Heavy-Duty Pet Urine Odor & Stain Removal Kit

The user is facing severe, years-old pet urine stains and ammonia smell soaked into carpet, padding, and subfloor, and cannot afford professional cleaning or carpet replacement. This is a critical need for an extremely potent, multi-step DIY solution. A comprehensive kit including a concentrated enzyme cleaner, a subfloor sealant/odor blocker, and application tools, specifically designed for extreme, long-term pet contamination, would fill a significant market gap for budget-conscious homeowners.
