出租房拆掉原地毯后发现很多痕迹，味道似猫尿狗屎极难闻。如果换掉这层板，工程太大，还有别的办法？

I would try Pet Odor Eliminator or similar product first

https://www.amazon.com/Odor-Eliminator-Pet-Carpet-Deodorizer/dp/B07N316V8C/ref=sr_1_14?dib=eyJ2IjoiMSJ9.9HPHHs8-Ea3n8hlSFS5HPjbqx-3BPQDYO6L7iOuo__yjASway4diwqTVZfMvRuPjoz8kc0Ct7ZNMMfM-Nydm075hnPjuSQ-tPlA5eeJYLDD7bgJWk1NlDL002PCBTmf3msjoatOQo0YZNhB05mgCgDl5bxmqZ26lCq5Oyu0xWuQR_mik4wXFwfJS1nRDJVAAeMQeAXHVwC0bw-nLMNYxLTJQSbSM_4oVDxvGobOQXlNNVideCTReHBDg34hW2aTrnAteUGJ52xXsNfU7AhekGDFum5_LZWb5O_j_tKPMc4Q.txBp3x7ISBuasByuy9GfxwLO03uxZjSP6wcLvI7xKMM&dib_tag=se&keywords=urine+neutralizing&qid=1710015392&sr=8-14-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9tdGY&psc=1

If this treatment is not enough, I would try ozone treatment for each area or room using a good powerful ozone generator, something like this: https://www.amazon.com/Enerzen-Commercial-Industrial-Deodorizer-Sterilizer/dp/B00JAP7388/ref=sr_1_1?crid=16UI9CMYB21XR&dib=eyJ2IjoiMSJ9.bqZi06gpP4Wc6uNM3sTt9Z4S54vabfbOvmEc50NbeME_XZxqV6OX2npl4LBbAbV9bo68T7vTDjux6oNHYICl4cuI3HYCpw1IwYoMeEyMluLb-icoSbAkbXdLl9-pR3sxU51TttPsPpJfnSZrv3HalxQwisEotIjGQT6u87L1u4ZcWTcOTeAIwtTe0vh5Hj6lKF15RbSIc8ZIbh3R14_PAPsYo4wxDYTKXU8Cu9wE0W8.lYBlzUqsBSlSLqyPFEJl84JMsndXLV0w1KKDc4HmztA&dib_tag=se&keywords=ozone+generator&qid=1710015634&sprefix=ozone%2Caps%2C138&sr=8-1

谢谢回复。 第二个产品在亚马逊的评价提到的都是烟味，不知道对动物残留的臭味有效吗？

宠物的尿可能多年渗透了角落的subfloor导致有点变形, 70年底房，原计划清洁subfloor， 装LVP

Ozone treatment was helpful

to reduce urine and pet odors in my past experience.  I used the most powerful ozone generator I could afford at the time (many years ago).

I would clean and then treat the affected areas.

Try Hydrogen peroxide and baking soda mixture.

用SCOE可以把这个味道清除掉，有点贵但是很有效。
