MedClean Technologies, Inc. Extends Private Offer to Exchange Warrants

BETHEL, Conn., June 16 /PRNewswire-FirstCall/ -- MedClean Technologies, Inc.
(OTC Bulletin Board: MCLN) announced today that it has extended its previously
announced private offer to exchange all of the Company's existing Common Stock
Purchase Warrants with Initial Exercise Dates between July 11, 2008 and August
29, 2008 ("Existing Warrants") for newly issued Common Stock Purchase
Warrants, with a new lower exercise price, exercisable for a lesser number
shares of our common stock, par value $0.0001 per share ("Common Stock"), and
without a "cashless exercise" right (the "New Warrants").

The offer to exchange previously scheduled to expire at 5:00 p.m., Eastern
Standard Time, on June 16, 2009 (the "Initial Expiration Date"), will now
expire at 5:00 p.m., Eastern Standard Time, on June 30, 2009 (the "Extended
Expiration Date"), unless extended by the Company.

The exercise price of the New Warrants will be determined as of the Extended
Expiration Date and will equal the greater of (1) the volume weighted average
price (VWAP) of the Common Stock for the five consecutive trading days prior
to and including the Extended Expiration Date as reported on the over the
counter bulletin board, multiplied by 2, and (2) $0.0075. For example, if the
five day VWAP on the Extended Expiration Date was $0.002, then the exercise
price of the New Warrants would be $0.0075 per share.

Other than the Extended Expiration Date and a new exercise price determined as
of the Extended Expiration Date as described above, the terms of the Offer to
Exchange have not changed and are as set forth in the previously distributed
Confidential Offering Memorandum, dated May 19, 2009, and the related Letter
of Transmittal.

Holders of Existing Warrants are asked to use the previously distributed
Letter of Transmittal to tender their Existing Warrants to the Company if they
decide to participate in the Offer to Exchange. However, holders are asked to
take note that the correct address of the Company is as follows:

MEDCLEAN TECHNOLOGIES, INC.

BETHEL, CT 06801

Holders who validly tender their Existing Warrants to the Company by the
Initial Expiration Date pursuant to the Offer to Exchange will be able to lock
in a new exercise price of $0.0075 per share, even if the new exercise price
determined as of the Extended Expiration Date is higher than $0.0075 per
share.

Tenders may be withdrawn prior to 5:00 p.m., Eastern Standard Time, on the
Extended Expiration Date unless extended by the Company.
