleanup loop is simple: refill your mech's water tank at water sources (in current builds, standing in water refills it), spray slime with the Irrigation Hose, and remove weeds with the Vacuum Harvester (now labeled Resource Vacuum in recent updates).
If this feels overwhelming at first, you are definitely not alone. Start with one small patch near home and finish it completely. Gather nearby materials, then convert that exact area into active farmland so your effort pays off right away. If resources feel tight, keep your first cleanup paths close to water and your most-used gathering routes to cut down on backtracking.
How to keep restored land healthy
Tip: if you feel stuck, do not try to purify the whole map in one push. Reclaim enough clean space for your next couple of harvest cycles, then stabilize. That gives you steadier supplies for upgrades, which makes the next cleanup wave much easier.
A simple daily rhythm works well: quick cleanup pass around active fields, harvest, replant, then explore. As your mech improves, revisit older zones and link clean travel lanes between your base, fields, and resource spots. In Lightyear Frontier, restoration works best as steady maintenance, not one giant perfect purge.
